TATTU Battery-The Magic Weapon of Drone Racing China

In the end of the SHENZHEN international drone exhibition. The Drone Racing China attract attention of many visitors, they are make up of the teams from China, the Netherlands, the United States and so on, they staged a international Drone racing in SHENZHEN, CHINA.

Although the drone racing is still in the primary stage, and a few of rules and technology needs to improve, but it has attracted many UAV hobbyists. Drone racing can fly in the outdoor or indoor, and also put up the glasses, through video transmission system to experience FPV(First Person View) drone racing.
 
Quadcopter in the competition, the fastest speed can reach more than 200 kilometer per hour, combined with various obstacles,lighting effects,etc.,feel so shocked. One of most famous drone racing is Dubai held in 2016, in the event, they prepared as much as $1 million bonuses, and finally the age of 15 British boy won the championship. In March 2016, organized by SHENZHEN association of UAV, joint enterprise, nearly 20 domestic industries established China's first UAV racing league, then began to invite professional referees and drone race team, prepare the UAV racing series.

The drone racing divided into 3 level of knockout,promotion race and finals. There are total of 50 contestants, and about 5000 audiences watched the competition at contest site. Through the fierce competition, in finally, Kunhuang Li and Tao Wang who come from China win the championship and the Second. This drone racing is hold in indoor,and has the complex electromagnetic environment, it's more difficult than outdoor,so crashing can't be avoided. But champion of Kunhuang Li with his superior flying skills, crowned.
In this drone racing China, the champion of Kunhunag Li and the other pilots choose the Tattu FPV battery,it not only the Tattu battery has high profile and favorable comment of rate in the UAV field, but also they test the Tattu lipo battery after the use of trust, so they chose Tattu batteries for this competition.
 
Tattu FPV battery is according to the FPV, they has moderate volume,light weight and high discharge rate. At present,through on average 4 series of lithium battery pack, nominal voltage of 14.8v, the UAV battery capacity most of the 1300mah battery, and lipo battey discharge rate around 75c, using professional 5A battery charger for about 20 minutes. Of course,there are some pilots commonly use the capacity of battery,such as1800mah,1550mah and 1050mah battery.

In the competition, the pilots of the psychological and flight skills is important, but also the performance of battery is good or bad is also very important.

Why Such a Short Time of RC Lipo Battery

The RC lipo battery has a limited life, like as human, cars. Under normal circumstances, RC lipo battery after about 200 times the charge and discharge of storage capacity to the discharge will be significantly decreased, use time is also lower. How to use the 200 times charge-discharge? Or how to extend the battery lifespan? Let's to listen the battery expert's recommend.

At first, charge the highest voltage of 4.20v

It's known to all, 4.20v is always the highest voltage of lipo battery, but with the development of technology and improvement. At present, most of manufacturers of lipo battery can be safe to reach 4.25v, even more of the top technology manufacturers can achieve 4.30v, so 4.30v is the highest voltage at current technology.

Model airplane with lipo battery charger are basic set voltage 4.20v, so use charger of voltage 4.20v to charge the lipo battery is OK, but if you raise the highest voltage to charge (such as 4.35v), they will irreversible damage the lipo battery.

At second, discharge the lowest voltage of 2.75v

Maybe many hobbyists have some questions, why? After research, every RC lipo battery has stage of voltage test from 4.20v to 2.75v. No matter from the battery internal structure theory of data, or from the battery discharge measurement, the lowest voltage is 2.75v.
Remind the important thing to hobbyists,at first tell you the roughly of the battery voltage contrast parameters:

2.75V approximately equal to 0%; 3.56V approximately equal to 5%; 3.70V approximately equal to 10%; 3.75V approximately equal to 20%; 3.85V approximately equal to 50%.
If not do scientific research and the battery with high resolution, the above data can be treated as a standard data. If there couldn't find the same leaves in the world, and also couldn't find two pieces of the same parameters of batteries, only the parameters of similar. So more than the contrast of voltage and power relations we only use symbols to represent "approximately equal to".

From the above battery voltage compare relations you can know, when the battery voltage to 3.56v is only 5% of the electricity, the 5% of the electricity control isn't good, it's easy to reach 0% of the limit value, more than the limit, the battery bilge gas immediately.

At third, within 1c charge current to the RC Lipo battery without injure. 5c charging isn't recommend

Battery charging is a process of converts electrical energy into chemical energy, is a chemical reaction. The chemical reaction has considerable relationship with temperature and pressure. The earliest lithium battery only lithium and manganese substances, the reaction procedure for Li+MnO2=LiMnO2 is REDOX reaction.

Why the cheap RC battery pack has the using lifespan?

According to the experimental data and theoretical prove, within 1c charge current to the battery without injure. More than 2c current will cause the capacity declined slight, and then up to the 5c current, the capacity obvious reduction.
The mainly reason of capacity reduction is the battery internal material generated crystal lead to chemicals. So we use the 1c current to charge is benefits the RC lipo battery.

the main difference between lipo and NIMH battery

Ni-mh batteries A nickel Cmetal hydride battery, abbreviated NiMH or Ni CMH, is usually a variety of rechargeable battery. The chemical reaction on the constructive electrode is similar to that from the nickel Ccadmium cell (NiCd), with each using nickel oxyhydroxide (NiOOH). Even so, the damaging electrodes use a hydrogen-absorbing alloy as a substitute of cadmium. A NiMH battery can have 2 to 3 times the capacity of an equivalent size NiCd, and its energy density can approach that of a lithium-ion battery. Lipo batteries A lithium polymer battery, or far more properly lithium-ion polymer battery (abbreviated variously as LiPo, LIP, Li-poly and others), is usually a rechargeable battery of lithium-ion technologies inside a pouch format. As opposed to cylindrical and prismatic cells, LiPos are available in a soft bundle or pouch, which tends to make them lighter but additionally less rigid.
The designation "lithium polymer" has brought about confusion amongst battery customers because it may be interpreted in two ways. Originally, "lithium polymer" represented a producing technological innovation making use of a polymer electrolyte instead of the more frequent liquid electrolyte. The result is actually a "plastic" cell, which theoretically could be thin, versatile, and produced in different shapes, devoid of danger of electrolyte leakage. The technological innovation hasn't been fully created and commercialized and research is ongoing.
The second which means appeared soon after some companies applied the "polymer" designation to lithium-ion cells contained inside a non-rigid pouch format. That is now one of the most common use, through which "polymer" refers extra to a "polymer casing" (that is certainly, the soft, external container) rather then a "polymer electrolyte". When the design and style is often flat, and light-weight, it is not genuinely a polymer cell, due to the fact the electrolyte continues to be in liquid form, despite the fact that it might be "plasticized" or "gelled" by means of a polymer additive.These cells are often designated as "Lipo 7.4v 5000mah"; nonetheless, from a technological viewpoint, they are really exactly the same since the ones marketed just as "Li-ion", since the underlying electrochemistry may be the exact same.

1. Bodyweight

In each cell from the battery voltage , the NiMH is 1.2V, whilst the lithium battery 3.6V, lithium battery voltage is its three fold. The same style of lithium battery weighs lighter compared to the nickel-metal hydride batteries . We are able to see that every distinct weight battery itself , but because of 3.6V lithium battery substantial voltage, once the output voltage of the same to ensure that just one battery pack can lower the number of third leaving right after forming the battery weight and volume reduction .

2. Memory effect

NiMH batteries have memory result . Therefore, common discharge management can also be needed. This periodic discharge management belongs towards the fuzzy state to become taken care of , even some with no the best information discharge ( or perhaps a number of instances each and every discharge right after discharge are due to distinctive providers differ ) this cumbersome discharge management when applying NiMH batteries can't be avoided . Relative lithium batteries mainly because no memory result, inside a pretty effortless and basic to make use of . It is actually fully with out regard to simply how much residual voltage , direct is often charged , the charging time can be reduced naturally .

3. Self-discharge charge

NiMH batteries from 25 to 35% ( January ) , lithium batteries from 2 to 5% ( May possibly ) . Thereby obtained , the price of self-discharge NiMH batteries a lot increased than lithium .

4.Charging

Nickel-metal hydride batteries and lithium batteries can't overcharge resistance . As a result, the nickel-metal hydride battery frequent current charging PICKCUT control mode on the highest charging voltage , charging stops carry on because the greatest way of charging . The 7.4v lipo battery utilizing continual existing, continuous voltage charging mode is most effective.

5. Application

NiMH batteries: buyer electronic merchandise, remote management toys , hybrid vehicles , renewable energy programs; Lithium Battery: cell phones, laptops, energy tools, electric autos, backup electrical power lights , small home appliances.

what is a quadcopter and to understand the other aircrafts

what is a quadcopter?

Quadcopters are also called multirotors, due to them having 4 or more small rotors instead of one like the traditional helicopter. Some models have more than 4 rotors and are called multirotors. As a general rule, the more rotors a drone has, the stronger and more stable it becomes. This why the more high end professional photography drones have 6 to 8 rotors, but these units are currently thousands of dollars.

How to define aircrafts?

You can find two mostly facets, the definition from the element is the number of the motor, it defines the number of rotor how much N; 2 it truly is rack wing (axis) M, the quantity of that defines the aircraft is M shaft aircraft. We normally of a spacecraft termed M axis N propeller aircraft.

About Tricopter(3-motor)

Tricopter normally has two axis during the plane forward, a shaft within the negative. So your body must seems like T or Y sort. Unfavorable motor modify plane by the rotation in the fixed on the course , tricopter is superior manage, ordinarily also rise quicker, but not drastically. Obviously, when the motor stops operation, so the plane will crash, but this type of model is relatively agile.

About Quadcopter(4-motor)

Quadcopter weight in excess of a tricopter, have been also additional possible to kind, as the quadcopter will not ought to separate to manage the parameters of single motor. They are more secure, along with the flying time is longer,you can carry a high capacity and longer battery,such as Gens ace&Tattu 10000mah battery , quadcopter by reducing the velocity of your two motor to implement the roll, as well as the other two motor can handle the entire from the aircraft.
QuadcopterX(QuadX) or quadcopter (Quad ) has distinctive wingspan, helps make the plane seems to be like an X or maybe.

About Hexcopter and Octocopter(6-moter and 8-moter)

The fundamental design of hexcopter and octocopter are very same. Rotor organized around a central point right into a round shape. There are some model install the rotor in the top rated. Y variety hexcopter looks like a tricopter, but no one in which the parameters with the rotor independent handle. To the contrary, yaw is similar for the four rotor aircraft, by altering the velocity of the motor. Compared with all the independent style and design yaw rotor, such design and style feeling not sensitive in contrast with independent yaw.
Much more rotor enables the vehicle to load better and more secure. Underneath the control on the rotor a lot more aircraft in flight controllers, when one particular or extra on the motor power, still can continue to keep the capability to fly without having crashing. But not surprisingly the total weight of aircraft and its complexity of building and is proportional to your price, along with the number of rotor also need many power supply,also will need more 2s 7.4v Lipo battery to carry.
As a beginner, quadcopter seems to be one of the best introduction to the model. They are easy to set up, and the flight is very stable. But when you start, it is better to ensure that the following two points: as simple as possible, the lighter weight, the better.

Drone Competition is Growing as a High Energy Sport

It was reported by the Wall Street Journal last year that the US billionaire, boss of the team Miami Dolphins , Stephen Ross has invested the Drone Racing League. He invested $1million through his investment company RSE Ventures. The industries of UAV have raised a question when the news came out: Is UAV contest a real sport? Nick Horbacezewski, CEO of the Drone Racing League said: "I think the game has the ability to let people resonate together because it has been not only a traditional racing game but also a game with new technology. Recently it has been reported that the drone competition is expected to become the next emerging sporting events. Unlike most racing sports such as car racing, horse racing or dog sledding there is no driver inside the drone. Drivers need to wear goggles, and they control it according to the video camera embedded in the front of the drone. Such manipulation is known as FPV (first person video). By combining FPV and UAV that participants and spectators could experience the speeds up to 90 miles / hour and give participants an immersive, high-speed flight experience of competition.

In the United States, the two-day U.S. National Drone Racing Championships held in California State Fair in 2005. It attracted 120 participants to participated in and the prize money is reaching a high of $ 25,000. It was reported that the game was expected to attract only 60 spectators, but the videos of UAVs hit on YouTube more than a million. Moreover in France, Australia and the United Kingdom the similar evevnts have been also organized.
In China in November 2015 the International Air Robot Contest (IARC) was held at the Beijing University of Aeronautics and Astronautics, the two play-offs multi-rotor UAV "Shepherd of Action" and "remote through" were added. And the competition rules was setting based on FPV model. Both playoffs game directly push the game to a climax and the applause, screams constantly which made the entire event completely a success.

With the growing popularity of the UAVs and virtual reality goggles equipment, consumer goods of science and technology are increasingly becoming affordable. Related associations, Unions strongly promote and integrate into the modern new technology with God's perspective of the world, the industry of UAV is bond to boil up and FPV drone competition will be growing as a high-energy movement.

Competition of UAVs is on the rise and development. it is a new industry and event planning and preparation will require a lot of time and manpower. The real development of drone competition takes time and it also faces many problems.such as the FPV battery flight time.

Currently, the UAVs on market mainly target lithium polymer battery as the main power. Endurance ability is typically between 20-30 minutes. There are some differences because of different technology but most of their flight time is less than 45 minutes while their charging time is more than one hour. The UAVs can not carry heavy battery with large capacity due to the need to minimize the weight of UAV. Most of the UAV just can maintain ten to twenty minutes in flight then it must be replaced by another battery or plug in the charging cable. So pilots often go out with three to four batteries which is regarded as a primary limits to the development of the UAV industry. To promote the development of the UAV marketing we should putting the problem how to prolong the flying time of UAV into the first place.

In September 2015 Tesla, a leader in the field of electric vehicles, announced a specific application of aerial UAV prototype. Company Tesla showed their scientificalness in rechargeable batteries. It was reported that the UAV was equipped with a 10000mAh battery and a single charge could promise a sustainable flight for 60 minutes and the charging time is only about 20 minutes. Tesla with unique skills has entered the UAV market and it is bound to have a tremendous impact on the domestic UAV battery. Everyone hope to have a kind of battery which charging time is shorter and flying time is longer. But this long-awaited product is still in the phase of conceptual designing.

The research on UAV battery has emerged in endlessly. Currently most of the new products are on the phase of research, and development of the UAVs battery can not be predicted. We hope these UAV battery can live up the expectations.

The application of drone in ecological protection

Due to the unique bird's-eye view, the drone can observe a wider range. The drone can offer you help no matter you are an agency selling real estate or you are a forest patrol.
In fact, drones, a cutting-edge technology, have been applied in ecological preservation areas, which would make the protection works easier. Let us see how it works.

In forest degeneration areas, the traditional plating method needs a large quantity of manual labors, which is time-wasting. In 2015, a new British company designed a drone, which can sow a special seed capsule into the soil. In practice, just like a bullet, the seed capsule would be shot and fixed into the soil. At the same time, the seed will rupture and can be exposed in the sunshine, then it will grow.

That drone can successfully sow ten seeds per minute, and it is estimated that a group of drone can sow 36,000 seeds for maximum every day.

However, the drone can be used before seeding. Scientists can take advantage of drones to make aerial photography towards the forest degeneration areas for the ground mapping. Moreover, the drone is able to supervise the illegal plant-cutting in the forest degeneration areas.

Supervise the habitats

The drones, with light weight and good performance, can shoot the detailed aerial photography, even converted into 3D model. Scientists can quickly identify the change of habitats when they use the drone to shoot systematically such as the periodic shooting for a certain area. The change of habitats can attribute to the the change of density of crown, erosion of river bed, quality and quantity of water, etc.

Drones can make aerial shooting for a large area in very short time. The scientists can analyze the change of the human activity, such as plantation destroy and expansion of the market around the particular habitats through image scaling.

fight against poacher

Drones can use with various tools, and one of them is thermal imaging camera. In some situations, this camera can transfer the video real-time to the researchers. Those two factors make the drones become the effective weapon to attack the poaching. Thermal imaging camera can shoot the human's appearance and shape through the trees and can track the campfire set by the poachers. Tracking poachers by drones is comparatively safe since the poachers often hold the weapons. Knowing the position of poachers contributes to the arrest, and stops the poachers from hiding.

tracking animals

The biologists in ecological preservation areas are using radio to track the displacement distance of animals and their habitat scales and judge whether the animals have entered the prohibited areas (non-preservation areas or human activity areas).

But the radio is regarded as an out-of-date method and time-consuming, because scientists have to go to the regular activity areas of animals in person, track the radio signal on foot and make record. In contrast, the drone can fly following the radio signal and collect the data and image more quickly, so that the scientists can track more animals and acquire more data.

Be against the forest fire

Thermal imaging cameras can also be used in investigating forest fires, avoiding the expansion of fires to cause the serious result. With the help of drones, people can make the quick reaction and control the fire easily.

But the drones can make more contributions to the forest fires. Till now, the firemen have always taken the planes or helicopters to observe the fires. Unfortunately, the firing areas are full of danger, such as the collision of several aircraft in a limited space. The drones can renew the the observation measure and guaranteed the safety of pilots and firemen.

Of course, if the drones are not the only equipment, the drones should cooperate with the aircraft very carefully and precisely.

Drones protect future

Undoubtedly, the drone has changed lots of fields, from estate selling to military activities. Recently, the drone has made contributions to ecological preservation areas and biological field. Now that the ecological protection has not made so much progress, the drone tech would definitely become a popular auxiliary.And also the UAVs flight time is a very popular industry, Gens ace &Tattu lipo battery has a few of reputation in the UAV field, if you interested, you can pay more attention to Gens ace 2s lipo battery and Tattu smart battery.

A breakthrough of the flight time of the industrial level UAVs battery

There's a breakthrough of UAV battery.
In the beginning of this year, the first domestic high mobility X8 multi-rotor drones with 7*24 hours' flight time was release in Chuangzhi Technology Center, Shanghai, China. This drone is called "skyhook" and adopts irregular ground power transmission system to support the continuous flight. It can carry visible light zoom camera, infrared camera, airborne radar and communication antenna to supervise the security, deal with emergency danger and control the traffic. Those are all the impossible missions for the consumer level drones among the market.

the breakthrough of flight time

Previously, the flight time mainly hinders the drone scene application. Skyhook makes the continuous flight come true. Compared with the consumer level drones, Skyhook uses a suit of power supply unit form the ground with the power transmission system, communication signal and a cable made of fiber that can connect with the cars or other fixed device on the ground. All of those ensure that the drone can be mobile can work continuously.

TATTU is remarkable in the field of battery for drones. The ultra-long flight time, smart battery and protection of low voltage are all the strengths. In the storage, compared with the other battery, the Tattu battery can stop discharging once the voltage reaches 3.5V and self-protect(3s 2200mah lipo).

In addition to the flight time, the perception and identification is another main problem for drones.

There are three measures to realize the perception and identification. First, depend on the extra sensor, the radar, because it is hard for drones to fly safely in the shared areas without people's supervision and control. Second, identify the object by the drone's camera, which need strong computation ability. Finally, a traditional computation, which need the drone designed to identify or escape the threat by the precise computation, and comprehend how the object is identified while moving. Skyhook adopts that carrying different devices such as infrared camera and laser radar 3D scanning topography, and analyzes by the returned images.

No matter which measure, the key is to let drones know their surrounding, which is very helpful, even though the application scenarios are very limited. For example, they can identify whether there is hole on the frozen roads, find the fires while patrolling in the forest, and find the footprints of the missing climbers.

The diversity of application scenarios

For next steps, some company will research how to carry different load to accomplish tasks according to the application scenarios. For example, the forestry has comparatively low automation rate, and the drones can fly for patrol 24 hours instead of labor. Another application scenario that can be imagined is that in the disaster of Tianjin explosion, drones can be used to test the temperature, gas composition and microarticle in the air. Also, with the visible light and infrared camera, it can search the signs of life.

In recent years, drones have been firstly applied in the anti-terrorist, drug control, traffic dispersion, fire-fighting and other safety tasks. The quantity of purchase has been increased. In 2014, the public security organization has purchased more than 60 drones, and until the third season, 2015, the public security organization has purchase over 300 drones, which is five times more than 2014.

Drones have developed dramatically from civil use to commercial use.

Drones also applied in agriculture irrigation. The drones can irrigate 40 times faster than manual irrigation. Using the microwave radar, drones can scan the ground in real time, keep a suitable distance and control the volume of liquid. It can fly 8 meters per second, and cover the crops with liquid evenly. It can switch the mode among fully automatic, half-automatic and manual operation, and has the property of dust protection, waterproof, corrosion resistance. Furthermore, it can fold.

Apart from the agriculture, the traditional geography has taken advantage of the professional drones, such as monitoring weathering, observing the change of river and glacier. The archaeologist and historian are using the drones loaded with common digital cameras to 3c modelling and restore the scene of ancient architecture relics.

The wide range of application brings new trouble for drones. The drones have the characteristics of low altitude, low speed, small objective, so they are hard to supervision, detect and dispose, especially the prevention and control. It need further observation and research that how to regulate this safety factors, since illegal photography or delivering drugs is a countless phenomenon.

Do you already know the various between FPV and aerial photography machine?

For many newbie,they can be normally confounding FPV with aerial photography machine.Which will lead them make an blunder after they gonna purchase new drones.It may very well be wasting money.

Thinking about about this kind of standing, i'd prefer to share with folks that what's the various amongst FPV and aerial photography machine.

Firstly,i wanna allow you to understand that the widespread point of FPV and aerial photography machine is they all install a camera on drone.So in this stage,the drone is just not the key part,and just like a carrier for aerial photography or FPV.

The primarily diverse among FPV(3s 1300mah lipo) and aerial photography machine is they are really pursue distinctive objectives,really.

The aerial photography machine is absolutely diverse towards the typical view.It can be extra magnificent and sublime.Angle,picture high quality and photography techniques would be the essential points for aerial photography.Or,you can say,aerial photography is form of artistic creation by utilizing drones.Moreover,aerial photography also can be used in measurement, survey etc.Although,they are not artistic creation,but in addition for receiving video clips and pics.

People would like have the freely fly feeling within the sky by FPV.The so referred to as PFV total identify is 1st Man or woman View,You may drive your drone,crossing in the jungle,gazing down 1 the earth.In this stage,FPV doesn't have that substantial picture good quality around aerial photography.

While you know in my first point,aerial photography requires very good picture high quality,so the machine ought to use good quality photographic camera tools and secure PTZ.It means that the drones have fantastic weight-carrying means,so that the drones could afford all of the weight on it.For FPV,its photographic procedure is a great deal easy and uncomplicated.It only wants one camera.So,the drone of FPV is smaller sized,generally it uses 240-280 wheelbase.

At the current stage,on the earth industry,we nonetheless don't have finished FPV. Frequently, folks have a tendency to self-packing.

As an required accessories for drones,battery is like the blood to drones.The aerial photography machine wants secure image,as FPV needs swiftly explosive electrical power.Right here i'd wish to introduce one particular famous brand in generating batteries----Gensace/Tattu from Grepow.Tattu is largely for FPV battery,Gensace for UAV and RC vehicles.Like a brand manufacturer,Grepow always stick to only produce superior quality for FPV,UAV,RC automobiles.As being a consequence,Gens ace and Tattu take pleasure in good status throughout the entire world.Thus far,Grepow have established two branches in Dusseldorf Germany Europe and L.A American.As a result Costumers could less difficult buy batteries they need.

The difference between Single Rotor drone and Helicopter

When it comes to UAV, the picture of quadcopter strikes everyone, but is that only the quadcopter reliable? Gens ACE- 3s 1300mah lipo, specialized in providing the battery for UAV and RC model and seeing numerous UAVs, will introduce you a new and novel air vehicle! Recently, foreign press reported that American researchers created a UAV with only one rotor. This UAV adopt the asymmetrical design, and more importantly, the only part of it which could move is a single propeller.
This UAV is called single channel rotor aircraft. The whole aircraft is controlled by a simple propeller, with a propeller that can move and without flap, hinge, aileron and even other actuator and controller. Although its mechanically design is simple, the electronic programming is advanced which is precise enough to travel in the air stably.

Do you think there is no difference between it and one-rotor helicopter?

No, they are considerably different.
In the field of UAVs, the most common aircrafts are divided into fixed-wing, helicopter and multi-rotors (the mainstream in the multi-rotors is quadcopter.). This aircraft is transform the multi-rotors into single-rotor, which has huge difference from helicopter.
A few years ago, helicopter and fixed-wing just take the most part of UAVs, almost no multi-rotors. However, the release of DJI Phantom broke this dominance. One of the most important reasons is that Phantom dramatically reduce the difficulty and cost of aerial photo. It is applauded by the market and become the best-seller product so far. In the following two years, the originality and design of multi-rotor aircraft come out endlessly.
Another crucial reason is that the reliability of the machine is considerable, which is also the main difference between multi-rotors and helicopters.
Compared with the multi-rotors UAVs, the helicopter should consist of thousands of movable machinery parts. The abrasion, during the fight, causes the reliability decline. Not to mention the high cost of trouble-shooting of such unstable elements, threatening the people's health is possible. Conversely, there is no movable components on the multi-rotors. Its reliability depends on the reliability of the brushless motor, so the reliability is high. The helicopter has more complex structure and more movable machinery parts.

Besides, helicopters usually need stroke oar and a pair of rotor, towards opposite direction, to keep the balance, and the single-rotor UVAs, however, need only one rotor, which adopt the asymmetrical and unbalanced body design to ensure the flight and the controllability. Actually, tens of years ago, the aircraft operated by skilled pilots included only two movable components-the rotor and rudder. The "single channel rotor aircraft" proved that only one movable part for the remote aircraft is enough. However, compared with the helicopter and quadcopter, the calculation programming of the "single channel rotor aircraft" is much more simple. In other words, to let it launch, we should apply the correct method, and the success rate depends on the manual operation. What is more, its sensitivity of operation is comparatively weak. Because when it launches, it has to rotate continuously to keep balance, it is not competent for aerial photograph and other tasks.
Although there are many sorts of UAVs, the battery is vital. Gens ACE-14.8v lipo battery, specialized in providing the battery for UAV and RC model for many years, is worth being recommended.

Compared the polymer battery with the liquid Lithium-ion battery

Compared with the liquid Lithium-ion battery, Lipo battery adopts the thinner aluminum film and the different production method. The thinner the polymer, the easier the manufacturers produce. The battery whose thickness is less than 0.5mm can be produced in theory. Opposite, the thicker the liquid Lithium battery, the easier the manufacturers produce. It is quite hard to make the battery whose thickness is less than 4mm, which has weakness in the capacity. Therefore, the thinner the batteries, the less cost the polymer production has and the more cost the liquid production has.

For the thick specification, the liquid Lithium battery has complete supply chain and technology, high production efficiency, high rate of finished products and cost advantage of manufacture. From the market, though the battery of 5,6mm in thickness has more capacity than the battery of 3,4mm, the 5,6mm battery has lower price. In theory of polymer, the material cost of 5,6mm battery is similar to that of liquid battery. However, nowadays, the process cost is much more than the liquid one. Therefore, there is some gap to form competition between polymer battery and liquid battery from the specification.
Among the recent polymer Li-ion battery, polymer materials are mainly applied in anode and electrolyte. The anode materials include macromolecule polymer or inorganic compound adopted by normal lithium battery, and the electrolyte can use the solid, colloidal macromolecule electrolyte or the organic electrolyte. The cathode always uses the Lithium metal or Lithium-carbon interlamination compound.
The liquid or colloidal electrolyte puts much weight and cost on the Lipo battery and restricts the flexibility of size. However, there is no extra electrolyte in the Lithium polymer technology, so it is more stable. That is to say., there is unlikely to cause danger if the battery is overcharged, punctured, collided, overused and destroyed in other ways.

The new 5000mah Lipo battery has stronger flexibility to meet the products' demand, since it can become thin in shape (0.8mm for the thinnest one), area normalization and shape normalization. To make battery of any shape and capacity provide the manufacturers with the flexible design and adaptability to optimize the performance. At the same time, the unit energy of lipo battery increases by 50%, and other aspects have improvement like capacity, characteristics of charging and discharging, safety, the range of working temperature, cycle times (more than 500 times) and environmental performance. Gens ace 2s lipo battery has a long lifespan,it is better than others.

Lipo Battery strengths:

1.Ultra-thin
2.Flexible: manufacturers can adjust the volume economically rather than the fixed shape.
3.Light: Polymer electrolyte battery does not use the metal cover as the external package.
4.Safety: the electrolyte is unlikely to leak, so it is more stable.Like as the Tattu lipo battery.

Shortage:

1.Compared with Li-ion battery, the Lipo battery has weakness in energy density and cycle times.
2.High cost

The distinctions between Smart Battery And Ordinary Battery

The DJI new-released M600 brings significant breakthrough to your all UAV Location. Not simply the A3's self-adaptive flight techniques and new RONIN-MX is , but additionally the rather extended flight time supported by six sensible batteries.
It introduces that a custom-made battery management system and energy distribution board lets all 6 batteries for being turned on with a single button press, and keeps the system in flight during the occasion of a failure of the single battery, and allows customers to check out the battery standing in real-time throughout flight.

As many of us know, M100 has adopted intelligent batteries to help the big heavy device for extra expert aerial photography and longer time and distance making use of. Then what are the differences among Intelligent Battery and Ordinary Battery, why they are additional and much more widely made use of from the electronic ndustry?

1. Definition

A clever battery/A good battery system(SBS) is usually a rechargeable battery pack equipped using a built-in battery management process. The clever battery can internally measure voltage and existing, and deduce charge degree and SoH (State of Health) parameters, indicating the state with the cells, calculated and predicted information and facts to its SMBus Host below software package management.
A essential SBS like 3parts:Program Host,Sensible Charger and Intelligent Battery.

1.1 Positive aspects

Ordinary Battery

Ordinary Batteries are illusive and don't exhibit noticeable modifications as part of usage from each the user's along with the equipment's perspective. It appears the same when completely charged or empty, new or outdated and in have to have of replacement. A really massive defect is the fact that they signify an unpredictable supply of power.
Firstly, a consumer has very little know-how that their battery is about to run out or simply how much working time is left.
Secondly, products powered from the battery are not able to ascertain in the event the battery, in its existing state, is capable of supplying ample electrical power for an additional load (such as spinning up a difficult disk) or not.

Smart Battery

The Intelligent Battery presents a perfect resolution for several of the issues linked to batteries used in moveable electronic gear.

The Intelligent Battery provides the consumer with accurate state of charge data together with an precise prediction from the remaining working time.
Additionally, it Provides state-of-charge and full charge capacity; reflects capacity estimations; information battery historical past; together with cycle count, utilization pattern, servicing specifications, max error, and so on; configures charger on the right algorithm; reminds consumer of periodic support; protects battery from unauthorized use; and to reduce accidental method cut-off.

That is why clever battery is much more and even more popular and extensively employed.
A great good battery brand-Tattu plus(Gens ace 2s lipo), also have all these strengths when employing in your drones.

1.2 Charger

Ordinary Batteries chargers: It has to be individually tailored for use which has a particular battery size and chemistry and may perhaps lead to harm if applied on one more battery.
Wise Battery Charger: It periodically communicates that has a Sensible Battery and alters its charging characteristics in response to information presented by the Intelligent Battery.

1.3 Defects

The Clever Battery will include 25% towards the cost when compared to a Ordinary Battery.

It complicates the charger, most chargers for intelligent batteries are hybrid and also service for non-intelligent batteries.Necessitates periodic calibration.

In contrast together with the Wise Battery's down sides, it's much more and useful functions.We believe in the future, people will creat extra progressived technological innovation on Good Battery and conquer the value as well as other issues stage by step.

Battery Life Regarded as a Factor to Influence the Wind Direction of UAV

In recent years, with the rapid development of the UAV industry, A number of well-known enterprises such as Dji and Corbett Aviation emerged on the market and causes continued focus from capital and industry giants. However, the short flight time (general consumer drones only 20 minutes or so) still limit the application and development of the UAV. How to solve the problem of battery with short flight time? What role can IC products play in this area?

Flight time is less than 45 minutes but Charging over 1 hour

With the development of science and technology in recent years the application of UAV has expand from military to civilian areas, and it becomes more and more popular. According to the forecasts from research firm BI Intelligence, the next 10 years UAV will account for the UAV market share of 12%, valued at $ 98 billion. The current market size is 30 billion RMB in the UAV market. with the improvement of our airspace and UAV open regulatory policy, the next 10 years China's civilian UAV growth is expected to exceed 30%.
However, at the same time in the fast start of UAV market , the limited flight time and other constraints have gradually become prominent. Flight time has been a limit in the development of UAV technology. Currently, the UAV battery on market ofthen use lithium battery as the main driving force, and endurance is typically between 20-30 minutes. This is a major short board of the development of UAV, greatly limiting the overall potential of the UAV industry.
According to the reporter's investigation, the UAV on market including Dji and multi-rotor mostly use lithium batteries as an energy source currently. Because lithium batteries with mature technology are easy to purchase. But individual differences, incomplete balanced charge and discharge, and long charging time for high power battery make it more cumbersome to use. The biggest problem is flight time. Lithium battery with the weight of 300 grams theoretically allow UAV with 500 grams weight to flight 17 minutes, even taking into account the technical differences, as well as the body weight and other factors, the flight time of vast majority of UAVs are all within 45 minutes. But the charging time is more than one hour.
Therefore, it is a challenge for all UAV manufacturers must face: how to enhance UAV endurance and allowed them to meet consumer or even industrial market demand.

Power management chip technology plays a important role of UAVs on market

The biggest problem we are facing is the lithium battery of UAVs with short flight time. It is no breakthrough in the material of lithium battery.In that case, there are two ways to solve the problem: some manufacturers began to try new replacement materials for lithium battery ; Adopting technology of power management chip to achieve effective energy management. Prolong flight time of battery to the utmost extent and charge battery fast.

HUS company in Singapore developed the first multiaxial UAV HYCOPTER using hydrogen fuel cell in May 2015. It can fly continuously for four hours with no load, even under full load of 1 kg can still support 150 minutes. Currently, Dji, Corbett aviation and other manufacturers are also making use of hydrogen fuel cells attempt.
However, as the most common materials, lithium battery with solid power, mature technology, and the use of safety are still the most preferred electricity choice for consumer drones. For example, in September 2015, a leader in the field of electric vehicles, Tesla publicly announced a specific application of aerial UAV prototype. With its strength in battery and power management technology, a UAV from Tesla equipped 10000mAh battery. It can fly 60 minutes a single charge, and the charging time is only about 20 minutes.

In this case, the superior power management chip technology has become one of the key factors to affect the success or failure of the UAV market.

The key point is to find a balance charge

So how the current power management chip technology develop in the UAV market? According to reports, battery management chip is a kind of chip to perform condition monitoring, security management and charge management of battery of electronic device. It can control the voltage of charge current , promise the security of battery, and predict accurately on remaining capacity of battery. IC performance of battery management has a great impact on the operation and use of electronic security equipment

Power management chip has very broad applications, and it is widely used in smart phones, laptops, charging treasure, tablet PCs, smart wearable devices and other products. At the same time, as the quantity of electronic products increases using the power management chip to achieve fast charging has been in the leading place on market.

UAV is the most promising market to achieve fast charging. According to reports, from power management chip, there are similar solutions between smart phones and UAVs. However, charging the phone is subjected to the restriction of USB interface and battery. USB interface typically supplies at 5V . Currently, the highest voltage of mobile phone battery is generally 4.2V, and the high voltage of fast charge eventually drop itself to a voltage the phone battery can withstand and then increase the current to achieve fast charge. The Principle of UAV fast charge, although the same with mobile phone, need to increase their voltage or current, but the difference is, the battery may be made up of several lithium cells (such as three cells 3 * 4 = 12V, that is, to charge the battery at 12V). Because the realization of the tandem cell, we need to consider the balance charging problem to prevent the accidents caused by charge imbalance.

As for the future technological development, on one hand, fast charge technology of the mobile phone is trying to find a high voltage (such as 12V) for mobile phone into a high current. On the other, attention need to be paid to the phone adapter and communication protocols to prevent high voltage burning the phone . There are no restrictions in UAVs, and it is the fastest as long as each cell can withstand the maximum voltage and current. Therefore, there is great room for the development of the technology of UAV fast charge in the future.

Why my drone simple to crash?

As the drone more into people's lives, the crashing drone inevitably come to be to a scorching topic, since for being truthful, frying a machine is as well uncomplicated,while the worst knowledge a drone pilot can face is crashing or shedding your drone through flight. Plenty of new classmate don't have very good instruction, or lack of corresponding processing experience, they normally crashed of ignorance, the causes are various.the reason may be divided into two broad categories:

Prior to flight:

No calibration of GPS and also the compass;
No number of stars on GPS, weak star flight;
Didn't tighten the screw. Propeller should verify once again;
Didn't verify the electric amount of 22.2v Lipo battery. Many people will put together numerous batteries, at times,but they did not press the button to view if the energy enough once they very first fly;
Unfamiliar with the remote control , do not even know when they accidentally set to Japan's hand.

Throughout flight:

Bump a tree, developing, hit anything at all;

Lack of control skill bring about the disorder direction right after the drone fly over-the-horizon;

With the interference spot in the course of flight;

Ignored the sudden wind or windy weather;

From brake management bring about drone roll fell.
To assist you avoid this predicament, we're going to explain the biggest dangers to you and everything you can do to prevent them.

Know Your Drone Piloting Abilities

The biggest danger for your drone is oneself, in particular should you're a brand new pilot or doing work with unfamiliar products. The odds are if some thing goes incorrect throughout your flight, you triggered the issue!
Start out out lower and slow. We all know the best joys of flying a drone can come from soaring around higher up inside the sky, maybe even capturing some killer video, but you have to learn while flying 15-30 feet off the ground just before taking it any higher. For the duration of a worst-case scenario (heading to get a tree/building, operating from battery, losing handle, etc.) you have to get your drone back to the ground ASAP.
Treat New Equipment being a New Drone. If you include new equipment to your drone (like attaching a new camera on your Phantom), treat your flight as though it's a totally new drone you might want to master. Matters like dealing with and RC Lipo battery life might be impacted and could bring about some poor outcomes in case you treat it as though absolutely nothing has modified.

Steer clear of Obstacles

This goes along with flying inside of your limits, but one of the most typical causes of crashes are attributable to flying your drone into objects like trees and buildings. It's also one of the simplest methods to drop your drone acquiring it caught with the top of the 60 foot tree, or on leading of a building you don't have entry to (plus the owners may well not be so great).

Start off out by flying in an open field, away from any trees, buildings, bodies of water, or roadways. This is actually the safest method to make certain your drone comes dwelling with you.

Weather Can Kill Your Drone

An additional important threat for your drone is weather itself. Thankfully, it's very easy to prevent in case you just place within a little time researching climate reviews ahead of hand.
Check the climate report prior to you fly If there's a chance of rain, conserve your flying for a different day! Superior to get protected than have your drone come crashing to the earth resulting from technical malfunctions from having moist.
Know the wind gusts. Make sure you check out the current wind ailments on the weather app in advance of take-off. Most novice pilots can manage wind speeds of 5-10 MPH with out a lot problem. In case you see wind speeds at 15 MPH or over, you must reconsider flying near any obstacles or with a lot of altitude. You might uncover your drone caught in the wind gust that didn't exist at reduce altitudes, and it could carry your drone away or capsize it.

the different drone between UAV and RC aircraft or toy airplane

Nowadays no matter UAV , rc aircraft,toy airplane,are all called drone by the public , and this make the lines between them becoming more and more blur...... The UAV was first developed after the World War 1 , but it was generally used in military after the World War 2. Recent years , UAV has showed its possibility for commercial and civil use. While DJI becomes more and more popular in UAV area,

the technology of UAV for civil use turn to be more and more mature and common . UAV , rc aircaft and toy airplane can be found in every shopping center. But nowadays no matter UAV , model airplane or toy airplane are all called UAV by the public , and this make the lines between them becoming more and more blur , as a practitioner or a hobbyist can you come out with the different drone between UAV , RC airplane and toy airplane in accurate?

The differences between UAV and rc aircraft

First , let's talk about the differences between UAV and rc aircraft.
Let's start from definition , flight control system , Auto-Control , constituent , purpose and administration to organize the differences between UAV and model airplane , in order to fundamentally distinguish.

The differences of definition

Currently , the definition of rc aircraft is that the model airplane must be in your horizon. People's horizon should under 500 meters. It means that while people standing here and look at the model , this distance can not exceed 500 meters and the relative height can not exceed 120 meters. It is a kind of unmanned air craft that heavier than air , has limited in size and has or no power plant and should fly in horizon. That is what we call model airplane.

UAV is totally different , it is a kind of unmanned air craft that use radio remote control equipment or its own program to control. It can fly without remote , people can control it through computer , ground station or ground circuit. UAV can fly thousands of kilometers away and now it can stay in air for 48 hours that means 2 days , it can fly so far in that situation. UAV can fly for a long distance , that is also a notable feature of it , which model airplane can not do it.

The differences of flight control system

The only difference is that whether has navigation flight system and whether can autonomous flight. Popular to say , UAV use its complicated central flight control system to connect with ground control parameters , in order to control its stance and maneuvering achieve autonomous flight.

Though model airplane is also unmanned , but it need to fly in manipulator's horizon and let manipulator to control its maneuvering and regulate its stance.
That's means UAV flies with its "brain" , the "brain" maybe limited by A.I. , not as smart as human's brain. But model airplane's "brain" is always on the ground , in manipulator's hands.

The differences of Auto-Control

In Auto-Control , UAV can deal with many various situation intelligent , complete the mission as required , confirm the mission after data fusion with the ground station and take the next step as required. While most model airplane's Auto-Control only can achieve auto return after lose control.

The difference of constituent

UAV is more complicated than model airplane in constituent. Rc aircraft is composed by flying platform , power system and the rocker in horizon. It is mainly for ornamental of the public , pursuit of out looking or elegance of flying , do not need high technology.

UAV's system is composed by flying platform , power system , Flight control navigation system , link system , mission system and ground station. It is mainly for accomplish some special missions , pursued the ability to complete the task and high technology. Some upscale model airplanes and some low end UAVs do not have too many differences in flying platform , power system.

The differences of use

UAV is more used to carry out some missions that out of horizon , nowadays is mainly used in military and special civil , its biggest mission radius is thousands of kilometers. It can control itself through airborne navigation flight control system. Through link system upload control order and download task information.

Model airplane usually flies in horizon , its control radius is less than 800 meters , manipulator should staring at the plane , use the remote to control the model , there has none equipment on the airplane. Lots of UAV system have the same ability as model airplane , manipulator can control UAV in horizon.

The differences of Security Management

In our country , rc aircraft is managed by Air Sports Management Center , which belongs to National Sports Commission. Civil UAVs are managed by Civil Aviation Authority and military UAVs are managed by military.

The differences between rc aircraft and toy airplane

The differences of participatory

The differences between model airplane and toy airplane is that toys are "dead" , but models are "alive". The reason for toys are "dead" is that toys usually only use its original accessories and almost do not have any choices , if it is broken , people can only buy original accessories , it is also difficult to find.
But rc aircraft is totally different , for example if my television is broken , I can buy whatever size of TV as I want , because all of them are in common use , if I think the old one do not have enough power , I can change it into a bigger one in common use. After all , if you buy a toy , it will always look the same. If you buy a model , you can do whatever you want on it.

The differences of internal structure

From the internal structure , toy axis's ESC , receiver and flight control system are all combined together , all use coreless motor and also do not have the problem of radiating. The advantage for this integrated board is cheap and small in size , the disadvantage is that if one place is broken , then it should be changed into a new one. But because of the expensive cost of model airplane and the need of diy and radiating , so there do not have many integrated board model (except some miniature model craft) , are generally independent devices connected to each other , such as 2s 7.4v lipo battery, easy to use,and if don't have electricity,just replace a battery at any time.

The differences of environment

Model usually can fit outdoor fly and it can be controlled in bad weather. But toy can only fly with breeze or without wind such as indoor environment.

The method of extending battery life

UAV (short for Unmanned Aerial Vehicle) , is a kind of unmanned aircraft that use radio remote control equipment and its own control system to control. From a technical point of view it can be classified into unmanned helicopters, unmanned fixed-wing aircraft , unmanned multi-rotor aircraft , unmanned airship , wing unmanned aircraft etc. From application side , it can be classified into military use and civil use. In military terms , UAV can be divided into reconnaissance aircraft and target aircraft. In civil terms , it mainly used in aerial , agriculture plant protection and mapping. UAV + industry application , is the real need in UAV and it will expand its own use.

The UAV power management

Power management means how to distribution the power to different parts effective. Power management is especially important for some mobile devices which rely on battery power. Through Reduce energy consumption when idle assembly , a superior power management system can extend the life of battery two or three times longer. Power management is also called power control.

Nowadays the mainly devices of power management in the market included PMIC and PMU. Power Management Integrated Circuits , is the circuit that take on energy transformation, distribution , testing and other power management functions in electronic equipment systems. It's main duty is to identify the power amplitude of CPU , then produce short wave moment and promote the power output stage circuit. Power Management Integrated Circuits can be in-line package and adhesive surface package. The range of application of Power Management Integrated Circuits is pretty wild , develop Power Management Integrated Circuits has important meaning for increase the performance of UAV , it also directly related to the choices of Power Management Integrated Circuits and the need of system.

The category of power management is pretty wide , it conclude separate power conversion ( mainly DC to DC ) , separate power distribution and testing , it also include the system that combine by power change and power management. Accordingly, the power management circuits classification also includes these aspects , such as Linear power chip , voltage reference chip, the switching power supply chip , LCD driver chips , LED driver chip , a voltage detector chip , 22.2v lipo battery charge management chip , etc.If the design of the circuit requires a high power supply noise and ripple rejection , Requirements occupied PCB area small ( such as mobile phones and other handhold electronic products ) , the power supply circuit does not allow the use of inductors ( such as mobile phones ) , Power is required to have an instantaneous calibration and self-test status output function requires the regulator pressure drop and its low power consumption , low cost and program simple lines , then the linear power supply is the best choice.

This kind of power include following aspects :precision voltage reference , a high-performance , low-noise op amps , low dropout regulator , low quiescent current. Power management Unit , is a kind of highly integrated , portable applications for power management scheme , it means that put the traditional separation of certain types of power management chips and other devices integrated within a single package of , which can achieve higher power conversion efficiency and lower power consumption , and a smaller number of components to accommodate the reduced board space.

PMU role in UAV Power Management

PMU is widely used in UAV products , its main role are the following
1.It provide a stable and reliable power supply to the various components of the UAV.
2.PMU Helps reduce overall system power consumption , and by reducing the power of the component when idle , so that UAVs can have a longer battery life. For example Gens ace 2s lipo battery.
3.PMU has good signal to noise rejection and transient response , better able to prevent the effects of drones by the external environment and fast transient response.
4.PMU integration features can save internal structure of space , contributes to miniaturization and more cost advantages as well as the entire system power supply system of unified and orderly.

PMU UAV ground remote control unit can supply power to the various components , ensure that all components of the normal power supply , and can filter out interference from outside noise to a certain extent, better guarantee the accuracy of the remote control , at the same time , enabling long lifetime of battery. UAV Flight Control master unit PMU power management module assembly unit to include portions of the flight control master , ESC power supply unit , etc. , to ensure the normal and stable fly control unit work.

Frequently mistakes when driving RC cars

1.Reversing of the starter. If you want to start your car, the starter should be moved forward, especially for those have hand system, reversing will broke the rope or unidirectional.

2.The unstable installation of air filters. Thin ropes can be used to fastened at the bottom of air filters before the rope to be deformed .

3.Lack of power. You'd better to charge your RC car batteries lipo the day before you are going to driving your car, and that's include the telecontrol, receiver, plug.

4.Check the oil in air filter. You should check the oil in air filter before you drive to make sure the oil is enough.

5.To stop the engine by air filter. Do not do that in any cases or the air filter will be transformed, easy to have sands and have a big opportunity to let the oil into engine.

6.Tubing. Check if there is any broken hole in the tubing, the hole will cause the unsteady of engine. Pay attention to the smooth of tubing and make sure the interface of cylinder and exhaust pipe should be matched correctly.

7.The space of gear, too tight or too loose are both easy to be damaged because of overheating. One piece of paper for the gap between two gears is enough, and should pay attention to check if it is smooth enough for the big gear to turn around.

8.Glue of screw. All of the screws locked on the metal should be gelatinized, the better way is to gelatinize some on the screws, pinching them by your figure then turn around and just move out the rest of the glue.

9.Demolition of burner. In case of the sands drop in, you should clean up the sands before dismantling. And replace the burner as soon as it has any problems, because when the burner is burning, metal wire are easy to drop inside cylinder and that will damage cylinder.

10.The clutch. Flail block and bearing should be checked regularly, because it's easy to damage the engine for not smooth. And so do the spring of fail block should be checked regularly.

11.After Run Oil. After driving, you need to put 2-3 drop oil for both burner and the mouth of carburettor. Remember to lean it before to separate the burner and air Seperator.
Exhaust pipe. Check the plastic gooseneck (including engine to curve gooseneck, curve gooseneck to exhaust pipe) which is connected with exhaust, if there's loosing or leaking. If there is a screw on the engine, you can gelatinize on it; if there is a spring, then you can add one more safety rope.

How to NiMH battery care and purchase

NiMH battery can be charged 500 to 1000 times in its lifespan according to the official claim but this is actually an ideal value. It is often less than this data. But if the charger is used in a reasonable way and the battery always get proper maintenance we can still get it to reach "longevity".

1.When we get NiMH rechargeable batteries, can we use them immediately ?

Under normal circumstances, the new NIMH rechargeable batteries only contain a small amount of electricity so you have to recharge it before using. However, if the leave time of the battery is short and the power is adequate the suggestion is use it first and then recharge it. It is same as 5000mah lipo battery.

2. Why the actual capacity of the battery is lower than the nominal?

Generally the new NIMH rechargeable battery need to charge and use for 3to 4 times before it plays to the best performance. There are differences between the capacity of the battery and the capacity indicated when first charged because the smart battery charger's judgement to a new battery is not reliable. Sometimes the battery can't be fully charged. The current of fast charge is too high to fully charge and activate the battery. This is why the capacity measured is lower than the actual capacity. So our suggestion is using a slow charger for ten hours first.
And then discharged with a smart charger and after three cycles it can be to the maximum capacity. The dischargeable capacity also need to be measured and these problems have been solved during the process of the 3 to 4 times with charging and using.

3. Does the current of the battery destroy itself?

Chargers are divided into fast charge and slow charge. Slow charging current is small it is usually around 200mA Such as our common charge current is about 160mA. It is a long charging time for NIMH rechargeable battery .Charging 1800mAh Ni-MH battery needs 16 hours. Although time is a bit slow, but the battery will be fullly charged and it will do little harm to the battery. Usually the fast-charge current is 400mA abovet and the charging time is significantly reduced only three to four hours can charge it fully. So they satisfy lots of people. There are many different types and prices of fast charger and we often have questions: why the prices between them is very large? Chargers especially good fast chargers are equipped with the founction of anti-overcharge. Excellent design of chip software can reduce the damage to battery to a minimum when charging them.

4. Does the battery need to keep charging any time?

Although the memory effect of NiMH batteries is small I still recommend you try to use the electricity out before it charged and charge it fully each time not charge it with a short time and then charge it again and again. This would be a serious damage to our battery.

Why the Consumer UAV So Popular?

The history of UAV can be traced back to last century. But recently, with the release of consumer UAV, it is not merely for the upper-class but becomes an affordable "toy" for all the public. The popularity of UAV should be attributed to the joy and operability. When you turn on the aerial photograph mode, you could observe the surroundings through FPV (First Person View), which is a totally new shooting perspective and full of fun. Besides, it is easy to operate and control, especially for the green-hand.
The design of multi-rotor, flying with four or more rotors, is massively adapted into the consumer UAVs, which is the simplest mechanical structure among the three types of aircrafts andis motivated by the motor,and relatively the UAV battery is light weight and long flight time. It has the obvious advantages of simple machinery, being able of taking off and landing vertically. However, the multi-rotor has the comparatively short flight time and less payload.

The quadcopters and multi-rotor UAVS gain the most market, which are lightweight, agile, safe, easy to operate, able to hover in the air and other strengths. The multi-rotor UAVs gradually turned the toy plane into the pragmatic aircraft for aerial photograph. You could see the synchronous picture as long as you connect the UAV with Wifi. Similarly, in the actual flight, you could watch the UAV or the screen. Apart from aerial photograph, the UAVs have been applied in express delivery, disaster relief, patrol, providing network and other fields.

What is the difference between consumer UAV and professional UAV for aerial photograph?

The consumer UAVs commonly have the affordable prices for ordinary people, varying from one hundred to thousand dollars, light weight and operability. For most consumers, the main purpose of consumer UAVs is entertainment. Conversely, to operate the aerial photograph UAVs, people should experience the professional training. Another advantage, especially important for the green hand, for UAVs is that it does not need to assemble by own, which means that we could fly as soon as we buy it.
The aerial photograph is the main function of the consumer UAVs, but it still has great disparity with the professional aerial photograph UAV from the image quality, flight duration, the ability of withstanding bad weather, high-speed of image transmission and other perspective. The professional one could load with professional digital camera, whose image is more clear and has higher pixel. Naturally, the professional one has higher price, from ten thousand to hundred thousand dollars.

In a word, due to the easiness of operate and no need to assemble, the green-hand can control it skillfully after a few practices. And it has a lot of designs of one-touch operation, such as return and land automatically. Also, the price is much affordable for ordinary players.

Why we cannot buy the cheap drone?

It is undoubted that all the UAV fans want to have an own UAV, but the equipment of well-known and mega brand has the price of thousands dollar, which is not affordable for most of players. Therefore, some people will buy the cheaper UAVs, maybe tens of dollars. But is it wise to buy such drones?

To answer such question, the first thing we should clarify is whether we need a better fly experience. The experience depends on multiple factors, and the safety is the most crucial thing. We should choose those qualified products to guarantee safety; however, the cheap UAVs commonly do not have the function GPS stability, resulting in the difficulty in controlling and the instability. When the emergency happens, it cannot hover in time and is likely to cause danger. At the same time, the cheaper UAVs do not have stable holder, which can rotate, so that it could not shoot the steady images. Furthermore, the difficulty for fly improves without the function of image transmission. (It is impossible to see the picture.) Consequently, choosing a safe and stable drone, no matter the price, is wise for all the UAV fans.

Is the multi-rotor UAV easy to operate?

Take Xiro explorer, a quadcopter UAV, as an example; it is mainly operated by the rocker. The left rocker can control the height and direction (up or down and rotate). The right one can control the movement of four directions (forward, backward, left and right). The position can be set manually. The rocker of remote-controller is more sensitive, so we should carefully and slightly operate it to fly stably.

Xiro explorer have the function of GPS emergency hover and making a return. After you choose the landing position, only by pressing one button that it can land steadily. Hint: the landing position should be chosen cautiously. On one thing, do not land on the crowd in case of causing injuries; on the other thing, choose the spacious and smooth place to avoid the damage of drones. In a nutshell, it is easy to operate, but to shoot high-quality image, more time given to practice is needed.

What should be noticed to fly UAVs?

Though it is easy to control and operate, we should know more about the safety common sense, and certainly, the basic operation process. To avoid the air crash due to the power-cut, 14.8V Lipo Battery from Gens ACE is strongly recommended, for it has long flight time, easy to assemble and stability. Additionally, setting the prohibited fly areas is required. The flyers should pay attention to the rules and laws, apart from enjoy the drones.

Some Points of Agriculture UAV

Agriculture UAV ,Just as its name implies,is drone used for agriculture.this type of unmanned aircraft consist of flight platform (fixed-wing, single rotor, multi-rotor) composition, GPS flight control, spray unit,etc .The drone can be used for spraying pesticides, seeds, powder ,and etc through the ground remote control unit or GPS flight control unit,
Generally speaking, Agricultrue UAV is a small remote control agricultural spraying aircraft, can load about 10 kg of pesticides, spraying pesticides at low altitude,Its efficiency is several times the conventional artificial.

The Downdraft generate by the rotor will help increase penetration effect of mist flow to corps, while remote control operation greatly improving the safety of pesticide spraying.
But also it can real-time monitor agricultural pests by carrying video devices.
Small drones have the advantages of low operating height, less drift, can hover in the air , no need of special landing airport, downdraft generated by rotor helps to increase penetration of mist flow to corps , long-distance remote control operation, improvement of the safety of spraying operations, and etc.

In addition, electric unmanned drones can save at least 50% of pesticide used, 90% of water by using Spray spray technique, which will largely reduce resource costs.

Compared with the oil engine machines, the electric powered unmanned aerial have the advantags of small size, light weight, lower depreciation rate, Lower operating costs per unit and easy maintenance,and also Gens ace 2s lipo battery is light,long life,it's more converient to use.

Features:

1. Powered with high-efficiency brushless motor ,can be equipped with precision instruments, make spraying more accurate;
2. Requires few on terrain ,can operate without the limit of altitude .
3. Short takeoff time, high efficiency, high attendance;
4. Environmental, no emissions, in line with national requirements of energy saving and green organic agriculture development;
5. Easy to maintain, use low maintenance costs;
6. Small size, light weight, easy to carry;
8. Featured real time image transmission, real-time monitoring functions.
9. The spray device features a self-stabilizing function , ensure that spraying is always perpendicular to the ground.
10. Semi-autonomous takeoff and landing, when switch to attitude mode or GPS attitude mode, you only need to manipulate the throttle stick you can easily operate helicopter to land or take off smoothly.
11. Failsafe, when the helicopter lost remote control signal ,it can hover , wait for the signal to recover.
12.GPS gesture mode (Standard Edition with no such function, can be get through Upgrade) can make accurate positioning and height locking, even in windy weather, hovering accuracy will not be affected.
13. The high-speed centrifugal nozzle design, makes it not only can control the speed of the liquid spray, but also can control the size of droplets, control range vary from 10 to 150 microns.

Safety Precautions:

1. Stay away from the crowds! Safety must be always in the first place!
2. Before operating the aircraft, make sure that the 22.2v lipo battery have enough power.
3. Fly in the rain is strictly prohibited! Water and moisture may enter the transmitter through the antenna, joystick and other gaps and may lead to loss of control.
4. Fly in lightning weather is strictly prohibited. This is very very dangerous!
5. Keep the aircraft in sight.
6. Keep the RC model and electronic equipment away from children!
7. Stay away from the high-voltage wire!

The Prohibited Areas Of UAV Flight

There are increasing people playing the drones. Although many countries do not have the complete monitor system, some countries have the law to confiscate your drones. As a pilot, the first thing you should know is that flying in some areas is prohibited. Tattu, specialized in the UAV battery, will introduce you some prohibited areas. Hope that help!

1.Airport

Once, the drones interfered the take-off of the plane, and the military helicopters are used to solve this problem. There is no bird in the airport, not to mention the drones. And China has clear law to clarify that the airport and its surroundings cannot have UAVs. The manufacturers have updated their product, which will stop the engine if the symbol of airport has been found.

2.Business district and the crowd

For others' safety, please choose the empty space to fly.

3.High-voltage wires

There is interruption around the high-voltage wires. Though the human cannot feel it, the UAVs cannot stand it. It is common to see the drones fix the wires, but those drones have been refit or custom-made.

4.Base station of mobile phone

Compared to the high-voltage wires, the base stations are often ignored, because they exist everywhere and hard to find. The base station can launch the radio, which undoubtedly interfere the drones. Furthermore, the base station interfere more the remote signal between the drones and the ground, especially the new built 4G base station. It has been proved that the 4G base station has evident interference to the 2.4G remote signal of Futaba, which shows the dramatically shortened remote distance. In cities, we should escape the roof of building where has established the base station. If you notice the dramatically shortened remote distance, please observe whether there has base station.

5.The indoor stadium without GPS

Please choose other suitable place, unless your drone has visual location system which support to fly indoor.

6. Under strong wind or bad weather

The common drones can bear the wind of Level 4-5. Do not challenge your drone in the 5th level of wind.

7. the metal facility.

It has strong interference.

8. military center and government

the restriction varies from country to country. We should pay attention to such information before flying. and also choose a better battery,such as Tattu 22.2v lipo battery,Gensace & Tattu hope everyone enjoys the UAV flight!
