How to Prevent UAV Battery from Exploding?

Lithium ion polymer battery, also called lithium battery is the best choice of consumer UAV. Compared with the model and weight of the cells themselves, its energy density is pretty high, each cell voltage usually is 3.7 volts, so you only need less battery to get more energy than other rechargeable batteries. Lithium battery discharging rate is slow, charging takes a long time.
But use and recharge lithium battery inappropriately, will make the working performance get worse, even causes smoking and burning. In so to avoid UAV battery explode, or make the battery to the best performance use longer, need some necessary common sense. The following Gens ace &Tattu will give some tips are about how to use lithium battery.

Charge the Battery Properly

Use the proper charger to lipo battery and make sure the charger in accord with the battery model. When the battery connects charge, check the device connectivity or whether the battery pins connect fully. Don't leave the charging devices and must be sure not to charge on the surface of inflammable substances, no combustibles around it. In case of fire, fire will spread easily. Recommend using special fireproof lipo battery(3S battery), battery pack, this can control the fires.

Neither too Much or too Little Power

Each battery charging never exceeds 4.2 volts or discharging exceeds 3 volts. In both of these cases, may cause the damage battery permanently. If the battery expands in the process of using or recharging, this shows that the battery has already damaged and can't be used.

Safe Savings

For security, lithium battery should be best stored at room temperature, put in metal box or lithium battery fireproof container. If you will not use a fully charged battery few days, so when placed, must keep the battery power in 40% and each month need to charge and discharge the battery.

Avoid High Temperate and Cold

Extreme temperatures will affect battery performance and life. When you charge, ensure charge at the room temperate. Don't charge in the cold garage or basement. Don't charge in direct sunlight or near heat. When you charge or use lithium battery, be sure charge at the room temperature. If the battery runs out, ensure battery cool down before recharge.

Keep Battery Clean

When the UAV battery getting dirty will affect battery performance. Keep UAV battery compartments and battery connector clean. If battery contact becomes dirty, use soft brush to clean.

Long and Healthy Life Cycle

Lithium battery can use 300 to 500 charge cycles, this depends on the usage frequency of UAV, battery quality and how to maintain. If you only use battery a few cycles and then stop working, this means that these batteries have been damaged, have had defects or poor quality, suggest you stop using it at once.

The tips of UAV Flight safety

At the beginning of 2016, Amazon broke the news that they planning to use UAV distribution. On an interview, they put forward the target of UAV distribution and when the user place an order they hope to be able to complete the delivery within 30mins. With the UAV is more and more popular, at the same time the security and privacy questions are also facing emerging. But I think it is can't stop the more and more hobbyist passion. After all, the UAV application is more and more close to life.

For the most male, when they were young they are crazy the RC car or RC plane. But when they face the UAV really fly ten meters or hundreds meters high altitude, the beginner is not able to get started. Due to lake of experience, and not enough to understand the performance of UAV itself, external environment of the flight is not sensitive and other reasons, it is easy to "crash". To avoid this, I will to share the tips about UAV flight safety.

1. Select the security and widely place

Before the UAV flight, at first, you should to select the security and widely place, high altitude that no obstructions and the terrain is relatively flat outdoor. Don't flight UAV in crowed place, or has the wine, it's dangerous!

2. GPS is OK

When you flight UAV, you should to check the GPS is OK. Because the UAV flight is through the satellite positioning to flight. And for the beginner is also pay more attention to strong air stream.
If the GPS failure sudden, how to do? Don't hurry, most of UAV have the automation return in the system. You just press the button, the UAV return.

3. Control the flight altitude

You'd better to control the flight altitude, under 7kg weight, the flight altitude don't exceeding the 150 meters. If exceed it's need to report the department.

4. Choose the best battery

Most of UAV batteries flight time is 20-30mins, to avoid the UAV "crash" due to the battery is low, you must to choose the best UAV battery, or take more batteries. For the UAV battery, I recommend the Gens ace&Tattu lipo battery, such as 10000mah 6s lipo battery and Tattu plus battery, they have high quality, long flight time and high security, and they also have excellent service.

5. Learn flying skills

In usual, you should to fly with experienced pilot and to seize every opportunity to learn more about flight skill and nervous mentality.

Overall, the most important thing is UAV flight safety, improve the play of UAV technology, and more careful. For security, you have to know how to assemble circuit, wind direction, resistance and other knowledge of UAVs.

Drone agriculture:Fixed Wing or Multi-Copter

How to choose a drone agriculture? Fixed Wing or Multi-Copter? Let's do some simple comparisons fist.

Fixed Wing drone:Ag Eagle

Fixed wing drones like the AgEagle RAPID, and SenseFly eBee Ag are often preferred by farmers because they can spend more time in the air than a multi-rotor platforms like the DJI's Matrice 100.That said, they are best suited for large, open-field scanning.And also Fixed wing drones often carry more payload than a multi-rotor which means more sensors and so more information can be captured in a single flight.

 But Fixed wing drones are more expensive too, usually they cost $5,000 to $25,000 or more after being fitted with sensors.(compare with multicopter)

Pros

Endurance : fly as much as 10x longer and cover more geography in a single flight
Payload capacity: can carry more weight
Applications: larger selection of sensors

Cons

Cost: usually more expensive
Ease of Use: not as easy as a multirotor
Size: requires more space for storage and transport

Multi-Copter:DJI Agras MG-1:

Multi-rotor ag drones like DJI's Matrice 100 are better-suited to precision imaging of small/constrained areas and 3D scanning of fields and objects, due to their maneuverability.
Flight times for quads and other multi-rotors are about 1/2 that of a fixed wing drone.

Payloads on many multi-rotors are less than fixed wings, so most only carry one or two sensors. As a result, covering an entire field can take twice as long as with a fixed wing.
Multi-rotor drones are generally cheaper than fixed wings, starting at around $1,500-$3,500 for a professional-grade camera drone with software for agriculture image processing.

The Best of Both Worlds

Rather than opting for one type of drone, some farmers and operators purchase less expensive versions of both.

A fixed wing drone is used for large open spaces where long, unobstructed straight-line passes are possible; and, a small inexpensive multi-rotor is used for spot-checking trouble areas more closely, for quick scouting missions and for handling area a plane cannot fly over.

Lots of farmers today start by buying a ready-to-fly quadcopter like DJI's new Phantom 4.
After testing the ROI of drone surveying, they may upgrade to more expensive and less time-consuming solutions.

Pros and Cons(Compare to fixed wing):

There are many things that multi-rotor drones can do better, for example, when get into confined spaces,like cross a pedestrian path.they can hover over a specific area, what's more, they need little space to take off and land.

Pros

Cost: Usually more cheaper.
Applications: really good at aerial photography and hi resolution video.
Easy to use.
Can hover,more agile.

Cons

Endurance: less flight time
Payload capacity: usually less weight
Customer service: little support if you are buying a consumer drone
Occasional bugs, is "fly away"

Battery is very important to drone agriculture .Here I'd also like to recommend a very popular lipo battery as below:

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.

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.

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 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.

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!

Can Gasoline Engines Replace UAV Batteries to extend UAV flight time?

Flight time has been a very vexing problem for most of UAV hobbyists. Generally speaking, the flight time for the high end consumer-level UAV is about 25mins; however, the flight time of UAVs for commercial use is not that long.

Many companies desire longer flight time for their own UAVs and are depressed by a constant replacement and charging for the batteries. Most UAVs are powered by the high-end lipo batteries, also regarded as the low energy density battery. That is to say, as to its voltage, the volume of this battery should not be that big. It is unrealistic get a longer flight time for the UAVs by just adding the batteries packs.

After the research and development, Pegasus has come out with a solution of using gasoline instead of using batteries. This company is now having a beta test for the GE-30RangeExtender system, which is a gas-electric hybrid that can be inserted in the battery terminals for most of the commercial- level UAVs. The flight time for the current UAVs is lengthened to 2 hours owing to this system, and it is possible that this system would be used for the bigger models in the future.

The gasoline can bring more energy than the battery according to energy density. A record from the American Institute of Physics shows that the energy of a car filled with gasoline equals to the energy that a thousand dynamite rods can make, and the energy density of the gasoline is 50 times higher than the UAV battery.

In essence, RangeExtender is the two-stroke internal combustion engine that fits for the UAVs though it is not as easy as it sounds. You can not just install the rotors on the grass trimmer to make it fly, or maybe someone has already done this before. Of course, you can make an UAV that looks like a grass trimmer, but that would be a different story.

RangeExtender is a system of gas-electric hybrid made from Pegasus, which can generate appropriate power to wheels, but it is not equipped with electric engine and gas engine as the hybrid electric. RangeExtender is not just mechanically integrated with the UAV but a micro edition of the power system used by large ships. It converts the energy powered by the gas engine into electric power and provides power for the electric motor to make the propellers work.

A good news is that RangeExtender can be purchased in this late summer. RangeExtender would be used by large commercial UAVs. Till now, Pegasus has not mentioned the price, but it has put forward by the MattMcRoberts that RangeExtender would cost far less than $12000 of an annual expense of the batteries for most of commercial UAV operators.
Pegasus is not the first company who's tried to solve the existing problems for the UAV battery. TopFlightTechnologie from Massachusetts has tried to use generator, powered by gas engine, to charge for the UAV batteries. The hydrogen fuel cell provided by the UK IntelligentEnergy can also extend 2 hours' flight time for the UAVs just as the Pegasus system.

Of course, nobody gets cheered by the gas-powered UAVS besides the operators who use commercial UAVs to survey the petrol pipeline or mine. According to the record of US Energy Information Administration, a gallon of petrol could produce nearly 20 pounds of carbon dioxide. The gasoline, maybe, can not replace the UAV batteries but it is a new step forward towards the UAV flight time issues. Grepow is now achieving great success in UAV batteries, and many UAV pilots are getting impressed by its new smart battery-Tattu battery. You may also take a look at the tattu batteries if you're interested in it.

6 WAYS TO EXTEND DRONE BATTERY LIFE

TIP #1: KNOW EXACTLY HOW AND WHEN TO CHARGE YOUR BATTERY

Charging is the Key to extend the battery's lifespan. For getting the best flight time possible, charge your UAV battery right before you're about to use it. "Freshly" charged batteries usually perform better than ones charged several days beforehand. Besides, when you are not about to fly, charge it only 60% of the way and store it in a safe place instead of fully charge it. And, NEVER OVERCHARGE. If the batteries are charging overly, they may ignite or even explode. It is dangerous and also detrimental to the battery's lifespan.

TIP #2: DON'T ALLOW YOUR BATTERY TO COMPLETELY DRAIN ITSELF

Each time that you do this, you slowly wear down the lifespan of the battery. It is recommended that you fly your quad copter with no less than 3.5V. Once it dips to 3.5V, stop flying and give the battery a rest, then charge it for use next time.

TIP #3: AVOID THE STRONG WIND

When you fly your quadcopter in strong wind, your motors have to produce more thrust to maintain the flight, which requires more power conducted by batteries. Therefore, it is highly recommended to fly in a good weather or low wind.

TIP #4: CHOOSE A CONSERVATIVE FLIGHT MODE

Nearly all RC drones come with various "Flight Modes" that you can switch by simply putting a button. The aggressive mode increases transmitter sensitivity and consume more electricity. Conversely, flying more conservatively consumes the power more slowly with a lower sensitivity. Try to fly conservatively when you are not racing!

TIP #5: LIGHTENING YOUR EQUIPMENT

Since the battery discharges faster while recording and shooting, you can turn on the camera and even remove the camera (if it is detachable) to slow down the pace of discharging. This may be helpful of prolong the battery's lifespan.

TIP #6: BUY EXTRA BATTERIES!

The flyers are now purchasing more batteries, for use or for backup, to maintain a long flight time for their drone. Generally, spare batteries can be accessible easily and can be purchased on sites like:
genstattu.com
These tips can make sense in extending the battery's lifetime, but it is unrealistic to double the flight time. SO, taking good care of the gens ace 2s lipo battery and using it properly.

The LIPO Battery is heart of UAV

The full name of the battery used in the aerial photography is called Li-polymer battery (also known as high molecule lithium battery) and Li-battery for short. Li-polymer battery is a new-type battery and has the obvious advantage of high density, small size, ultrathin, light weight, high safety, low cost and so forth. These years, the aerial photography, using UAVs,the UAV Battery comes to the public. Its irregular shooting perspectives, convenient operations and simple structure have gain the applause countlessly from video creation organizations, and even this technology has stepped into the ordinary families.

At present, the mainstream of UAVs aerial photography are multi-rotor, helicopter and fixed-wing. According to their structure, the fixed-wing can fly for long time, but the fixed-wing demand highly skill of taking off and landing on. It could only be used in the mapping and other fields which do not require high image quality, since it cannot hover in the air. However, although the multi-rotor and helicopter have comparatively short flight time, as the most types of aircraft in the video creation, they can take off and land on the complex terrain, fly stably, hover, strong ability of wind resistance, be easy to operate. These two types of aircraft mainly use the battery to provide power, and helicopter can use the gasoline-drive engine as well. But people reduce the use frequency of gasoline-driven engine due to the mechanical vibrate and the more flight risk. Naturally, the usage of battery spreads widely in the UAVs photography. A team prepares at least tens of any sort of batteries. The batteries provide power tirelessly for the motor, electric regulator, flight control, OSD, image transmission, receiver, remoter, controller and other electric parts of the aircraft. In order to fly well and safe and shoot successfully, it is reasonable to know the parametric of battery, usage, maintenance, charge and discharge and so forth. And now, let us know more about the battery, the crucial part of aerial photography.

From its shape, Li-polymer battery has the characterization of ultrathin, which could meet the need of any product, produced into any shape and any capacity. The external package is made of aluminum plastic. Being different from the metal case of liquid li-battery, the internal quality problem can be presented in time from the distortion of the package, such as bulging.

Let us move to the basic parametric of battery. Take 22.2V 10000mah rc lipo battery as an example; six Li-cells, which has the rated voltage of 3.7V, capacity of 10000mah, are put in series to form the battery. In other words, the 6S1P and 6S2P battery is formed of 12 5000mah lipo battery in series and in parallel. To be more specific, 6S1P is more safe than the 6S2P, because the 1P has more simple structure than 2P and more expensive.

Among the Li-battery of model, the rated voltage of single cell is 3.7V, which is gained from the average working voltage. The actual voltage of single Li-cell is 2.75-4.2V. The capacity labelled on the Li-battery is the voltage which discharges from 4.2V to 2.75V. Li-battery should be used in the range from 2.75V to 4.2V. If the voltage is below 2.75V, the battery is recognized as over-discharged, and the chemical liquid inside will crystallize. The crystallization may puncture the inside structure layer and cause short circuit, even change the voltage of Li-battery to zero. During charging, it is deemed as over-charged if the voltage of single cell is above 4.2V. The inside chemical reaction is too much fierce, and the Li-battery would bulge and then burn if charge continuously. Therefore, it is a must to use the formal chargers which conforms with the safety standard. Besides, self-refit is prohibited since this may cause serious consequence.

Cautions: Do not use the single cell of aerial photography power battery to 2.75V, because this battery cannot provide the effective battery to aircraft. To guarantee the safe flight, the single warning voltage can be set as 3.6V.
