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 It appears the same when completely charged or empty, new or outdated and in have to have of replacement.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.

How To Extend Your Drone Battery Lifespan?

With the high science and technology development, the price of drone is lower and lower but it’s more and more advanced. However, there is a big problem-battery lifespan all hobbists face when flying drones. To all the batteries and drones manufacturers surprised, the short lifespan problems caused mostly by the pilots careless and ignorant management, and have no idea about how to protect and extend the batteries lifespan.

Then how to extend your drones battery lifespan? Here we go:

TIP 1: Never overcharge your battery

Lipos (the types of batteries on most drones) are serious business. They are highly volatile, prone to damage and can cause fires. Despite highly responsible ownership, a lipo battery is still thought to be the cause of a fire that burned down an RC shop in San Diego, and numerous videos show other accidents involving lips. And fire caused when they are charging without paying attention to its charge state.If you let them alone to charge for a long time, it’s likely that they can explode and result in a fire. The first stages of overcharging will cause your battery to puff up, become swollen or otherwise misshapen. If your battery appears puffy, responsibly dispose of the battery immediately.
So overcharging is potentially dangerous, and also do harm to your drone battery life extremely. So never over charge them till spontaneously ignited, then all things will get terribly horrible.

TIP 2: Charge your battery in time

You can’t let your battery drain automatically without any care and charge your drone’s battery right before you’re about to use it. It can ruin your battery when has empty capacity for a long time. So even you won’t use them for a long time, you need to charge them periodically. But don’t fully charge the battery. Instead, charge it only 60% of the way and store it in a safe place. Then, when you’re ready to fly, finish charging it to maximum capacity.

At the same time, you need to get a good charger which fit your battery a lot. Charge times tend to be relative to the capacity of the battery. You can shorten charge time by using a charger with a higher output, which is indicated by amps. For example, the DJI Phantom 2 charger is 2 amps and it will take 1h to 1.5h to charge the battery. Using an aftermarket charger that charges at 6 amps would cut down the charge time by over half. Proceed with caution when charging your drone battery.

TIP 3: Get seperated drone battery

This tip why it’s better to get seperated battery for your drones is because that even one battery damaged or worn, it doesn’t have an impact on the other batteries. Then it will reduce losses cost and protect your drones better. This will in other way to extend your battery lifespan. Obviously that many drone makers including DJI and Yuneec have recently started using seperated “Smart Batteries” for their drones, which can not only meaning every battery is respectively seperated, but also display remaining battery capacity. Additionally, power management is handled internally so the battery doesn’t require a separate balance lead to control charging. Tattu Smart battery is highly recommended to you.

Tip 4: Choose a larger capacity battery

Most drones will equipped with a lower or mid capacity battery to reduce the cost in that drone. These batteries usually do not offer a long flight time or are made up of good high quality rechargeable cells. So we recommend to go at least the next higher or two steps up in capacity in your drone than what was supplied originally. However one thing to keep in mind here is to pay attention to the weight of the battery and make sure to not add to much weight.

Tip 5: Reduce the whole drone’s weight

You can install the camera to the drone when it is needed. If you are just flying your drone to enjoy it and not trying to capture any video then leave the camera off. The camera will not only add more weight but it also drains the battery due to it needing to be powered to run. And the reducing weight will reduce the harm when drones fall down.
The above tips for protecting battery life and drones are very important to us, or the battery is easily damage or dead in a short time. And buy a good quality brand like Tattu(14.8v lipo battery), Bonka or Turnigy is very important to have a longer lifespan.

Consider You To Insight Into the UAV Terms

Are you currently occasionally truly feel puzzled when see some good nouns about UAV? Do you actually get what they imply at some point? Now we'll take some pretty regular UAV terms to explain and fully grasp them deeply.

UAS

The phrase UAS(unmanned aircraft process)includes the drone and any ground and remote programs which can be utilized to control the flight in the vehicle which include software programming.

Drone/UAV

A drone or perhaps a UAV(UAV BATTERY),which stands for Unmanned Aerial Automobile,can be created from the form of the helicopter,an airplane,or multirotor.So,by well-liked terminology, any automobile that flies and doesn't possess a pilot inside the cockpit manually steering it would be a drone.It may very well be managed by a human by way of a remote or by pre-programmed laptop application.tend to be favored for missions which might be too"dull, dirty or dangerous"for manned aircraft.They have and are mostly found in military and unique operation applications. Even though,UAVs are increasingly discovering utilizes in civil and recreational applications,this kind of as policing and surveillance, aerial filming,and drone racing.Often,UAV is the very same meaning as drone.

Helicopter

A helicopteris a kind of rotorcraft in which lift and thrust are provided by rotors.This allows the helicopter to vertical take-off and landing(VTOL),and also to fly forward,backward,and laterally.These attributes permit helicopters for being employed in congested or isolated places,which suggests that it doesn't have higher requirement on the working spot.It could be controlled by a human by means of a remote or by pre-programmed laptop computer software.

Multirotor

A multirotor or multicopter can be a rotorcraft with a lot more than two rotors.An benefit of multirotor aircraft would be the easier rotor mechanics demanded for flight manage. Contrary to single- and double-rotor helicopters which use complicated variable pitch rotors whose pitch varies because the blade rotates for flight stability and management,multirotors usually use fixed-pitch blades;manage of vehicle movement is accomplished by various the relative pace of every rotor to change the thrust and torque developed by just about every.

As a result of their ease of the two development and manage,multirotor aircraft are commonly made use of in radio management aircraftand UAV projects in which the names tricopter, quadcopter,hexacopter and octocopter are frequently used to refer to 3-, 4-, 6- and 8-rotor helicopters,respectively.

Fixed Wing Aircraft(Airplane)

A fixed-wing aircraft is definitely an aircraft,such as an aeroplane,which is capable of flight using wings that generate lift induced by the vehicle's forward airspeed and the form with the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft,by which the wings type a rotor mounted on the spinning shaft,through which the wings flap in equivalent manner to a bird.Fixed-wing aircraft's landing and taking-off demands much more open field.

FPV

First-person view (FPV),also called remote-person view (RPV),or just video piloting,can be a method employed to regulate a radio-controlled vehicle from the driver or pilot's view stage. Most frequently it is utilised to pilot a radio-controlled aircraft or other variety of unmanned aerial motor vehicle (UAV).The vehicle is either driven or piloted remotely from a first-person standpoint by means of an onboard camera.When use FPV(FPV battery),the perdon will put on a pair of committed glasses,and people can see the view simultaneously from the camera inside the FPV.
All above UAV I stated are electric but not fuel variety,so they require battery to support for functioning.The battery I choose is gens ace 2s lipo,whose high-quality and service is exceptional.Have a consider,my friend!

What Equip Was Used At First Taiwan FPV Racing Competition?

Taiwan ford environmental restoration park host the first ever FPV racing drone contest, this FPV is different from the well known aerial photography UAV. FPV drone is more focus on racing, and is operated by the first-person perspective screen through the OSD Monitor system which is more realistic than a flight simulation flight game. Gens ace here ,brand from a famous LiPo factory will bring us report after the game:

What is FPV?

FPV, full name: First Person View, but generally refers to the FPV that is a first person perspective UAV(UAV battery). And what it differ from the general speaking Aerial Photography UAV (which is more focus on stability and the ability of photographing) is that FPV is more in pursuit of flexibility, speed and flight experience.

FPV is divided into fixed wing and multi-axis vehicle, although the former originated earlier,but the latter gradually began to develop in recent years, foreign countries also started some multi-axis FPV drone racing, although in Taiwan it is not yet universal ,But there are also a lot of amateur players in China, and these lovers gather together to hold the Taiwan’s first FPV drone racing contest.

Competition System

Since it is the first FPV drone racing in China ,so many rules and the system is still in groping, but generally it’s referred to other countries FPV competition regulations. The Competition adopting Circuit, a total of three times bypass, four participants ,they must bypass two main green bars obstacles, and pass through the four limit high arches,if does not get through arch,it will be required to fly again.And then elect the champion through semi and final champion.

The reason why FPVs don’t take off together is to avoid mid-air collision, the second aspect is to avoid radio frequency interference, as some times the FPVs do not response(like just lie on the ground,can’t move), and also remote control device around the site will interfere , for example, frequency interference from remote control cars, remote control vessels.
The game take place at an altitude of about 150M, Mucha - Taiwan Hang environmental restoration Crawford Park, the venue is quite open for the FPV racers to fly with few limit.

Unique gameplay

Before playing FPV, first you need to know that FPV drone players crontrol the FPVs by a first-person perspective of the Monitor (or glasses), instead of looking at the body to control it. Why play like this? It’s because the body of PFV is quite flexible, when carrying around a cone or turning flight, it is difficult to distinguish the state of the fuselage and flight attitude, and therefore it must be a first-person perspective to control the body.

Such feeling is somewhat similar to play first-person perspective flying games, therefore, FPV players in the game are all looking at the screen , a group of people take with a chair each one, and with a display screen set on the grass, the players will watch the screen to concentrate on operating the remote control, it is probably a major feature of the FPV game.

FPV kit

 

Currently FPV players mostly used their own DIY FPVs, in order to fly stable, fast and flexible, specific accessories include: FPV drones, remote control, Monitor, or glasses, FPV battery ,etc. But the cost is not as much high as imagine, single frame need about five thousand, and the cost of remote control and Monitor Level depends, about 20,000 you can play the game,but it’s not enough for these DIY Makers , camping chairs, sunshade ,and the like are also needed.

Four things you need to know to start FPV racing

FPV drone racing has become a very popular activitiy recently worldwide.There are many asks about FPV drone racing. Here I will write a article about some things you need to know to start FPV drone racing.

Start Transmitting Video&Video Camera

There are pretty much options for frequency choice but the most popular one for newbies is 5.8Ghz. It easy to get start an have fun without getting into trouble. 5.8Ghz has many nice channels to choose and you can buy a lot of different FPV related items for this frequency.Most FPV cameras available today are primarily from the video surveillance & security industry and work very as well for FPV due to the small size and good low light capabilities.If you are afraid of soldering or getting your wiring well connected then you can buy a all in one unit. These are video cameras with built in FPV transmitters .

Some famous FPV cameres:RunCam 2 Full HD Camera,SONY CMQ1993X HD Camera,etc

Select Your Video Transmitter

There are a lot of video transmitters available on the market today each with its own frequency,antennas and etc.
You should know not more power is better ,too much power can interfere not only with your gear but your friends signal too if you are flying in with friends. I suggest you start with with 25 to 200mW video transmitter.

And you should know FPV video transmitters are not your 2.4Ghz RC transmitter. They can’t frequency hop. You need to set the video transmitter to a channel and make sure the video receiver are in the same channel. If anyone else if flying FPV you have to make sure you aren't on their channel!

A good antennas is very important

Your FPV system is only as good as your antennas. Most start using what comes with most video transmittersand receivers.a simple omni directional linear polarized whip antenna set which, depending on your frequency, can give very poor performance.

Practice&fly safely

When flying a FPV drone, the pilot sees from the aircraft's perspective, and even not need to look at the FPV drone. So the FPV aircraft can fly well beyond visual range, it’s only limited by the range of the remote control and video transmitter.

Where is it safe to fly FPV? I would hope that most people would agree it’s dangerous that flying over largely populated areas, busy highways, and other areas of high population density,especially for beginners,you should choose a sparsely populated areas.Parking garages and forests are also perfect venue?for drone racing enthusiasts.So first make sure you get a proper FPV and good place to fly,then take someone with you who’s experieced with FPV racing.Do not attempt to fly 2 miles away from yourself, with headtracking, in high winds, near sunset, on your very first FPV flight! That is of course an exaggeration. However, FPV flying is entirely different than line-of-sight flying. You get a completely different perspective, and during your first flights, it is very easy to become disoriented. it takes practice, practice, practice.

Suggestions

I used voltage alarms on my planes and on my goggles. Losing power is not good and neither is ruining a 14.8v lipo battery.Tattu 1300mah 75c 4s ,this is maybe the most popular battery for FPV racing recently.

I suggest you to learn from someone who’s experienced with flying FPV. It will make you learn faster, easier and have more fun.
Fly safely!!This is the first principle!
Have fun!

The differences between Smart Battery And Ordinary Battery

The DJI new-released M600 brings big breakthrough to the all UAV Area. Not only the A3’s self-adaptive flight systems and new RONIN-MX is , but also the pretty long flight time supported by six smart batteries.
It introduces that a customized battery management system and power distribution board allows all six batteries to be turned on with one button press, and keeps the system in flight in the event of a failure of a single battery, and allows users to check the battery status in real-time during flight.
As we all know, M100 has adopted smart batteries to support the big heavy device for more professional aerial photography and longer time and distance using. Then what are the differences between Smart Battery and Ordinary Battery, why they are more and more widely used in the electronic ndustry?

1. Definition

A smart battery/A smart battery system(SBS) is a rechargeable battery pack equipped with a built-in battery management system. The smart battery can internally measure voltage and current, and deduce charge level and SoH (State of Health) parameters, indicating the state of the cells, calculated and predicted information to its SMBus Host under software control.
A basic SBS including 3parts:System Host,Smart Charger and Smart Battery.

1.1 Advantages

Ordinary Battery

Ordinary Batteries are illusive and do not exhibit visible changes as part of usage from both the user's and the equipment's perspective. It looks the same when fully charged or empty, new or old and in need of replacement. A very big defect is that they represent an unpredictable source of power.

Firstly, a user has little knowledge that their battery is about to run out or how much operating time is left.

Secondly, equipment powered by the battery cannot determine if the battery, in its present state, is capable of supplying adequate power for an additional load (such as spinning up a hard disk) or not.

Smart Battery

The Smart Battery presents an ideal solution for many of the issues related to batteries used in portable electronic equipment.
The Smart Battery provides the user with accurate state of charge information along with an accurate prediction of the remaining operating time.

It also Provides state-of-charge and full charge capacity; reflects capacity estimations; records battery history; including cycle count, usage pattern, maintenance requirements, max error, etc; configures charger to the correct algorithm; reminds user of periodic service; protects 7.4v lipo battery from unauthorized use; and to prevent accidental system cut-off.
This is why smart battery is more and more popular and widely used.

An excellent smart battery brand-Tattu plus, also have all these advantages when using on your drones.

1.2 Charger

Ordinary Batteries chargers : It must be individually tailored for use with a specific battery size and chemistry and may cause damage if used on another battery.

Smart Battery Charger: It periodically communicates with a Smart Battery and alters its charging characteristics in response to information provided by the Smart Battery（2s 7.4v lipo battery）.

1.3 Defects

The Smart Battery will add 25% to 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.Requires periodic calibration.
Compared with the Smart Battery’s disadvantages, it has more and valuable features.We believe in the future, people will creat more progressived technology on Smart Battery and overcome the price and other problems step by step.

Choose Helicopter,Airplane or Multirotor ?

Multirotors are very popular these years after DJI economic and recreational multirotors’ coming.And they attract many newbies to the RC Hobby and UAV areas.But many new beginners express that they are confused to choose heli,airplane or multirotor as a beginner.About how to work,we have posted in the last article(http://rclipobatteries.blogspot.com/2016/04/take-you-to-insight-into-uav-terms.html）,and they are still quite different in many aspects,now we will compare them in some important ones.

In Operability:

In terms of the operability,multirotors are the simplest cause their rotors can change the thrust and torque produced by each.They can fly with no need of runway,and hover after taking off.So it can help to observe one object for a long time by hovering in the air.
However,the airplane’s(Fixed-wing aircraft’s) landing and taking-off needs more open field.
And the helicopter can VTOL in congested or isolated areas,but its drive device controller design is difficult,and the controller adjustment is also very difficult.

In Reliability:

When it comes the mechanical reliability,multirotors don’t have movable parts,it basically depends on the reliability of the reliability of the brushless motor, so the reliability is higher.In comparison, the airplanes and helicopters have mechanical connection parts,they will wearing out in flying and lead to a decline in reliability.And multirotosr can hover,which means that the flight range can be controlled easily,so they are safer than airplanes.

In Stability:

Helicopter’s stability is weakest.Many of the simplest helicopters don’t require advanced systems to be pretty stable.
Airplane’s stability is better than helicopter,but its speed is fastest.
Multirotor’s stability is strongest.A multirotor has 3,4,6 or 8 different motors in its shape.You can control the rotor blades to perform all sorts of aerobatics and tricks.In most cases,multirotors are more stable than helicopters and airplanes.The stability means that the machine is able to perform and keep performing an instruction commanded by the remote control until other instruction is transmitted.
The higher the stability the easier to fly.

In Application:

If you intend to transport something,such as a camera or another mid-weight object,then a multirotor is for you,not just because of the above advantages but also because they have a bigger body.Many amazing videos online about high buildings,wonderful landscapes,and crazy aerobatics were filmed using one of these.And multirotors can be using in more areas like investigation,plant protection,monitor the?situation, rescure in emergency and so on.
A helicopter may get balanced to one side and that would affect the center of gravity, altering the entire functionality of the device.But its flexibility is best cause the small body and responds quicker than the others because there is only one or two motors that need to be adjusted when sending a command.It is more common to see RC helis doing all sorts of maneuvers and tricks.A very exciting vedio shows RC helicopter mops the floor and wall use its rotor blades.

If you want to choose one machine who has fast speed,fly in long distance and longer time,then an airplane is better for you.But because it is hard to controll and work,it is not common used yet.

In Your Expertise Level:

If you have very little or no experience with RC flying devices,you can choose RC helicopter to begin your hobby because RC heli works with easier channels when compare to the other two.Multirotors have more complicated channels and function you need to control.And Airplane is the hardest one and not very common nowaday!Definitely,it’s more fun and you will get great flight experience when flying multirotors.

In the Budget:

In the past a multirotor is much more expensive than a RC helicopter,certainly,airplane is most ecpensive.But with the time this has changed and now you can get a great quality multirotor in a pretty reasonble and affordable price for many.However,you need to think of spare parts when choosing one of these machines.Please don’t care about the price merely when purchasing the first device.Do be care about the spareparts and check the important parts price like motors,battery,rotor blades and so on to make sure you can get them easily when needed to change.In general,the budget spent in a multirotor will be higher than a RC heli because of the big body.The most normal budget is that multirotor will need bigger capacity battery than RC heli.So you need to choose a reliable brand to use.I prefer Gens Ace 2s lipo and Tattu rc car batteries lipo battery whose quality is excellent in a good price.

From all the above analyze and comparison,now it’s up to you.Choose which one Multirotors,RC heli，or Airplane,it depends on yourself. No matter which kind you choose,I believe you will fall in love with them and enjoy yourself greatly.

To understand a Multirotor

Frame is the core of a multirotor, almost all the accessories connected to it directly. We can put the whole model aircraft into two parts: a "heart" - flight control and the use of motor control "legs" - machine blade, and above all these parts are to be integrated in the frame, in order to avoid damage by hitting them, and a rack and control center of gravity of the whole plane.

So what the material usually use to build a frame?

Frame can be made up of many different materials, such as wood, plastic, metal (aluminum), glass fiber, carbon fiber, and other materials. All the parts will be fixed with screws or cable tie on the rack, and occasionally see a flexible foam padding on the rack with plastic or similar in order to reduce the impact of external factors on the frame buffer.

How to define a multirotor?

There are two mainly aspects, the definition of the element is the number of the motor, it defines the number of rotor how much N; 2 it is rack wing (axis) M, the number of that defines the aircraft is M shaft aircraft. We usually of a spacecraft called M axis N propeller aircraft.

Tricopter（3-motor)

Tricopter generally has two axis in the plane forward, a shaft in the negative. So the body should looks like T or Y type. Negative motor adjust plane through the rotation of the fixed on a course , tricopter is better control, usually also rise faster, but not dramatically. Of course, if the motor stops operation, so the plane will crash, but this kind of model is relatively agile.

Quadcopter（4-motor）

Quadcopter weight more than a tricopter, were also more likely to form, because the quadcopter does not need to separate to control the parameters of single motor. They are more stable, and the flying time is longer, because you can carry a bigger Lipo battery 5000mah. quadcopter by reducing the speed of the two motor to implement the roll, and the other two motor can control the whole of the aircraft.

QuadcopterX(QuadX) or quadcopter+ (Quad +) has different wingspan, makes the plane looks like an X or a +.

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

The basic design of hexcopter and octocopter are same. Rotor arranged around a central point into a round shape. There are some model install the rotor at the top. Y type hexcopter looks like a tricopter, but no one in which the parameters of the rotor independent control. On the contrary, yaw is similar to the four rotor aircraft, by changing the speed of the motor. Compared with the independent design yaw rotor, such design feeling not sensitive compared with independent yaw.

More rotor enables the vehicle to load better and more stable. Under the control of the rotor more aircraft in flight controllers, when one or more of the motor power, still can keep the ability to fly without crashing. But of course the total weight of aircraft and its complexity of building and is proportional to the price, and the number of rotor also need a lot of power supply,also need more 5000mah Lipo-batteries 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.

The best thing is not to start from a finished product craft. Firstly because when you crashed some expensive equipment, you have to wait and spent a lot of money go to the factory repair. Secondly, finished aircraft heavier commonly, lightness of equipment is easier to control when flying in the air. Thirdly, when flight control automatically upgrade and programmed by manufacturer, after it has already prepared everything for you, and you will never feel yourself the fun of how rotor aircraft flight control. The order we need to study is to grasp the principle and properties of aircraft first, and then to the next step of assembly and manipulation.

The battery grow to be necessities of life

An electric battery is an energy conversion and storage units that convert stored chemical power into electrical vitality?

With the speedy formulated science and engineering, improvement of human residing standards, much more and even more variety of new options, high-tech electronic merchandise are extensively used to people.Correspondingly,it's going to market the arising of all sorts of various visual appeal and performance batteries.
The huge brand such as Nanfu battery,GP battery,Panasonic and so forth are identified by people today.Yet another two significant brands have attracted around the world focus with their fantastic good quality,innovative design and performance-Grepow and ATL.

Shenzhen Grepow Battery Co.,Ltd is a expert R&D,design,manufacture and selling company.From the establishing year 1998,Grepow has changed greatly in its development.

Grepow manufactured and supplied Ni-Mh battery from 1998 in a large quantity with its stable excellent,reasonable price and perfect service.It is actually a kind of no-pollution,no cadmium new green power battery extensively utilized in areas like civil daily life,cars,toys, telecommunication and so on. We recommend NiMH for applications where a device has already been designed to use AA type batteries.

This batteries, however,have a short lifespan,heavy,low discharge rate,and low voltage characteristics,so Grepow update to manufacture 5000mah Li-po battery from about 2009.

With a professional R&D team,and extensive experience in manufacturing battery, fantastic technical documentation and advanced processing management system,Grepow's 2 major brand Li-po battery-Gens Ace and Tattu are greatly identified and used in RC ans UAV.which ensures battery's consistency and stability in mass production.

Gens Ace batteries are very useful for embedded electronics. They offer the highest density readily available on the market. Because cell phones predominantly use this battery type, they are easy to find for reasonable prices. They do require special charging, so be sure to use the right charger for the job.

Gens Ace LiPo batteries cell has a nominal voltage of 3.7V(lipo 3s voltage). When fully charged you will see nearly 4.2V on the cell but it can quickly drop to 3.7V under normal use. When depleted, the cell will be around 3V. This means your project will need to handle various voltages if you are running directly from a cell. If you need 5V you will need to combine two LiPos in series to create a 7.4V pack and regulate down to 5V.

We recommend Gens Ace LiPo for nearly every portable application like helicopter,RC,jump starter and so on.They are fairly robust and when employed safely provide a great power source.

DJI-the world market leader in easy-to-fly drones and aerial photography systems,adopts Grepow's Tattu battery to control its famous UAV.With all the advantage of experienced R&D, humanized service,mass production capacity,amzing explosive power,Tattu is widely made use of by other significant brand GoPro,Panasonic,LG and so on.

In the future,Grepow's Tattu will be applied in a lot more fields and Grepow will pay awareness and be allergic to more potential development trend and supply better bettery or other amzing products to the world.

Battery packs achieve the desired operating voltage by connecting several cells in series; each cell adds its voltage on the total terminal voltage. Parallel connection attains higher capability for increased present handling; each cell adds to the ampere/hour (Ah) count.


The nominal voltage of a Li-Po battery cell is 3.7V (about 4.23 V when fully charged). Two and three cell batteries are available giving us a choice of 7.4 or 11.1 volts. Li-Po batteries can provide substantial present, 6A continuously and 12A 5000mah lipo battery for short (30-second) bursts. Li-Po cells have a flexible, foil-type (polymer laminate) situation. Since no metal battery cell casing is required, Li-Po batteries are very light. Because from the absence of metal casing and less space utilized in intercell spacing, the energy density of Li-Po batteries is over 20% higher than that of a classical Li-ion battery and store more energy than nickel-cadmium (Ni-Cd) and nickel metal hydride (Ni-MH) batteries in the similar volume.


Many radio-control enthusiasts experience disappointment using the cycle life of their Lithium-based batteries in electric aircraft. Often this is because they're not entirely sure what's going on inside the cheap lipo RC batteries, and choose a capability or voltage that's inappropriate for their application. Ultimately, this manifests itself in swelling or ballooning of a Lithium battery. This editorial attempts to explain what's actually going on when this happens.


If you plan on using rc car batteries lipo packs for your DIY Electric Skateboard Build. There are a few large quality RC lipo battery which I highly recommend as well as a few cheaper options as well.


That's about it for this portion .Hopefully this function will help you appreciate and get the very best from your batteries and uavs!So go and to choose the correct voltage(2S-6S) and size(physical dimensions) to match in your motor vehicle!

How to choose the best Lipo battery for FPV

Does Larger battery allows for longer flight time?
Unfortunately the increase of flight time isn’t proportional to the increase of battery size.As the battery gets larger, the increase in flight time becomes ineffective. Eventually it will reach a point where it just doesn’t gain any more flight time with bigger battery (even lose flight time). This is mainly caused by the weight of the battery. Also note that the heavier your copter gets, the less agile it will be.
There are techniques you can use to help with selecting FPV battery – creating graphs and mathematical model in Excel,
which I found really useful when comparing various products of the same kind. I recently bought some 4S batteries for my FPV quad , like Turnigy Nano 4s batteries and Tattu 4s batteries
I will use these as an example. This technique should be useable for any multicopters, including the 250 mini FPV quad.

List All Batteries and Create Graphs

First, list all the batteries with different capacities, brands of the same cell number. You can include their weight, price, etc in your table. For example I was looking for 4S lipo battery for my FPV and here is the table I created.

Listing batteries and data

From these data, you can create some very interesting and useful graphs, for example I usually do
Density, which is capacity per gram (= capacity / weight)
Value, which is capacity per dollar (= capacity / price)

From the above graphs, if I am only going for best performance and not worry about the price, I would definitely go for 2650mah, 3000mah, or 3300mah FPV batteries.
These graphs tell you some insights into which battery has the highest price/performance ratio, but it doesn’t tell you whether this is the best battery for your RC aircraft, quadcopter or tricopter. To do that, we need to create a mathematical model.

Build Mathematical Model to Estimate Flight Time

By using this model, you will be able to calculate the flight time of any battery. Of course, this is just an estimation, but it will give you an rough idea what battery to go for, and save you from spending too much money and time to try each type.First of all, you need to get one battery first, and collect data using it. Basically the data we need is flight times under different loads. You can collect some other data as well to help you identify what is the max load your FPV can take, for example, the throttle value, current etc.
For example, I used a 3s 2200mah lipo battery, and tested the flight times under different load weight (0g, 110g, 220g, 340g, 405g, 515g – all these weights are physical items I can find in the house that’s why the uneven numbers). This as below is the data I collected from 6 test flights.

I always land the FPV when the voltage alarm beeps, which is when the voltage reaches 3.5V per cell. The column “Actual Capacity Used” is not really needed, but I collect it just to make sure my data is valid. I got that from my charger, when I charge it fully at 4.2V per cell, I know what capacity was used in the previous flight.?I then work out “mah / second”, which is the speed of power consumption, and we can draw a graph from this.

So here is the model. “Cap at 3.5V (86%)” is the effective capacity that can be used during a flight.?I am making an assumption that the voltage drops down to 3.5V when 86% of battery capacity is used. “mah/s” is calculated from the above equation, we can work out the mah/s for each FPV battery, depends on their weight.

And now the estimated flight time is roughly equals to effective capacity divide by mah/s. For example for the 6000mah battery, the effective capacity is 5160mah, and the speed of power consumption is 5.75mah/s, so the flight time would be 898.16 second which is nearly 15 mins.

That’s the analysis I always do when buying FPV batteries. There are a lot of assumptions above, so also do your research on the flight time, ask people for their experience, to verify your theory.

Tips for the model lithium battery store

Model lithium battery has the characteristics of the high capacity,high rate and discharge ability strong,and has been widely used by more and more model race enthusiasts.because of this characteristic,the model battery storage will need certain conditions and methods,to avoid battery damage.store the model lithium battery,gens ace 2 lipo (TATTU) tips and made some caveats:

1.model lithium battery stored voltage

Model lithium battery is general a Li-po battery,the safe use of the lowest voltage is 3.6V,but in order to ensure that the battery will not damage due to excessive discharge,the lowest minimum security value using of 3.7v,the highest charge cut off voltage of 4.2v.The highest voltage, battery energy storage for peak,if maintained for a long time without the use of high voltage, lithium-ion cell drum up, in order to avoid the occurrence of such a situation, the model lithium battery storage voltage control in general 3.7 ~ 3.8V.

2.Lithium battery storage conditions

Model lithium battery storage condition is the most critical temperature and humidity,there can not direct sunlight and high temperature easily lead to explosion or muster;so that,the battery will be stored to avoid light lithium tin or plastic box,if a single model of lithium battery discharge performance is very good, also need to purchase a model lithium battery explosion protection bag, this kind of strengthening bag internal net, can prevent high-energy lithium battery explosion in the event of a leakage model cause harm to other items.

3.using the model lithium batteries after storage

Lithium battery self-discharge is very small, when stored models of lithium batteries don't need to be activated,usually when restart, can be directly connected to the charger power charger. but in order to be sure, every time before restart, had better use multimeter measure the total voltage of model lithium-ion batteries, lithium battery storage for a long time,voltage may be lower, at about 3.6V（2s 7.4v lipo battery） are safe.

Serial or Parallel connection for your RC models/Drones

Many of you want to increase your RC models/Drones speed or playing time ,and find a way to increase the voltage or capacity.Exactly,through connecting several cells in series,battery packs achieve the desired operating voltage.Each cell adds its voltage to the total terminal voltage.Parallel connection attains higher capacity and the same as current handling.Each cell adds to the ampere/hour (Mah) count.

Serial Connection

One battery’s positive connects the next battery’s negative and all connect like this.In this way,the voltage increases,but the capacity unchanged.That is to say, the total voltage is the sum of all series batteries voltage.

Connecting a pair of 1s, 3.7v, 5000Mah LiPo's in series:

This will increase the VOLTAGE x 2,but the capacity will remain the same for a result of 7.4v,5000Mah lipo battery.

RC models/Drones needing higher voltages,use battery packs with two or more cells connected in series.The advantage is that you can increase the speed of your RC models/Drones.But high speed for a long time will shorten the battery lifespan,so take care and operate in an appropriate speed.

Parallel Connection

One battery’s positive connect the next battery’s positive and negative connect negative,all connected like this.The voltage is unchanged,but the capacity increases,correspondingly,the current also increases.

If higher currents are needed and larger cells are not available or do not fit the design constraint, one or more cells can be connected in parallel. Most battery chemistries allow parallel configurations with little side effect.The voltage of the illustrated pack remains same, but the capacity increses,current handling and runtime increases too.

Connecting a pair of 1s, 3.7v,5000Mah LiPo's in Parallel:

This will increase the Mahx 2 but the voltage will remain the same for a result of 3.7v, 10000mAh.

Parallel is 3.7v,but you have to based on your RC models’/drones’ norminal power.The voltage is unchanged,but the current is big, after you’ve operated your RC models/drones for a long time,the excess current would shorten the lifespan of your 7.4v lipo battery.So it would do more harm.Please don’t parallel too many cells,keep the current under the norminal current,and you need to change the charger.

If you really want to play them for a longer time,and save you a lot of trouble,you can buy one new battery.The most important thing is that you don't have to change the charger because of the increasing capacity.

Either in serial or in parallel connection, the output power of the battery pack is increased. Parallel Connection is to increase using time,while Serial connection is to increase the speed.

RC lipo battery above discharge and also the good utilization of motive

Some rookies feel that lithium batteries brand improved,ever the greater the price,it is actually improved to work with the longer. But normally not the situation, even the best lithium batteries,over-discharge phenomenon will appear.

How to use the suitable of lithium battery?

Regardless of whether lipo battery 3.7v or 1.2v NiMH,won't suggest voltage once the battery is thoroughly charged.For 2200mah lipo battery, the common after total voltage reaches four.2v,I feel plenty of people have the mobile phone batteries universal charge,it output voltage is generally indicated above four.2v.NiMH full charge can attain 1.5v. Moreover to voltage,and after that there is certainly capability and discharge price.the capacity of your battery in mah,the discharge charge is an unit with C. In brief,1C for distinct capacity battery just isn't exactly the same. 1C discharge signifies that batteries can final for one hour. Illustration: 1500mah capacity battery lasted 1 hour of operate, the typical current is 1500ma, namely one.5A,one.5A and that that is if the battery 1C above the nominal greatest 10C the battery discharge latest is 15A... That is definitely under the battery 15A is harmless to use. Once more 1000mah capacity inside the 1C is 1000ma, namely 1A. When the over nominal 15C. Then the utmost discharge current is 1A * 15 = 15A, the utmost discharge recent of the battery is 15A. Having said that, the above get the job done the batteries 15A, 10C discharge is, in theory, the maximum recent operate employing 60/10 = six minutes . And 1000mah get the job done to 15A, 15C is discharged for the recent theory may be used to get the job done 60/15 = 4 minutes. So rather speaking, 1500mah, 10C battery to become used for a extended time factors. So invest in the battery by looking at the quantity of C just isn't acceptable. C compact variety of discharged battery may discharge a big quantity greater than C. Related with this particular capacity.

Remote manage model aircraft lithium battery termed the lithium polymer battery, typically referred to as lithium or lithium batteries. I've to 11.1V lithium battery remote manage model aircraft as an example to illustrate tips on how to correctly use lithium battery. Generally, 11.1V lithium battery of remote control model aircraft by 3 lithium batteries in series (3S1P), per piece batteries voltage is three.7V. The lithium model, cell phones, cameras, and so on. The nominal voltage is named marking voltage is obtained from your typical working voltage. The actual voltage monolithic lithium batteries is 2.75~4.2V, lithium within the topic of electrical power capacity of 4.2V to 2.75V discharge obtained. Remote handle model aircraft lithium batteries need to be made use of inside the voltage selection of two.75~4.2V. The remote management model aircraft lithium battery voltage is lower than 2.75V belongs excessive discharge, lithium expands, chemical liquids within crystallize, these crystals may pierce the internal framework with the layer caused by a short circuit, make the lithium voltage turns into zero. Remote control model aircraft lithium battery voltage is over 4.2V belong overcharging, inner chemical reactions also intense, lithium will blow expansion, if it continues to swell charge combustion. Whether or not it really is above discharge or overcharge can have remote manage model aircraft lithium batteries produce lots of injury.

1.the charge

1-1 Charging recent: the charging existing should not exceed the specs book stipulated highest charging recent (below usual circumstances is 0.five ~ 1.0C or much less), the use of larger than encouraged charging existing may well lead to the battery charge and discharge performance, mechanical effectiveness and protection performance difficulties and may bring about heat or leakage. At the moment marketed 5C model aircraft battery charging current, charging is just not advisable regular use 5C, so as to not affect battery lifestyle.


1-2 charging voltage: the charging voltage shall not exceed the restrict voltage (gens ace 2s lipo / single cell), four.25V charge voltage of every part of the highest limit. (Non-straight to enrich my understanding, this could result in overcharging the batteries, users use the battery because of an error produced by the consequences).


1-3 Charging temperature: The battery needs to be charged inside of product or service specs prescribed ambient temperature variety, otherwise the battery vulnerable to injury. Once they locate the battery surface temperature anomaly time (refer to your battery surface temperature exceeds 50°C), must straight away stop charging.


1-4 reverse charging: Connect the battery constructive and unfavorable, non-reverse charging. In case the constructive and unfavorable reversed, we'll not have the ability to charge the battery. Reverse charging the battery are going to be destroyed, and even cause fever, leak, fire.

2.discharge

2-1 Discharge current: discharge present may not exceed specifications specified greatest discharge latest, high-current discharge capability will cause the sharp decline inside the battery to overheat and cause swelling.

2-2 Discharge temperature: The battery has to be discharged inside of specs specified working temperature assortment. Once the battery surface temperature exceeds 70??C, to suspend use until finally the battery is cooled to room temperature thus far.

2-3 over-discharge: over-discharge can harm the battery cannot be so single battery discharge voltage is reduced than 3.6V.

3. Storage

The battery should be positioned in awesome storage environment, long-term storage battery (a lot more than 3 months), it is actually advisable at a temperature of 10-25°C and a minimal temperature non-corrosive fuel environments. In the long-term storage battery each 3 months to sustain the battery charge and discharge activity and make sure that every cell voltage 2s lipo battery 5000mah inside the range of 3.7~3.9V.

Ways to eradicate the battery memory impact

What's the battery memory result?

If the battery is nickel cadmium battery, long-term will not be complete charge and discharge,it easy to leave a mark within the battery, the battery capability, this phenomenon is called battery memory effect.That mean, it appears that battery memory consumer daily charge and discharge charge as well as mode, time is tough to modify this kind of mode, can no longer do significantly charging or discharging.Lithium-ion batteries, no such result.

The reason behind the battery memory result

Resulting from adverse really sintering form in the traditional system, cadmium coarser grains, if nickel cadmium battery recharge in advance of they may be totally discharge, cadmium grain effortlessly gathered into pieces and produce a 2s 7.4v lipo battery discharge kind secondary discharge platform.

Battery will retailer the discharge platform and it since the finish from the discharge within the subsequent cycle, despite the fact that the capability of the battery itself could be make the battery discharge to your decrease platform.During the procedure of following the discharge of battery will only do not forget that lower capability.Exactly the same in each use, any incomplete discharge will deepen this effect, make the capability with the battery is reduced.

The best way to do away with the battery memory result?

To remove the effect, there are two techniques, 1 will be to use tiny latest depth of discharge (including with 0.one C to 0 v) 1 is to use big latest charge and discharge (e.g., one C) several times.

In practice, the method of elimination of memory results have strict specs and an operating method. Improper operation will be counterproductive.

For nickel cadmium battery, the upkeep of usual is deep discharge on the standard basis: the common use to get a month (or thirty instances circulation) on the deep discharge (discharge to 1.0 V/each section, named the work out), popular use is usually to use photovoltaic cells or make use of the signifies which include shutdown can lower the formation of the memory effect, but this is not training, since the instrument (including cell phone) is not employed 1.0 V/only to flip it off everyday, has to be special gear or line to finish the do the job, but luckily a lot of nickel cadmium battery charger with this particular perform.

For no nickel cadmium 7.4v lipo battery to training for any extended time, as the cumulative memory impact, cannot reply in training capacity, you then will ought to deeper discharge (termed a recondition), this is often an incredibly small present to get a long time for every area to 0.4 V battery discharge of the procedure, want specialist equipment.

For nickel metal hydride batteries, exercise within the frequency of about as soon as each three months can properly alleviate the memory result. Since the cycle daily life of nimh battery is lower than that of nickel cadmium battery, with little recondition this strategy.

Suggestion one: each and every time there is no really need to charge the 14.8v lipo battery just before discharge, and it really is hazardous, for the reason that useless shorten the lifestyle with the battery.

Suggestion two: use a resistor connect would be the cathode with the battery discharge is just not desirable, cannot management recent, easy to 0 v, even result in series of battery cell polarity reversal

How to charge of NiMH rechargeable batteries right

With the rapid development of digital industry,NiMH batteries with the advantage of its benefits,environmental protection is more and more get the favor player and bulk purchases.use also from traditional small household appliances product: lamps,clocks,electric toothbrushes,etc and other widely used to our new products,such as digital camera,electric toys,RC and others.

As people is constantly increasing,the number of NiMH batteries using and maintenance of science is gradually taken seriously by people,As we all know,the brand the service life of NiMH batteries according to the official claimed that can charge up to 1000 times,actually this is an ideal value,often less than this life. But as long as reasonable use charger,more in-depth understanding of NiMH batteries,we will still be able to let her prolong life. Tattu(lipo battery 5000mah) warm prompt the following tips:

Under normal circumstances,the new NiMH batteries contain only a small amount of electricity,when you buy to recharged and then use.But if the battery factory relatively time is shorter,power is adequate,recommended use before recharging.

1.A new NiMH battery generally after 3-4 times of charging and use,in order to play to the best performance.

2.This is very important:although NiMH batteries memory effect is small,still recommend recharging after each use as far possible,and with a full-time,not a charge in a while and then filling in a minute. 

3.When the battery is charging, the charge should pay attention to the heat around the charge,Don’t put to much stuff around,keep the battery clean.This is to avoid the problem such as power loss,keep the contact point at the ends of the battery and battery cover interior clean. 

4.Long time no use it ,remember to remove the batteries from the battery compartment ,put in dry environment recommended in the card battery box,to avoid short circuit. 

5.The NiMH batteries not use in long time can deposit in a few months later, nature into a state of ”dormancy”?batteries,the battery life is reduced greatly. If the NiMH batteries(3s 2200mah lipo) have been placed for a long time ,it is recommended to use the slow charge for charging. 

Traveling with Lipo Batteries You Should Notice

There are several advantages of Lipo batteries but there are also a few risk involved during charging, flying and transporting. We have been traveling across the US and Europe with a a number of our Lipo batteries and we always take special pro caution when traveling. Especially when traveling in an airplane. Before you go on an airplane trip, check your airline's regulations when it comes to batteries, review if your country's equivalence to the FAA has any guidelines. And then make sure you follow a few easy steps to improve safety and decrease the probability that something bad could happen.

There used to be some rule of numerous grams of lituim I think it was 11 grams which if i recall was about 5s 4000 mah that put you over the FAA limit. The rule if i recall is not to be in the suitcases in the hold but to go with carry on hand luggage. However some airlines can specifically choose to have their internal own rules and ban any lipos. That's often targeted at laptops with extra batteries as sometimes those caught fire in the overhead lockers . Those are often the Lipo types 11.1v 2200mah lipo or the modern 6s 4000 mah.

I've brought several Gens Ace 3s lipo 5000 mah and 11000 mah as carry on many times. Here is what I do. Wrap the plug and balance terminal in electric tape. Put lipos in gallon ziplocs, usually 2 per bag. Put the ziplocs in my lipo safe bags and all this in a separate tote. At the checkpoint I take the ziplocs out and lay them flat in a tray with nothing on top. I try to make contact with an agent and say 'hi these are my batteries.' After I get through the scanner, Usually before my stuff, I think back and try to make eye contact with the agents at the TV, when they get that look, I smile and wave and acknowledge that the suspicious stuff is mine. I then tell them they are for my copters, oblige the extra scan and bomb residue sweep. Then go on my way. Has worked every time, even traveling to other countries.

Quantities

The amount permitted is based on watt-hours (Wh). Wh establishes the lithium content by multiplying voltage with the ampere-hours (Ah). For example, 14.40V x 5Ah battery = 72Wh.

The current IATA dangerous goods regulations and your rights as passenger to carry the LiPos with you in carry-on luggage but not in your checked luggage. There are 3 classes of LiPo batteries. Below 100Wh there are no quantity restrictions as to the amount of batteries you can carry. Between 100Wh and 160Wh you are confined to two battery packs total per passenger. Above 160Wh you are not permitted to carry the packs as carry-on.

Avoiding short circuit

As another safety precaution, though this could not be mandatory according to flight safety regulations is to avoid short circuiting the batteries thus increasing the chance of fire hazard. This is fairly simple, all you need to do is to place each battery into an individual plastic bag. This will come in handy when labeling also, see below. You may also shrink wrap the battery connectors with saran wrap. This process only takes a few seconds and reduces the possibility of electrical arcing and moisture dealing with the battery connectors.

LiPo Bags

Placing your batteries in LiPo safe bags is an absolute necessity, if you don’t have them, do not even attempt to carry them on board an aircraft. This is also for your safety. Obviously you don't need to have a separate LiPo safe bag for each battery as you have also placed them in separate plastic bags as suggested above. But depending on the number and size of your batteries, be sure to have a bag with enough space for them all, or use multiple bags. This one is a great option, but you can buy larger ones also:

We've spent a ton of time combing the internet to know the rules so hopefully this post can help you out when you fly.  Here goes:

1. Do not put LiPos in your checked baggage. Should bad things happen the crew wants to be able to fight a battery fire.

2. Put the LiPos in your carryon baggage. If you've still got the original packaging, use it.  If not, put each battery in a separate plastic bag. Tape over the connector and the balancing plug.

3. This isn't a rule, but I always take the batteries out at the TSA inspections and put them in a separate tub. There is not point in trying to hide them because they stick out like a sore thumb in the X-ray scan.

4. You can only carry 2 batteries greater than 100 Watt-hr (e.g. a 6S 5000 mAh) on the plane.

5. How many less than 100 Watt-hr?  Here the rules are a little ambiguous with verbiage like "a reasonable number." I've carried 6 on international flights successfully.

6. This isn't a rule, but it's always a good idea to put the batteries in storage mode (about 50% SOC) to be safe.

7. I wish there was a single site that stated these rules but I haven't found one. The links below are a collection of them.  I print out the relevant pages and have them with me in case of trouble. At several airports the inspectors were very thankful for this documentation and made copies of it for themselves.

8. Generally, getting through security in the US hasn't been too bad, although you should allow extra time because they almost always do the extra sniffing tests on them. Internationally is another story because finding an English speaker is often hard.  My most difficult time was in Ulaan Baatar, Mongolia but we eventually prevailed.

Comparison of NiCd, NiMH, and Li-Ion Batteries

Land mobile portables have traditionally used Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) batteries. Lithium-Ion (Li-Ion) batteries were recently introduced as an additional chemistry alternative. This article will help users make an informed decision when selecting among NiCd, NiMH, and Li- Ion (Lipo) batteries. All chemistries have advantages and disadvantages that must be weighed before choosing a battery pack chemistry.

Battery Characteristics

NiMH batteries provide the following advantages over NiCd:

• Higher capacity

• Limited memory effect

• Environmentally friendly

NiCd batteries provide the following advantages over NiMH:

• Longer cycle life

• Wider range of operating temperatures

• Lower price

Li-Ion batteries provide the following advantages over the Nickel chemistries:

• Light weight

• Environmentally friendly

• No memory effect

• Highest energy density of the three chemistries

Choosing a Battery Type

Table 1 shows key parameter comparisons of NiCd, NiMH, and Li-Ion batteries.Operating Parameters

1. Relative Capacity – Electrical capacity of the batteries when compared to a NiCd pack. M/A-COM determines the capacity of its battery packs by testing. Some third parties rate their packs by using individual cell specifications. Cell manufacturers rate cells based on a slow charge and discharge. In land mobile radio applications, batteries are charged and discharged much more aggressively and will not reach their rated capacity. Also, when cells are connected in series, as they are in all battery packs, it is impossible to extract the rated cell capacity from the pack.
2. Charge/Discharge Cycle Life – This represents the number of times a battery can be charged and discharged, which equates to the lifetime of the pack. Usage patterns can lengthen or shorten this number.
3. Memory Effect – The memory effect occurs when a battery pack is repeatedly recharged before it has been completely discharged. The result is that even after a full recharge, the battery will not allow its full capacity to be extracted. Memory can be minimized by conditioning. NiMH batteries are less susceptible to memory effect. Li-Ion is not susceptible to memory effect.
4. Conditioning – Conditioning entails fully discharging and then recharging a battery 3 or more times. This can be performed with a Cadex C7400 or iTech BC3506QP-5 battery conditioner available from M/A-COM. See the Cadex or iTech manuals for instructions on how to use the products.
5. Operating Temperature – This is the range of temperatures at which the battery can be reliably used due to characteristics of the chemical reactions involved. At lower temperatures, the battery is not able to convert its chemical energy into electrical energy. At higher temperatures, safety devices called positive temperature coefficient (PTC) resistors inside the battery prevent it from being used until the temperature falls. Batteries that are used in very cold or very hot conditions for extended periods of time can be permanently damaged.
6. Charging Temperature – This is the temperature range in which batteries can be charged due to limitations of the chemistry. All M/A-COM chargers limit charging outside of this range per cell manufacturer’s ratings. This often affects vehicular chargers because vehicle temperatures can vary to extremes.
7. Storage Temperature – If batteries are stored above or below their storage temperature range, permanent performance degradation can result. In short, batteries must not be stored in excessively hot or cold locations.
8. Storage Charge State and Duration – All cells degrade over time. Nickel packs should be stored in a fully discharged state. Li-Ion packs should be stored at 40% charge. Li-Ion packs should not be stored for extended periods of time (3 to 6 months from manufacture).
9. High-Temperature Susceptibility – Prolonged high-temperature discharge damages the organic materials for both NiCd and NiMH. High-temperature discharge can occur while a user is operating the radio in a high-temperature environment, or if the battery is stored in a high-temperature environment. Short exposure to high temperatures will not permanently damage the cells. Short-term performance will be degraded, but can be recovered through a couple of charge/discharge cycles at room temperature (typically 77°F or 25°C).
10. Self-Discharge – Self-discharge is the gradual loss of charge over time for an unused cell. It is directly proportional to ambient temperature. The higher the temperature, the faster the battery discharges. The lower the temperature, the slower the battery discharges.
11. Recycling – By U.S. law, NiCd batteries must be recycled. Currently, NiMH cells are recommended but are not required to be recycled. Li-Ion batteries are not required to be recycled.

Conclusion:

This article presents the advantages and disadvantages of NiCd, NiMH, and Li-Ion batteries for portable radios to help users make an informed choice when selecting batteries. NiCd batteries provide more recharging cycles, operate over a wider temperature range, and are lower priced than NiMH batteries. NiMH batteries have a higher relative capacity, limited induced memory effect, and are environmentally friendly. Li-Ion has a higher volumetric efficiency than the nickel-based batteries. Li-Ion batteries have no memory effect and are environmentally friendly. According to the lipo voltage, there are 3.7v lipo battery, 2s lipo battery, 3s lipo battery, ect.
