Now FPV all use Lipo battery, and there are many pilots that they all used 3s/4s battery in the FPV racing competition.

The so-called 3s is composed of three layers lithium cells in series that shows each cell voltage is 3.7 volts, each lithium chip actual voltage is in the range of 2.75 to 4.2 volts. The capacitance marked on lithium is that the energy was getting when 4.2 volts discharge to 2.7 volts. The FPV lithium voltage must be kept at the range of 2.75 volts to 4.2 volts for use. If the battery voltage is lower than 2.75 volts, it is excessive discharge, lithium battery will expand and the chemical liquid will crystallize. The crystallization may pierce the internal structure that cause battery short circuit, even changes voltage charge into zero. The remote model airplane voltage is higher than 4.2 volts, it is overdischarge, the internal chemical reaction is too excessive and the lithium will expand, if voltage keeps charging, the RC lipo battery will expand and burn.

No matter overdischarge or overcharge, both can cause a lot of damages to remote control model airplane battery.

Because FPV battery almost use for violent flight, so must pay attention to the skills about the use and maintenance of FPV battery.

1.The charge voltage should not exceed specified limited voltage (each battery chip is 4.2 volts), 4.25 volts is the highest limitation of each charge voltage. Charge current should not be too large (like the TATTU brand charger of 1500mAh 2 cell lipo battery should be set at 1.5 amperes to 2.5 amperes to charge)

2.Connect battery positive and negative electrodes correctly. If the anode and cathode of battery swap the cell’s poles over will not accept a charge. Reverse charge will make battery damage, cause heating, explosion, leaking and burn.

3.Overdischarge will make battery damage. When the battery discharges, monomer battery voltage should not be less than 3.6 volts (When single cell is 3.8 volts, the plane should almost begin to descend.)

4.The battery should be kept at a cool environment. When store the battery for a long time (over 3 weeks), suggest to put in the environment that temperature keeps at 10 to 25 degree Celsius, low temperature and non-corrosive gas. Battery needs to charge and discharge once three months to keep battery activity, and ensure every chip voltage in the range of 3.7 to 3.9 volts.

5.A good battery should have a good charger. Don’t use no-name charger.

6.FPV must choose the brand batteries, don’t use no-brand-name batteries. Single cell voltage has big difference.

7.When fly in the hot weather, try to choose the moments that before sunrise or after sunset that the temperature is not that high. Pay attention to the heat dissipation of the battery and the electronic speed controller. If can hang the batteries and electronic speed controller outside of the plane, try to dissipate heat outside.

Drones are undoubtedly a ground-breaking invention of the modern times. They are being used for numerous applications in various fields. But the one application that is gaining huge popularity nowadays is FPV racing. FPV or First-Person-View is attracting hundreds of pilots with its unique and newfangled approach. This is simply a race where the pilot can see live footage through the camera integrated on their drone. A special goggle with the in-built screen is worn by FPV racers where the live footage is transmitted.
As the name suggests, First Person View gives the user a feeling that he is up in the air and flying his drone first-hand. This is one of the most appealing factors about this game for both the pilots and the spectators.
An amazing race course is designed with several obstacles to make the drone FPV racing even more exciting and thrilling. A group of FPV racers comes together with their drones and state-of-the-art goggles to combat directly. The game enables them to fly up to 70 mph in places that are abandoned and isolated. However, in order to keep flying at the highest speed, it is absolutely necessary to use a high-end FPV battery in the drone. Such as Tattu 1300mah battery

What are the benefits of playing drone FPV for the pilots?

The foremost benefit of playing drone FPV is the chance to get to fly. Most of the pilots are simply attracted to the game because it provides a great experience of flying drones. It also offers a podium where they can encourage their DIY skills of building their own equipment. They can buy simple parts of the drone separately according to their prerequisites. Using these gears, they can fabricate their own FPV drone and participate in the races. If you have the knowledge and skill to build such innovative machines and fix the upcoming errors, you can venture out further.

The game is not limited to flying your self-built machine but is also bringing financial benefits to the players. There are various races being arranged for the FPV racers where they can take part. There is a grand winning prize for the winner too. One such example is the first drone race ‘World Drone Prix’ held in Dubai where a 15-year-old boy won $250,000.

What are the benefits for the spectators of the race?

For benefitting the spectators of the FPV racing, there are still attempts being made. The organizers are making every possible effort to bring thousands of by-standers to the stadium. However, the actual race is not that exciting to watch as it would be to see the live footages from a drone camera. Thus, efforts are in progress to give the race a more reality TV like effect.

With the ever-growing popularity of drone racing, it will not be wrong to expect a bright future in this sport. There are talented people who are making these machines themselves and are eager to participate in the races as well. We will have to wait and see what other benefits are possibly relevant to these FPV races in near future.

FPV is an acronym for “First Person View” and usually refers to the recreational sport of flying RC aircraft, with tiny cameras on board that transmit live video down to the aircraft operator/pilot.

It has been gaining popularity since the last decade due to the decreasing costs of FPV technology, and the ease with which live videos can be streamed these days. You will find tons of videos on Youtube, of footage from FPV aircraft, some of the more advanced set ups also show information such as speed, altitude and direction. GoPro cameras mounted on the plane provide steady and high definition footage that is streamed live from the antennas on board, or it can be stored until the aircraft lands for editing and uploading.

Flying one of these aircraft from a first person view perspective is extremely entertaining and has become a hobby as well as a sport among some serious enthusiasts who even hold FPV aircraft races.

Any model RC aircraft can be modified for FPV usage, including propeller based aircraft such as fixed wing airplanes, or RC balloons. Quadcopters are also a great platform for mounting cameras due to their ability to maneuver through tight spaces and hover steadily on top any location.

The basic FPV setup consists of a RC aircraft or drone, with a video camera mounted on board. This video camera which is usually powered by FPV batteries is linked to a transmitter that sends the live feed from the camera down to a receiving antenna on the ground. The place where the receiving antenna and operator are located is known as the “ground station”. The live feed from the aircraft can be seen through a pair of video glasses or a monitor. There are more complex setups that involve a motion detecting setup on the operators head, and a camera that can pan and tilt. This allows for a more realistic first person experience and the operator will feel like a real pilot sitting in the cockpit of an airplane, because the camera moves in the direction that he turns his head thanks to the motion sensors in his helmet/glasses. Now, there are many readily available kits in the RC hobbyist market for people who want to convert their regular RC aircraft into FPV models. These kits consist of a transmitter antenna and receiver antenna, in which the receiver antenna may or may not be mounted on the display. A camera is also included, usually alongside a pair of FPV goggles or screen. Also required is a nice set of FPV batteries to power your aircraft and on board cameras.

A good FPV battery is one that can provide consistent high discharge for a time period of 30 minutes to one hour. One of the most amazing battery models out there for FPV flying is the Tattu 1300mah battery that is a 4-cell 14.8 volt battery with a 75C continuous discharge rating. It is a lithium polymer battery with a burst discharge capacity of 150C, and is extremely light at just 154g. The light weight and powerful discharge ensure longer flight duration and higher performance for your FPV aircraft.

Once you have your FPV kit along with the battery, all you have to do is mount the antennas and camera on your RC model aircraft, plug in the battery and you are good to go. Wear the goggles, have a friend nearby to keep track of the airplane with a powerful set of binoculars, and set out on your journey as a model aircraft pilot!

Lipo batteries often refer to the polymer lithium batteries. According to the electrolyte materials, Li-ion battery is divided into liquid lithium ion battery and polymer lithium battery or plastic lithium battery. Do you know what are the difference between li-ion and li-polymer battery? Let us review these common senses with Gens Ace.

The difference between li-ion and li-polymer battery

Compare with li-ion battery,lipolymer battery has the following characterizations:
1. It would not leak the electrolyte, since it uses the colloidal solid rather than the liquid electrolyte.

2. It can be made into thin battery. For example, a 3.6V 400mAh 15C battery can have the thickness of 0.5mm.

3. It can be designed into multiple shapes.

4. The battery can distort and be flexible. The macromolecule battery can distort up to 900 around.

5. It can be made into single high voltage: the battery with liquid electrolyte can only acquire the high voltage and macromolecule battery by putting several batteries in series.

6. Because the battery itself does not have liquid, it is possible to obtain high voltage by making multi-layer combination inside the single battery.

7. The capacity is twice as that of the Li-ion battery.

The lifespan of lipo battery

The factor influenced the lifespan is the charging cycle, and the times of charging will not directly influence the lifespan.
For example, the first day, we charge the battery after consumed half of the power, and the second day, we repeat that process. This is just one charging cycle rather than two. Therefore, a cycle may be finished by several times of charging. Every single charging cycle will reduce the power slightly. However, a superior battery can maintain 80% power after many charging cycles. That is why some lipo battery can use normally after two or three years. Certainly, it is also needed that we replace the lipo battery if the lifespan has ended.
The lifespan of lipo battery is commonly 300-500 charging cycle. We set the Q as the power provided by one-time fully discharging. Ignoring the reduction of every charging cycle, the lipo battery can power 300Q-500Q through its lifespan. Accordingly, if we charge the battery after consuming power, the battery could be charged for 600-1000 times. (if we charge the battery after consuming 1/3 power, the battery could be charged for 900-1500 times.) we cannot tell the exact number of charging times if we charge randomly. In a word, the total power 300Q-500Q is constant. Therefore, the lifespan is related to the total charging power rather than the charging times. Besides, the difference between the influence of deep charging and discharging and the influence of light charging and discharging to lipo’s lifespan is similar.
In fact, light charging and light discharging benefit more to the lipo battery. Only when the lipo battery is calibrated by the product has the need to charge and discharge battery deeply. Therefore, we can use the lipo battery for convenience and do not have to concern about the lifespan.
If the 11.1v lipo battery is used above the regulated temperature (over 35 degree centigrade), the power will continuously decrease, which means the flight time would not be so long. If charged under the high temperature, the battery would be further damaged. It is unavoidable that storing under the high temperature will hurt the battery’s quality.
If using below the 4 degree centigrade, you would also find the flight time of the battery has been reduced, and even some original lipo batteries of mobile phones cannot be charged. But, this situation is just temporary. Differ from using in the high temperature, once the temperature gets higher and the molecules inside the battery are heated, the battery would recover to the normal energy.
To maximize the performance of lipo battery, we should use it more often and make the electron flow. If we cannot use the lipo battery frequently, please remember to make a charging cycle and calibrate it (charge and discharge deeply) every month.
