The use and maintenance of the FPV battery

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 3s 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.


How to experience the fun of flying FPV for beginners

The FPV just like the F1 racing car in the drone, which uses the first person view to control. In the process of flight, through the specified arches, high-speed turns sideways, all-around flips to control the flight. Then, when beginners to play FPV, how to fly it and what to attention?

1. Flight Security

The FPV hitting obstacles is inevitable with a high-speed flight in the air. So most of FPV have a anti-fall. But we should to pay more attention to the flight safety, avoiding to hurts somebody.

2. Choose Open Place

For the FPV racing, it just like the F1 racing car, there is a corresponding runway. For beginners, the FPV is suitable for flying in an open environment. Indoor or small-scale place is dangerous. And don’ choose place that have many trees,people or other obstacles.
You can search for open site on the website to practice. When your skill have high level, you can set arch to practice operations, and also to plan the special flight routes to increase the difficulty..

3. FPV Battery

The battery is also the key to experience the fun of flying FPV. At present, most of FPV battery flight time is about 10 to 20 minutes. So in order to flight more long time you can prepare more FPV batteries or choose the best lipo battery brand .

For the battery, I recommend the Tattu FPV batteries, they have a strong burst, high capacity and long flight time. At present, a lot of FPV drone pilots are using their batteries,such as 1300mAh lipo,1050mah lipo and 1800mah lipo battery, and they made outstanding achievements. So, the Tattu battery is worth to recommend and trust.

4. FPV image transmission

For beginners, it is very necessary to have a FPV image transmission display device. It is very helpful to determine the flight path, especially the direction control. Visual flight is a kind of training method for masters. So, the video display device is necessary, and the best choice to have high definition VR glasses.

5. An assembly or a set

In the FPV drone, the aircraft wheel base is usually used to distinguish the FPV. In addition to the difference in size, the flexibility, speed control, battery capacity and other aspects are different. When the size of wheelbase is large, the load bearing can also be increased, and the battery ,the beginners, the balanced 250 series which has the stable GPS is more suitable, and it is easier to control, so as not to burst.

FPV is a very interesting type of aerial UAV. With goggle glasses, Have a fun of flying FPV.


Introductory tutorial of FPV Drone

You will have fun if you are a FPV tyro expecting to operate a FPV drone casually but you have no suitable measures. Now we are providing a detailed introductory tutorial for you, hoping it can help you improve from an inexperienced rookie to a skillful veteran.

1. If you have never seen quadcopter, you need to buy a mini one like a toy. Although it looks very inconspicuous, but it has a genuine advantage that a formal FPV can’t compare with.

Firstly, it is extremely difficult to operate a FPV. Operating a FPV excellently needs long-terms accumulated skills. It is inevitable to land unsafely. So we need a mini quadcopter with low price and high safety to practice.

Secondly, a broad flying space is needed to operate a FPV, but mini quadcopter has seldom requirement for flying, with which you can practice at home.

For the two reasons above, do not start directly with the machine if you have no contact with quadcopter, which is very expensive and dangerous.

You can plan to buy a FPV when you are familiar perfectly with mastering a mini quadcopter.

After all, what kind of model should be chosen as the first FPV?

There are two kinds of FPV in the market. One is RTF (ready to fly) UAV which means you can operate it as soon as you get it. Another one needs you to choose and buy body frame, motor, screw propeller and relative electronic component, then assembly and test them.

If you have strong manipulative ability, we strongly recommend second plan because the process of DIY for UAV is full of pleasure. Moreover, you will get many various skills in the process, which will help you a lot in the future.

3.Structure of FPV drone

You have to be aware of the structure of FPV drone no matter what kind of plan you choose. A FPV can be divided into several parts below.
The body frame: the frame of the plane.

Four motors: used to drive the propeller rotation

Four ESC (electronic speed controller): used to adjust electric current and supply power for motors.

Four screw propellers: rotating generates pulling to drive the plane to fly

Flight controller: the brain of FPV controlling various flying posture

FPV Lipo battery: supply power for the FPV

Transmitter and receiver: used to transmit your control command to the FPV.

The components above can let the FPV fly and do some easy flying exercise. But if you want to enjoy real FPV, you need to ask help from the components below.

The camera and image transmission: used to transmit first view images seen from the FPV

FPV glass or screen: used to output the image seen from the FPV and give you an experience you are operating the plane.

Antenna: used too enlarge the signal from image transmission.

Having equipped with all the components above, you will go into the world of FPV. If you want to share your flying video, a HD camera is needed.

4 .Flying

You can fly with your friend when you can master a FPV skillfully.

5.Cautions for safety

Firstly, do not flying in crowded place.

Secondly, ensure the UAV are free by adjusting image signal before flying

Thirdly, practice with mini quadcopter before flying FPV. Besides, you are suggested to try with FPV after you are familiar with mini quadcopter.

Fourthly, ensure the power is sufficient before your flying or prepare several spare batteries because over-long continuation of flying journey contents you more and avoids crash from air for lack of power. Tattu battery is suggested for its long-time continuation and strong explosive.

The Best FPV Battery:Tattu R-line 95C Battery

After two weeks our 1300mah Tattu R-Line 95C batteries have got 15 charge-discharge cycles and now we can talk about them in a more accurate way than when they were new brand.

Comparing with other two 1300mah batteries of different types we have, including a “graphene” one, the R-line battery is the best. The “graphene” one almost reaches the performance of the R-line but its greater weight (also its measurements) makes the R-line win.

In the last cycles we have made it suffering by discharging it until 3.0v per cell. It came down hot but not as much as other batteries and after a few seconds the battery cells recover the voltage (3.5- 3.6v)
The internal resistance when the batteries were new was 001/001/001/001 Mohm and now, after 15 cycles is 002/002/002/003 Mohm

In my opinion, they are the best 1300mah batteries we have used so far. They have a great discharge from the beginning until the end of the flight regardless of what you force them. I think that Gens ace has done a good job with these batteries, I am looking forward to try the 1500mah packs.

How to Extend the Battery Flight Time of Drone FPV

Most Quadcopters have a flight time ranging between 3minutes to 20minutes. However, other cheaper models have a flight time shorter than this. The most puzzling question that Drone FPV pilots face is how to extend the flight time of the FPV battery in use.

There are many factors that affect the flight time of the FPV drone; such as the weight of the drone, winds, flight recording, and flight style. The addition of weight, presence of wind and recording your flight using a camera are some of the conditions that drain your FPV battery flight time.

Tips To Increase Your FPV Battery Time:

1. Choose a big battery.

Most Drone FPV models are fitted with mid-size batteries which do not offer flight time longer than seven minutes on average. Acquiring a battery with a higher mAh will increase your flight time. However, do not use a huge battery since it makes the drone heavier leading to more energy consumption, this impacts negatively on the flight time.

2. Choose a conservative flight mode

Drone FPV models have a range of flight modes. These are dependent on the transmitter sensitivity. To increase the FPV battery flight time, you should choose the less aggressive flight mode, which is the lower sensitivity flight mode.

3. Ditch the camera if pos sible

Some cameras are detachable. If yours is, it is highly recommended that you remove it. The camera drains the battery since it is heavy and also the recording itself link directly to the battery thus shortening its flight time.

4. Experiment different propeller sizes

The size of the propeller fitted on the drone affects the battery flight time since it impacts on the power consumption. Before using different propellers, start by experimenting with the manufacturer’s recommended propeller then use different sizes while observing the flight time observed using different sizes.

5. Charge the FPV battery at the right time

Do you charge your battery moments before using it or days before flying? Charging your battery long before using it decreases both the lifetime of your battery and the flight time during flying. It is recommended that you charge your battery some minutes before using it.

6. Fly in the appropriate conditions

If you fly your drone FPV outdoors, then you should consider the right conditions to fly in. Avoid windy or rainy conditions. Flying in the wind increases the resistance that the drone faces when turning. Higher resistance translates to more power consumption thus draining your battery faster. Rainy conditions also damage the drone’s battery.

7. Remove prop guards

Prop guard is the frame that covers the propeller to protect it. The propeller has an advantage since it protects the propeller. However it has a disadvantage since it increases the weight of the drone thus increasing the power consumption and reducing the battery flight time. Removing them will make your Drone FPV lighter thus consume less power during flight.

8. Do not overcharge the battery

FPV batteries can be dangerous when overcharged. It can explode and cause fire. Alternatively, overcharging reduces the lifetime the battery.

9. Do not allow the battery to drain completely

It is highly recommended that you don’t drain the drone’s battery. Ensure you do not fly the drone when the battery is less than 20% percent. This reduces the battery’s lifetime.

10. Consider making your own model

If you are not impressed by the time that your Drone FPV model offers, you may consider making your own drone. How do you go about this? Don’t worry; there are numerous sources of information on the internet that can guide you in making your customized model.

Commonly Used FPV Equipment of Play with FPV Sports

Unless you invest in the right FPV equipment, your experience while taking part in FPV sports may not be the best. Call it video piloting or remote-person view (RPV), but one certain thing is first-person view (FPV) is fast becoming a popular terminology in gaming and sporting. By using special devices or gadgets, a user is able to have a pilot’s or driver’s view as if inside an unmanned aerial vehicle (UAV). This makes the game more realistic, exciting and challenging. For this kind of view, the following FPV equipment is necessary:

FPV equipment: Camera

The camera provides the views or images of where you are driving or flying through. There are two kinds of cameras: Dedicated FPV and gopro camera. The dedicated type is specifically designed for FPV sport and is usually cheaper and lighter than other types such as the gopro camera. The sense of motion is also better. The gopro camera is suitable for those who are after basic experience and desire to have video/ photo feeds.

FPV equipment:Transmitter

The transmitter is without-a-doubt one of the vital FPV equipments. It wirelessly sends the signals from the transmitter to the receiver. For instance from the ground to the airborne station. The standard transmitter normally transmits at a frequency of 5.8 GHz 25mw. Anything higher may require a special license depending on the region. High-end transmitters have a wide frequency range and are compatible with different types of receivers.

FPV equipment:FPV Battery

To power both the aerial and ground station, it’s vital to rely on a source or power/energy. This is delivered via a set or pack of batteries. They make the machine fly or run as well as transmitting and receiving the radio signal. Modern batteries are more advanced, more powerful and also last much longer. Made from LiPo (lithium-ion), the batteries capacity ranges from 1050mah battery to 5000mah. They are also lighter so as to make the UAV lighter, faster and easy to maneuver.

FPV equipment:Antenna

Though it may seem like a basic accessory, the antenna is a vital component in FPV sports. In order to send and receive the radio signals, an antenna or aerial is needed. A high quality type is very sensitive and receptive and ensures minimal drag or signal delay. It’s also less-susceptible to distortion or interference from other signals or radio waves. When choosing a product, it pays to focus on the distance of sensitivity, effective radius and diffraction ability.


FPV equipment:Receiver

This component receives the video/image signal from the transmitter. There are different types in the market and each comes with unique specifications. You can go for a separate receiver that is ideally suited for USB capture cards or LCD monitor. There is also a receiver that forms part of the goggles or monitors. In addition to being more compact, this type is also easier to use.

Other notable equipments include the cradle head, video goggles, carrier aircraft, image display memory, extended-range remote control, On Screen Display (OSD), and OSD Modules. When buying the equipment whether glass, screen/display, antennae or FPV battery, it’s vital to get original FPV equipment from a reputable source.

The Benefits of Playing Drone FPV

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.


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.

What is FPV and the development of FPV

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!
