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!

Due to the good characteristics, the lipo battery is widely applied in mobile phones, cameras, laptops, cordless telephone, remote control, electronic toys and other electronic devices.

Li battery, nickel-cadmium battery and NI-MH battery

The cathode material of Lithium-ion battery is graphite crystal, and the anode material is Lithium superoxide (LiO2). In the charging process, Li-ion moves from anode to cathode and embeds in the graphite layer. In the discharging process, Li-ion separates from the cathode of graphite crystal and moves to anode. Apparently, Lithium is always appeared as Li-ion rather than Lithium metal in both charging and discharging process. Consequently, this kind of battery is called Li-ion battery, Lipo battery in short.
The advantages of Lipo batteries are small volume, huge capacity, light weight, non-pollution, high voltage of single cell, low self-discharging rate, more cycle times, but its price is comparatively high. Nickel – cadmium battery is gradually being replaced because of the low capacity, serious self-discharging and the pollution to the environment. NI-MH battery (nickel-metal hydride battery) is cost-efficient and eco-friendly, but since its single cell voltage is only 1.2V, it has some restrictions in the application.

The lipo battery characteristics

1. higher weight-energy rate, volume-energy rate.

2. high voltage. The single cell voltage is 3.6V, which equals to 3 nickel-cadmium battery or NI-MH battery put in series.

3.Keep for long because of the low self-discharging rate. (This is the most obvious advantage)
4. no memory effect. Lipo battery does not have the so-called memory effect as Lithium-cadmium battery, so there is no need to discharge it before charging.

5. Long lifespan. In the common working condition, the cycle times of charging and discharging is more than 500.

6.charging quickly. 0.5 to 1 time of current can be applied to the charging process, and the charging time can be shortened to 1-2 hours.

7. can be used in parallel

8. It is the most advanced “green” battery of the world, because it does not threaten the environment and does not have the heavy metal element like cadmium, lead or mercury.

9. high cost. Compared with other kinds of batteries, the Lipo battery is more expensive.

The internal structure of Lipo battery.

Lipo battery is often divided into cylinder and rectangular.
The internal structure is spiral, which puts a very precise and highly permeable polyethylene film between cathode and anode as a partition. The anode consists of the Li-ion collector made in Lithium and CoO2 and the current collector made in aluminum film. The cathode consists of Li-ion collector made in Carbon sheet materials and current collector made in bronze film. The battery is filled with organic electrolyte solution. Besides, there are safety valve and PTC component protecting the battery in the abnormality or short out.
The voltage of single cell is 3.6V, which is not the infinite capacity. Therefore, it is common to put the single li battery in series or in parallel to meet any demands.

The charging and discharging requirements of Lipo battery

1. The charging of Li battery: according to the structural characteristics, the maximum charging voltage of li battery is 4.2V. Over charging is prohibited as the battery would be damaged if the Li-ion from anode is taken too much. The charging and discharging process are demanding, so we can use the professional constant current, constant voltage charger. When the battery’s voltage reaches 4.2V in the constant current charging mode, the battery would be charged in the constant voltage mode. And when the current lowers the 100 mA, it should be stop charging.
Charging current=0.1-1.5 times of the battery capacity. (e.g. The charging current could be 130-1950Ma for the 1300mAh battery.)
2.The discharging of Lipo battery: due to the internal structure, the li-ion cannot move to anode completely in the discharging process. A part of Li- ion should be kept in cathode to guarantee the Li-ion can embed in the channel freely, or the lifespan would be shortened. To ensure that there is some Li-ion in the graphite layer after discharging, the minimum ultimate discharging voltage should be restricted. In other words, Lipo battery cannot over discharge. The common ultimate discharging voltage is 3.0V/cell, cannot lower than 2.5V/cell. The time of discharging depends on the battery capacity and discharging current. Discharging time(hours)=battery capacity/discharging current. Discharging current of Lipo battery(mA) cannot exceed three times of battery capacity. (e.g.10000mAh 6S should charged in the current of 30A, or it will damage.)

There are protecting plates in the internal Lipo battery group, so just control the external charging and discharging current.

The protective circuit of Lipo battery

The protective circuit of two cells consists of the two field-effect tube and dedicated protective manifold block; overcharging control valve and over discharging control valve are in the circuit in series, which is supervised and controlled by the protective IC. When voltage reaches up to 4.2V, the overcharging protective tube stops and charging ends. To avoid mistakes, delayed capacitance is added to external circuit. In the discharging process, when the voltage becomes 2.55V, over discharging control valve stops charging the load. Over-current protection is that stops discharging the load when large current flows across the load, which aims at protecting battery and field-effect tube. Over-current test is to use the on resistance of field-effect tube as the test resistance and supervise the voltage drop, stopping charging when exceed the set value. There is delayed circuit in the circuit to differ the surge current and short-circuit current. That circuit has complete function, reliable performance. It is professional and the manifold block cannot be purchased easily, so the amateurs are hard to fabricate.
