- Li-Po: They offer more charging cycles just like Li-ion batteries, with the difference that they are lighter and have less chance of leaking, but they have lower capacity.
- Li-ion: They offer more charging cycles compared to older ones based on nickel or lead. They do not discharge easily when stored and we can charge them whenever we want.
- Ni-MH: They offer great capacity and are made with more environmentally friendly materials compared to Ni-Cd. They should only be recharged when fully discharged, otherwise they lose their performance.
- The individual cells that are connected in series to provide the desired voltage (Volt). For example, a "3S" battery contains 3 lithium cells connected together. More cells mean higher voltage and usually greater power.
- The discharge rate, also known as C-Rating, usually refers to Li-Po batteries and indicates how quickly the battery can safely deliver its current without overheating or swelling.
- Low Discharge (1C - 25C): Low-discharge batteries suitable for transmitters/receivers, FPV, and basic remote-controlled models & drones.
- Medium Discharge (30C - 50C): Medium consumption batteries suitable for basic remote-controlled airplanes, vehicles & drones.
- High Discharge (60C - 95C): High-performance batteries suitable for fast remote-controlled models & 3D flight.
- Extreme Discharge (100C+): Batteries exclusively for FPV Racing/Freestyle Drones and Drag RC cars that draw huge amounts of current in seconds.
- Wh is calculated using the formula: (Voltage x Capacity) / 1000. Batteries <100Wh, the IATA limit, are safe for carry-on luggage. Between 100Wh and 160Wh, airline approval is required, while batteries over 160Wh are not safe for flight.
