The 3S 20A 18650 Li-ion Lithium Battery BMS is a type of battery management system (BMS) that is used to monitor and protect a 3-cell (3S) lithium-ion battery pack. The BMS is typically used in applications where a high-current, high-capacity battery pack is required, such as in electric vehicles or portable power systems.
A lithium-ion battery is a type of rechargeable battery that uses lithium ions to store energy. It is widely used in portable electronic devices and other applications where a lightweight, high-energy-density battery is required. The 18650 battery is a type of cylindrical lithium-ion battery that is commonly used in electronic devices and other applications. It is named after its dimensions, which are 18mm in diameter and 65mm in length.
The 3S 20A 18650 Li-ion Lithium Battery BMS is designed to protect the battery pack by monitoring the individual cell voltages and ensuring that they remain within a safe range. It may also have features such as overcharge protection, overdischarge protection, short-circuit protection, and temperature protection to help extend the life of the battery pack and prevent damage.
Suitable range: For nominal voltage 3.6V 3.7V lithium battery(Including 18650,26650, lithium polymer batteries)Product Size: 64mmx20mmx3.4mmMaterial: MetalCharging voltage: 12.6VMaximum output current: 20AMaximum output power / charging power: 252W
Note:1. Strictly according to the diagram wiring: 0V/4.2V/8.4V/12.6V,Otherwise it will cause damage to the chip.2. After connection, it need to first charge activation, then will have the output.3. Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better. Please buyers know the professional knowledge of this module before buying
