BW BMS 3S 20A with active balancer

Balancing BMS for 3S lithium battery cells. Used to protect the battery against over-discharge or over-charge. Using the battery without a BMS will result in damage to the battery.

The BMS monitors the voltage of all cells and ensures that they are evenly charged. If the BMS detects that any of the set limits are exceeded, it protects the battery from damage by cutting off the power supply.
