Working Principle of LiFePO4 4S 100A BMS

This BMS continuously monitors the voltage of each cell in your 4-cell battery pack.

• If any cell exceeds 3.65V, the BMS cuts off charging to prevent overcharging.

• When a cell drops below 2.0V, it stops discharging to protect the battery.

• The balancing circuit activates during charging to equalize voltages, ensuring each cell remains within a safe range.

By regulating charge and discharge cycles, the BMS guarantees stable performance, efficient energy transfer, and extended battery life.
