BMS module 6S, Li-Ion, 15A, 25.2V

BMS module designed to be used with 6 lithium-ion batteries in series, providing protection against overcharge, overdischarge and short circuits, thus extending battery life and protecting against damage.

The board has the capacity to manage up to 6 lithium-ion battery cells with a nominal voltage of 24V and a nominal current of 15A.

It is compatible with any lithium-ion battery that has a charging voltage of 4.2V per cell.

Characteristics:

Protection against overcharging: the PCB board will stop charging when the voltage exceeds the value of 4.28V per cell (do not charge above 4.2V per cell). This voltage is a safety voltage to prevent major damage, which is the purpose of the BMS. strictly follow the recommendations for use specific to each cell.

Protection against excessive discharge: the PCB board will stop the discharge when the battery voltage drops below the value of 2.55V per cell (do not discharge below 3V per cell). This voltage is a safety one to prevent major damage, this is the purpose of the BMS . strictly follow the recommendations for use specific to each cell.

Protection against short circuits: the PCB board will stop the discharge when the current exceeds the maximum value of 30A.
