## Description

Designed for 6S Li-Ion packs up to 25.2V, this BMS ensures safe battery management and extends battery life. It offers overcharge, overdischarge and short circuit protection, supports 15A nominal current with a peak of up to 25A, is compatible with 4.2V cells when charging and has low idle power consumption.
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.
