1S 3.7V 3A 2MOS BMS Li-ion 18650 Battery Protection Board

BMS (Battery Management System) – a battery management system that is designed to monitor the status of batteries, control the process of charging/discharging the battery, etc.

This BMS module has protection against short circuits, overcharges and over-discharge. One of the functions of the charge controller is to turn off the power supply for the batteries when the maximum capacity of at least one battery is reached. This BMS controller is designed for more than 30,000 hours of operation. The maximum allowable current is 3A.

If the maximum permissible value of the supply voltage is exceeded, the charge controller activates the “protection” mode. In order to restore the module, it is necessary to re-apply voltage to the input of the BMS board or wait a while until the charge controller automatically disables protection.
