This BMS charge-discharge controller module comes with pre-soldered nickel strip ready to use for a single 18650 rechargeable cell. It has protection against short circuit, overcharge, and over-discharge. The charge controller turns off the power supply for the batteries when the maximum capacity of at least one battery is reached. Designed for over 30,000 hours of operation with a maximum allowable current of 5A. The module activates protection mode if the supply voltage exceeds the permissible value. To restore the module, re-apply voltage to the input of the BMS board or wait for the charge controller to automatically disable protection.
