PRODUCT DESCRIPTION
The 5S 15A 18650 Lithium Battery Protection Board monitors the status of batteries and controls the charging/discharging process.
This module can connect five batteries (18650) at the same time and protect them from short circuit, overcharge and over-discharge. It can also cut off the power supply when any battery reaches its maximum capacity. The BMS controller has a lifespan of more than 30,000 hours and a maximum current of 25 A.
If the supply voltage exceeds the maximum limit, the module will enter the “protection” mode. To reset the module, either apply voltage to the BMS board input again or wait for some time until the module automatically turns off the protection.
Features:
- Small size designed for a four-cell battery pack.
- Simple and convenient circuit for easy connections
- Over-charge/Over-discharge Protection.
