PRODUCT DESCRIPTION
The 5S 15A 18650 Lithium Battery Protection Board is designed to monitor battery status and manage the charge/discharge process.
This unit can simultaneously connect five 18650 batteries, safeguarding them against short circuits, overcharging, and over-discharging. It also disconnects the power when a battery reaches full capacity. The BMS controller boasts a lifespan exceeding 30,000 hours and can handle a maximum current of 25A.
Should the supply voltage surpass the upper threshold, the module will switch to “protection” mode. To reset the module, one can reapply voltage to the BMS board input or wait until the module automatically deactivates the protection.
Features:
- Small size designed for a four-cell battery pack.
- Simple and convenient circuit for easy connections
- Over-charge/Over-discharge Protection.
