The 18650 12V 10A Lithium Battery Protection Board is a reliable Battery Management System (BMS) designed for 3-cell (3S) lithium-ion battery packs. Compatible with 11.1V nominal and 12.6V fully charged battery configurations, this protection board ensures safe and efficient battery operation through advanced protection mechanisms.
Engineered for high reliability and low power consumption, the board protects lithium battery packs from overcharging, over-discharging, overcurrent conditions, and short circuits. Its compact size makes it ideal for applications where space, integration, and cost efficiency are critical.
The board features automatic recovery functionality, restoring normal operation once fault conditions are removed. With an ultra-low quiescent current of less than 30μA and an operational lifespan exceeding 30,000 hours, it provides long-lasting performance while minimizing battery drain during standby.
