Lithium Battery Charger Protection Module (BMS) 3S 40A 12.6V

3S 40A Battery Management System (BMS)

The 3S 40A Battery Management System (BMS) is an essential component for safely managing 3-series lithium-ion battery packs with a full charge voltage of 12.6V. This module provides critical protection features, including overcharge, over-discharge, overcurrent, and short circuit protection, ensuring the safety and longevity of your battery pack.

Select models also offer balance charging, which equalizes the voltage across individual cells to optimize performance and extend battery life. Compact and efficient, this BMS is ideal for high-current applications such as electric drills, agricultural sprayers, LED lighting systems, and low-power inverters (up to 400W). It’s a versatile choice for DIY enthusiasts and professionals building custom battery solutions.
