3S 10A 18650 BMS Lithium Battery Charger

The 3S 10A 18650 BMS Lithium Battery Charger Protection Module is a Battery Management System (BMS) designed to protect and manage three-cell series (3S) lithium-ion battery packs. It is commonly used with 18650 Li-ion batteries to provide safe charging, balanced cell protection, and controlled discharge for custom battery packs.

This module supports a 3S battery configuration with a nominal voltage of 11.1V and a fully charged voltage of 12.6V. It provides essential protection features including overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection, and cell balancing to improve battery safety and lifespan.

The compact design makes it suitable for DIY battery packs, robotics, portable power supplies, electric tools, solar energy storage systems, and other battery-powered electronics projects.
