3S 10A Lithium BMS Battery Protection Board for 11.1V / 12V / 12.6V Battery Packs

The 3S 10A Lithium BMS is a compact and reliable battery protection board designed for 3-series (3S) lithium-ion battery packs with nominal voltages of 11.1V and a maximum charge voltage of 12.6V. This board ensures safe battery operation by managing charging, discharging, and current flow while protecting each cell from electrical damage.

This lithium battery protection board supports a continuous discharge current of up to 10A, making it suitable for low-to-medium power applications such as DIY battery packs, backup power units, portable electronics, robotics projects, and small solar energy systems. The BMS continuously monitors battery conditions and automatically disconnects the circuit in unsafe situations.

Designed for easy integration, the board works perfectly with 18650 lithium-ion cells and other compatible lithium batteries. Its lightweight PCB construction allows it to fit neatly inside custom battery enclosures without adding bulk.

Key Features of 3S 10A Lithium BMS

• Designed for 3S lithium-ion battery configurations
