This 3S 11.1V 10A Protection Board is specifically designed for lithium-ion battery packs composed of three 18650 cells connected in series, delivering a nominal voltage of 11.1 volts. It offers reliable and efficient overcharge, over-discharge, overcurrent, and short-circuit protection to ensure the safety and longevity of lithium-ion battery packs.
Built with advanced battery management ICs, this protection board actively monitors each cell’s voltage and current flow, preventing battery damage by disconnecting the pack or limiting current when unsafe conditions arise. It is rated for a continuous current of up to 10A, making it suitable for medium-power applications such as portable electronics, electric bikes, DIY battery packs, and other rechargeable systems requiring dependable battery safety features.
The board integrates balancing capabilities to maintain cell voltage uniformity, thus prolonging battery life and improving overall pack performance. Protection thresholds are carefully calibrated for typical 18650 lithium-ion chemistry, ensuring optimal operational safety and preventing thermal runaway or cell degradation.
Compact and lightweight, the PCB is easy to install with solder pads or connector terminals, making it highly adaptable for custom battery pack assemblies. It operates efficiently across typical battery operating temperatures and is designed to meet industry safety standards.
