Ultimate Protection for Your Lithium-Ion Projects

Working with 18650 lithium batteries requires precision and absolute safety. Whether you are repairing a flashlight, building a custom power bank, or designing reliable power systems for STEM electronics like Arduino and Raspberry Pi, battery health is critical. This 1S (Single Cell) Battery Management System (BMS) acts as a vigilant safeguard for your power source, ensuring every charge and discharge cycle is perfectly regulated.

Why You Need a Dedicated BMS Module

Lithium-ion cells possess incredible energy density but are highly sensitive to voltage extremes. Our protection board actively monitors your 3.7V cell. If the voltage spikes dangerously high during charging or drops too low under heavy load, the board instantly severs the connection. This critical intervention prevents irreversible cell chemistry damage, swelling, overheating, and potential fire hazards, giving your hardware enterprise-grade stability.

Ultra-Compact Design, Robust 10A Output

Despite its ultra-compact 35mm footprint, this PCB efficiently handles a continuous working current of up to 10A, with momentary peaks up to 12A. This makes it perfect for high-drain applications like DC motors, custom LED lighting rigs, and portable power tools. You never have to compromise on performance to guarantee the safety of your electronics.
