Product Description
The Type-C BMS 2S 2A Boost Lithium Battery Charger Board is a high-performance, intelligent power management module designed for multi-cell lithium polymer or 18650 battery packs. Equipped with a modern USB Type-C interface, this synchronous boost module steps up input voltages from DC 3V–6V to deliver an output voltage of 8.4V, perfect for replenishing dual-cell (2S) battery configurations. Its advanced step-up topology ensures robust energy conversion efficiency, maintaining low operating temperatures during high-current charging cycles.
Designed around the flexible MRB045 layout, this board offers outstanding customization for advanced makers. The backside features pre-configured solder pads allowing multi-purpose scaling for 2S, 3S, or 4S battery configurations, alongside adjustable current thresholds matching 1A, 2A, or 4A demands. Complete with onboard LED pads for real-time status monitoring and reliable input protection, this micro-sized boost charger serves as an ideal choice for custom drone assemblies, power tool restorations, handheld wireless devices, and high-efficiency multi-cell DIY electronics.
