LiPo Charger Boost Board 2S 4A

The CN3302 LiPo Charger 2S 4A Module – USB-C is a compact, high-efficiency charging solution designed for 2-cell (2S) lithium battery packs. Powered by the CN3302 IC from Shanghai Consonance Electronics, it supports charging currents up to 2.2A and can accept input voltages between 3V and 6V (recommended 3.7–5V). The onboard USB-C port allows for modern, convenient power input while maintaining excellent compatibility with USB power sources or even solar panels.

Featuring intelligent charging control, the module automatically handles constant-current and constant-voltage phases, automatic recharge, and input adaptability for limited power sources. Built-in safety protections include low-voltage lockout, short-circuit, overtemperature, and overvoltage safeguards. Dual LED indicators clearly display charging and completion status, making this an ideal choice for DIY lithium battery projects, RC systems, and portable electronics.
