2S 2A USB Type-C 8.4V Lithium Battery Charging Module for 18650 Li-ion Battery Pack

The 2S 2A USB Type-C lithium battery charging module is designed for charging two 3.7V lithium-ion cells connected in series. It provides an 8.4V charging output, suitable for 2S 18650 lithium-ion and compatible lithium-polymer battery packs.

The module accepts power through its onboard USB Type-C input port, making it convenient for DIY rechargeable battery packs and portable electronics projects. The board includes B+ and B− battery terminals, along with input voltage and ground soldering points for easy circuit integration.

Onboard CR and OK LED indicators display the charging condition and full-charge status. Its compact size makes it suitable for battery-powered speakers, robotics, emergency lights, electronic projects, portable devices and custom rechargeable power systems.

This board is mainly a charging module. Use an appropriate 2S BMS protection board separately when overcharge, over-discharge, overcurrent and short-circuit protection are required.

Important: Connect only a 2S battery pack. Check battery polarity carefully before soldering. Both cells should have the same chemistry, capacity, voltage and condition.
