Type-C 2S Lithium Battery Charging Boost Module

This Type-C 2S Lithium Battery Charging Boost Module is a compact and efficient solution designed specifically for charging 7.4V (2S) lithium battery packs. It supports modern USB Type-C input with QC fast charging, automatically adjusting the input voltage to improve charging efficiency. The module features a built-in boost converter, allowing it to operate even when the input voltage is lower than the battery voltage. It also includes a battery balancing function via the BM pin, helping maintain equal voltage between the two cells for safer and more stable operation. With adjustable charging current, high efficiency up to 94%, and flexible input options (Type-C or solder pads), this module is ideal for DIY electronics, battery packs, and portable power applications. Features: Designed for 2S (7.4V) lithium battery packs Type-C QC fast charging support Built-in boost converter for low-voltage input Battery balancing function via BM pin Adjustable charging current using resistor High efficiency up to 94% Dual input: Type-C port or solder pads Compact and easy for DIY integration Package Includes: 1 x Type-C 2S Lithium Battery Charging Boost Module
