Description

The 4S 16.8V Type-C Lithium Battery Charging Board (2A) is a compact and efficient charging solution designed for 4-cell lithium-ion or lithium-polymer battery packs. Featuring a Type-C input interface, it supports up to 2A input current with an output charging voltage of 16.8V and 0.56A charging current. Built-in protection mechanisms safeguard against overvoltage, low-input, and short-circuit conditions, ensuring stable and safe charging performance. The high switching frequency of up to 1MHz provides superior efficiency, while the quasi-constant voltage mode compensates for voltage losses caused by internal resistance. With LED indicators displaying charge and full status, and automatic regulation to maintain battery health, this module is perfect for DIY projects, portable electronics, and embedded systems that rely on 4-cell lithium power configurations.
