4S 16.8V 2A 18650 Lithium Battery Charger Module (USB Type-C)

The 4S 16.8V 2A 18650 Lithium Battery Charger Module is a quick-charging, high-efficiency solution specifically designed for 4-cell (4S) lithium-ion battery packs arranged in series. By utilizing a modern USB Type-C input, this module provides enhanced compatibility with contemporary cables, making it an ideal choice for reliable and portable power applications.

Safe and Balanced Power Management

This charger is engineered to ensure the long-term health and safety of your battery cells. It features automatic charging and balancing, which equalizes the voltage across the series cells during the charging process to prevent imbalances over multiple cycles. Additionally, integrated overcharge protection safeguards the pack by ensuring cells do not exceed safe voltage limits.

User-Friendly Status Monitoring

To provide real-time feedback, the module includes clear LED indicators. A Red LED typically signals that charging is currently in progress, while a Green LED indicates that the charging process is complete. Its compact and portable design allows for easy integration into a wide variety of DIY electronics and custom battery pack projects.
