2S 2A Type-C To 8.4V Step-Up Boost LiPo Polymer Li-Ion Charger

The 2S 8.4V Type-C Lithium Battery Charging Board (2A) is a highly efficient and compact charging module designed for 2-cell lithium-ion or lithium-polymer battery packs. Supporting Type-C input, it ensures reliable power delivery and stable performance with a charging voltage of 8.4V and a current of 1.1A. Equipped with smart features such as battery overvoltage, short-circuit, and low-input protection, this module ensures safe and efficient battery management. The onboard LED indicators display charging and full-charge status in real-time, while its quasi-constant voltage mode helps compensate for voltage losses due to internal resistance.

Features:

1. Type-C Input Interface: Enables universal compatibility and convenient charging via modern USB ports.
2. High Efficiency: Operates with up to 1MHz switching frequency for optimized energy conversion.
3. Comprehensive Protection: Includes overvoltage, low-input, and short-circuit safeguards.
4. Voltage Compensation: Maintains stable charging by adjusting for battery internal resistance losses.
5. LED Status Indicators: Displays real-time charging and full-charge conditions.
6. Automatic Recharge Function: Simplifies battery maintenance and prolongs lifespan.
7. Compact Design: Ideal for integration into small electronic devices or DIY projects.
