Description
The 4S 16.8V 2A 18650 Lithium Battery Charger Module with Type-C Port is a high-efficiency charger designed for 4-cell (4S) lithium-ion battery packs arranged in series, commonly using 18650 cells. This charger module is an efficient, quick-charging solution for 4S 18650 lithium-ion battery packs, making it an ideal choice for various applications that need reliable, portable power.
Equipped with built-in overcharge protection, automatic cell balancing, and a modern Type-C USB interface, it ensures your multi-cell packs remain safe, balanced, and fully energized. Dual-color LED indicators provide clear real-time status telemetry (Red for active charging, Green when fully charged).
Note: Actual product may vary in terms of design. Battery packs are not included.
Key Features
- Modern USB Type-C Input: Features a robust Type-C port compatible with standard modern USB cables, power banks, and 5V wall adapters.
- 4S 16.8V Series Architecture: Specifically designed to safely charge 4-cell in-series 18650 lithium-ion battery packs up to 16.8V output.
- High-Speed 2A Charging Current: Delivers up to 2A of charging current to replenish multi-cell 18650 packs faster than standard 1A modules.
- Automatic Charging & Cell Balancing: Actively charges series cells while balancing them to prevent performance degradation caused by cell voltage discrepancies.
- Overcharge Protection Circuitry: Protects the battery pack from overcharging by ensuring individual cells do not exceed safe voltage thresholds.
- Dual LED Status Telemetry: Integrated LED indicators display Red during active charging and Green when the charging cycle is complete.
- Compact & Lightweight Footprint: Measures just 25 × 18 × 6 mm and weighs a mere 6 grams for easy integration into custom enclosures and battery packs.
