Description
The 4S 16.8V 1A 18650 Lithium Battery Charger Module with Type-C Port is a specialized charging solution engineered for 4-series (4S) 16.8V lithium-ion battery packs built from 18650 cells. Combining a modern USB Type-C input with automated charging, balancing, and protection circuitry, this compact module ensures your multi-cell packs remain safe, balanced, and fully energized.
Equipped with built-in overcharge protection and automatic cell balancing, it prevents voltage discrepancies across cells over multiple charge cycles. Integrated dual-color LED indicators provide clear real-time status telemetry (Red for active charging, Green when fully charged).
Note: Product images are for reference only; actual appearance, labeling, or component colors may vary slightly based on manufacturing batches. 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.
- Automatic Charging & Cell Balancing: Actively charges and balances series cells to prevent degradation caused by cell voltage imbalances.
- Overcharge Protection: Built-in safety circuitry stops charging when safe voltage thresholds are reached to protect the battery pack.
- Dual LED Status Telemetry: Integrated LED indicators display Red during active charging and Green when the charging cycle is complete.
- Compact & Lightweight: Measures just 25 × 18 × 6 mm and weighs a mere 6 grams for easy integration into DIY enclosures.
Benefits
- Extended Pack Lifespan: Integrated balancing and precise voltage cutoff protect multi-cell lithium packs from thermal stress and premature wear.
- Convenient USB Power Source: Allows you to recharge 16.8V battery assemblies using accessible 5V USB power adapters or portable power banks.
- Streamlined Prototyping: Compact PCB layout easily integrates into custom portable electronics and battery-powered gear.
Applications
- DIY Portable Power Packs: Custom 4S 16.8V battery chargers and power sources for field equipment and maker builds.
- LED Lighting & Instruments: Charging module for portable 16.8V LED work lights, test instruments, and custom electronics.
- Robotics & Hobby Electronics: Reliable benchtop or embedded charging module for small robotic battery packs.
