Description
The 3A 18650 Lithium Battery Charger Module with Battery Box and 5V Type-C Input is an integrated charging module with a battery enclosure, designed to charge individual 18650 lithium-ion cells efficiently and safely. It provides efficient charging, safety features, and modern connectivity, making it ideal for custom portable power solutions and small electronics.
Combining an integrated battery box with a robust 3A fast-charging circuit, this module ensures quick and secure power replenishment. Built-in protection circuitry safeguards your cells against overcharging, over-discharging, and short-circuits, while dual-color LED indicators provide clear real-time status telemetry (Red for charging, Green when full).
Note: Product images are for reference only; actual appearance, labeling, or component colors may vary slightly based on manufacturing batches. Batteries are not included.
Key Features
- Modern 5V Type-C USB Input: Features a robust Type-C port compatible with standard 5V wall adapters, laptops, and portable power banks.
- High-Speed 3A Charging Current: Delivers up to 3A of charging current to replenish 18650 cells significantly faster than standard 1A or 2A chargers.
- Comprehensive Circuit Protection: Built-in safeguards protect against overcharging, deep over-discharging, and short-circuit faults.
- Automatic Full-Charge Cut-Off: Automatically terminates the charging cycle once the battery reaches full capacity to prevent degradation.
- Integrated Battery Box Enclosure: Includes a secure physical housing for easy insertion, retention, and removal of single 18650 cells.
- Dual LED Status Telemetry: Integrated LED indicators display Red during active charging and Green when the battery is fully charged.
