This module uses the TP4056 charger IC and DW01 battery protection IC. It provides 1A charge current and cuts off when charging is complete. The protection IC safeguards against low voltage, over-voltage, and reverse polarity connections.
To use the module, connect a micro USB cable or 5V DC to the IN+ and IN- pads. Connect the cell to B+/B- pads for charging. Remember to disconnect any load during charging. The red LED indicates charging, and green LED signals a full charge.
Important notes:
- Connect the ampere meter to a 5V input.
- Maintain charging current at 37% of the battery capacity for optimal performance.
- Use appropriate connection wires.
- Ensure correct connection points.
- Normal current reduction for high input voltage.
- Avoid reverse polarity.
Package Includes:
- 1 x TP4056 1A Li-Ion Battery Charging Module Micro USB with Current Protection
