This module, based on the TP4056 charger IC and DW01 battery protection IC, offers 1A charge current and cuts off when finished. The protection IC safeguards against over-voltage, reverse polarity connection, and low voltage. Connect the Type C cable for power or 5V DC to the IN+ and IN- pads. Connect the cell to charge to the B+/B- pads. Remember to disconnect the load when charging.
Important notes:
- 1. Ampere meter can only be connected to a 5V input end of the module.
- 2. It is recommended that the charging current is 37% of the battery capacity.
- 3. The connection wire should not be too thick.
- 4. Ensure the connection points are good.
- 5. If the input voltage is too high, the current will be adjusted to avoid damage.
- 6. NO reverse polarity.
