Features:
1. The output will be turned off when the load current is continuously less than 50mA.
2. Support external buttons, connect the button to point K and the negative output, short press to turn on the power display and turn on the 5V output, two short presses in a row will turn off the power display and turn off the 5V output.
3. When the charging current drops to 100mA after reaching the final float voltage, the drop automatically terminates the charging cycle.
4. When the battery voltage drops below 4.1V, the charging cycle restarts.
5. When the battery voltage is lower than 2.8V, the battery will be precharged with a current of 180mA.
6. The USB-A female socket welding position is provided on the back of the product, and the female socket can be manually installed.
Note: Adjusting the charging voltage setting requires power-off operation; the USB-A female socket on the back of the module needs to be welded by the user.We will provide a female socket with the product.
7. Support charging while preventing electricity.
