(The output will be turned off when the load current is continuously less than 50mA.
Support external buttons, connect the button to K point and output negative pole, short press to turn on the power display and turn on the 5V output, two consecutive short presses will turn off the power display and turn off the 5v output.
When the charging current drops to 100mA after reaching the final float voltage, the charging cycle will be automatically terminated.When the battery voltage drops below 4.1V, the charging cycle restarts.When the battery voltage is lower than 2.8V, the battery will be precharged with a current of 180mA.
The USB-A female socket welding position is provided on the back of the product, and the female socket can be manually installed.
Support charging and discharging.
This model is the second edition, which reduces the size under the same performance and is convenient for installation in small spaces.
Product features: Type-C input, high charging voltage accuracy.
e: Adjusting the charging voltage setting requires power-off operation; the USB-A female socket on the back of the module is a 5V output terminal and needs to be soldered by the user. We will provide a female socket with the product.
