Usage method


When the Micro USB interface is powered on, the LED2 red light stays on, indicating that power is connected. When B+B - is connected to the battery, the LED2 red light flashes, indicating that charging is in progress. After charging to full capacity, the LED2 red light turns on normally. When discharging the battery and outputting USB, if the MicroUsB interface is not connected, and the B+B interface is connected to the battery and the output USB interface is not connected to the load, the IED2 red light does not light up. When the load is connected, the LED2 red light stays on for a period of time and then flashes. When the battery voltage is below about 3.2V, the USB cannot output normally. When the MicroUsB interface is connected to a 5V/2A charger for power supply, it charges and discharges at the same time, and LED2 displays the battery charging status.
