Hardware Operation

Thread the cable of the lithium cell through the square hole on the UPS lithium battery extension board to the port of the battery. Get one side of the USB cable plugged in the USB external power supply port on the UPS lithium battery extension board and the other side to the power supply port of RPi.
Toggle the UPS switch to ON, and the UPS will supply power outside. Choose a USB port from the double-USB at random to supply power for the RPi series mainboard. Toggle the switch to OFF if you want to power off the device.
MicroUSB provides power supply ports for outside charging UPS. When there is a 4.9-5.2V external power supply, the internal lithium cell of UPS starts being charged, and at the same time the STATUS light blinks. When the cell is charged, STATUS light turns to be ever bright.
