The switched is the power switch, you can turn it into ON/OFF to turn on/off Jetson Nano Developer Kit
WARNING LED are the indicators of batteries, they turn on if you reverse batteries.
Note 1: Please check the WARNING LED when you mounting batteries, make sure that you set all the batteries in the correct way. You cannot charge batteries if you reverse them.
Note 2: The board may not work when you mount the batteries for the first time, you need to charge batteries on board for a while to activate them.
Note 3: Please use the charger provided, the module may be destroyed by other unsuitable power adapters/chargers.

How to use

You can just attach the UPS HAT on the 40PIN GPIO of Raspberry Pi or connect the i2c interface and to Raspberry Pi by wires. VCC should be connected to 3.3V
Open a terminal and run the following commands:

sudo apt-get install p7zip
wget https://www.waveshare.com/w/upload/d/d9/UPS_HAT.7z
7zr x UPS_HAT.7z -r -o./UPS_HAT
cd UPS_HAT
python3 INA219.py

OLED will display the IP address, battery voltage, current and the percentage of battery quantity, as well as the CPU, GPU and memory information after starting the server.

Note: if the current value is negative, it means that the batteries are feeding the Raspberry Pi. If the current value is positive, it means that the batteries are charging.
