UPS Plus V6 For Raspberry Pi

UPS Plus is a new generation of UPS power management modules. It is designed with a “battery protection” function. The UPS can be configured to turn off the power when it detects that the battery power is low, to prevent the battery from over-discharging. It supports OTA firmware upgrade and supports RTC onboard.

And there are two INA219 chips onboard to detect 18650 lithium batteries voltage and voltage output from UPS Plus to Raspberry Pi.

Note: You have to enable the I2C function by using the "raspi-config" tool. Navigate to "interface options" and select "I2C" and enable it to follow the instructions. It is very important to enable I2C function on Raspberry Pi. Otherwise, Raspberry Pi will not detect UPSPLUS module.

How to assemble:

Note: DO NOT use different types of batteries at the same time! Please make sure the batteries are inserted with the correct polarity. Otherwise, the device will be damaged. 
Note: 18650 lithium batteries are not included. Please get them separately.
