18650 based UPS Hat for Raspberry-Pi - 5V 2.5A

Firstly, it is a HAT so you can plug it directly on the Raspberry-Pi GPIO. Add two 18650 batteries, plug it onto the Pi and Voilà: your hat can load the batteries from external PSU and powier up the Raspberry-Pi. Once the batteries loaded, then disconnect the PSU and the HAT automagicaly switch over the batteries to power up the Raspberry-Pi.

This UPS fits a protection circuitery for  overload/over-dischage/over-current as well as short circuit and reverse polarity.
Next to the voltage regulator delivering 2.5A @ 5V (continuous supply), this HAT do also have load balancing circuitery.

It also feature a voltage monitoring as well as a current monitoriing (based on INA219) all available via I2C bus. Thanks to this, you can keep an eye on the 18650 Lipo Load/Unload status. Great to save working files before final power outage.

It is also possible to power-up external project thanks to the USB output fitted on the HAT.

The two warning LEDs on the board alert the user about the over-discharged batteries. Notice that LED are blinking when the battery is connected the wrong way.
