Thanks for these additional informations! I ordered some items to try to reproduce a similar setup. If you provide 3D print models, I'll ask a friend to print them for me 
At first, I couldn't understand how to connect the battery and charger (the red wires are mixed). Could you confirm this :
- The charger is powered by the USB port of the RPI, and enabled/disable by the relay.
- The relay board is powered by the 5V from the pin header of the RPI.
- The battery is connected to Vin+ and Vin- of the INA219 board
I'm sure that people would be interested to contribute to the project if you publish it on github/gitlab/whatever !
