Now that I think about it, can the ADS1115s also read negative voltages? In fact, the current on the shunts will flow in one direction during discharge and in the opposite direction during charging. I hope so, otherwise it would be a problem...
Short answer is Yes ......

ADS1115 can read negative voltages on a differential input ... so it will correctly measure current flowing in either direction

Just make sure the shunt voltage stays within the PGA range of your ADC.

Datasheet page has already been quoted .... in case of detailed info.

Check this tutorial out, ADS1115 used for getting values from heart monitoring sensor with RPi4: https://www.theengineeringprojects.com/ ... -pi-4.html
