Hello,
I build a system based on arduino, the thing is powered by two 9v batteries in parallel, for longer operation and battery hot swap
I wanted to know if it was possible to measure individual battery voltage (to display on an lcd) ?
since both + poles are connected together I can only measure both batteries
would adding a diode do the trick ?
here is a quick sketch I made
Thanks
