I need to measure the individual battery voltage in a pack. now, I can see that I need n+1 leads (for n batteries), but is there a way to set a microcontroller to take the difference between each analog I/O? Or would this really be a MCU specific question? The potential across any given battery cell should never go above the usual 5V range, so I don't think I would need to worry about blowing the controller if it's doable.
Thanks!!
