2 identical batteries in parallel, but unequal discharge?
MY own personal rule is two batteries, 150% current of one battery. So with two batteries each capable of 100 amps, with 2 in parallel, you can pull 150 amps, so even if there is a 50 amp difference, the high battery is only at 100 amps, and the low one is providing the other 50 amps. Go to 4 batteries, and now you should be safe pushing 225%.
ELI5. Why do most devices requiring AA or AAA batteries need
So you can combine batteries in parallel to have access to a greater capacity, but more often they are used in series to have the same capacity but instead double the voltage. 1.5V is useful for some types of circuits, but depending on the type of device it needs to drive, it may be simpler to do with a 3V (2 cells), 4.5V (3 cells), or 6V (4 cells) circuit rather than upping the voltage
