I'd like to add a new power supply to a board that came with 2xAAA batteries wired on. The issue is that the two batteries were connected on opposite ends of the board. I'd like my replacement power source to be a single battery pack or other power source and split the voltage using a jst splitter.
Is this even feasible with a jst splitter?
How much voltage/amps should I be supplying so that it matches the two AAA batteries going individually into the board.
I tried to use two AAA batteries in series to power the board but it seemed to not be enough power (or just didn't produce anything noticeable).

I have successfully made the board turn on if I attach a pack of 4xAA batteries to the board but it starts to overheat, so that isn't the answer of course.
