    It depends on how the battles are wired.

    If the battles are wired in series (think train cars) it increases the voltage of The circuit. Which means if the electronics require the higher voltage this may not work well, if at all.

    If the batteries are wired in parallel then this is basically half a fuel tank.

      In this case, we can tell it’s likely parallel because the springs (negative terminals) are on the same side. When the batteries are in series they’re usually placed in the compartment facing alternating directions.

        I always assumed this was like a universal truth, but I’ve found a couple of cases recently where they wired it in series despite the batteries all pointing the same way, I was so confused…
