One thing it allows you do is have smaller gauge wire to run everything. This is why airplanes use 24 V battery system to reduce weight in the wiring. And "Power" of a battery really depends more on size/construction than the voltage of the battery. So I would not think that a 42 volt battery(assuming same size/construction) would not have any more power than the standard 12 volt car battery.
