At 48v you can use much smaller gauge wire than at 12v. Which means lower cost, less weight and a smaller footprint for your wire harnesses. One of the things that can “get you” with these higher voltage systems is you can’t use them to jumpstart the present majority of cars. While I’ve yet to actually see a higher voltage car, I would hope they’d put warnings by the battery to remind the user that “hey, don’t try to jumpstart your friends car with this battery!”
