I thought about getting rid of the 12v battery. But for now until I really know what goes on with my daily driving conditions I am better off leaving it. It could be useful to get a 72V to 14V converter and do away with the alternator and normal battery. The car will still see normal voltage and not have the alt load.
But I don't know what kind of converter I would need that could handle the headlights, wipers, and defroster all at the same time as well as powering the computer and fuel pump.
I am probably going to go with a garden tractor battery to save space for my main battery. If it goes dead I could always jump start myself without a lot of trouble
