If you are looking into DC to DC converters, a reasonable starting point
is people that sell solar power equipment, or marine electrical
equipment. That all runs at different DC voltages, and typically use
racks of car batteries for storage.

There is no silver bullet. Plus, werewolves make better neighbors
