A simple, no-frills 12V portable setup built to sit in a truck bed: a 300Ah battery, a 30A charger, a 40A DC-DC charger for topping off from the vehicle’s alternator while driving, a fuse, and a disconnect switch.
The customer helped design and build the wood board enclosure it’s mounted on — a nice example of what a straightforward, portable power setup can look like when a customer wants to be hands-on with part of the build.
