My build is a little unusual so I thought I’d share.
I wanted to provide enough current to run a Warn M8 winch, a 12v fridge, sometimes an air compressor, along with LED lighting and miscellaneous smaller items. The winch can draw over 400A at full load which rules out a single LiFePo4 as most BMS’s max out at 200A. I went with a Group 65 Odyssey battery in a Ballistic Fab mount under lid for the front-right Decked bin. I’ve mounted a Victron shunt for a BMV-712 battery monitor on top of the battery mount. There is a solar panel mounted between my beef bars feeding the fuse block through a Victron MPPT controller. When the engine is running the aux battery can charge from the alternator via a Victron Cyrix-230A battery combiner. I mounted most items on an aluminum panel on the cab end and put a small auxiliary panel toward the tailgate so I can plug in the fridge and other small things as needed. It all seems solid so far.
