Powering a electric winch
My 2015 F350 diesel comes with 2 batteries, not sure how they are connected, so to connect winch to only 1 or run cable to both? Max draw about 400A.What says the gurus. Frank.

Ford OEM used garbage grade cables so replacements are a good idea. Running negative ground 2/0 cables directly from negative battery post to winch motor itself is also a good idea because stuff bolted together is not guaranteed excellent like stuff welded together.
In the last 25 years I have made 20+ sets of DLO 2/0 cable with lead coated cast copper fittings for Ford diesels. Soldered terminals, and cable negatives from both batteries to engine cylinder head then from there to a SOLDERED cast lug on the frame rail with bolt and nut. This is a forever fix. I kept track of many for over a decade. DLO insulation does not rot like the original. I used Red heat shrink on the positive lugs. Group 65 batteries are notorious fume spewers.
With Ford's adopting the ND gear reduction starter back peddling to 1/0 cable is fine. A stackable single ½" diameter stud is fine for cable junctions. Use stainless steel nut lock and flat washer and keep the nut tight as hell. Gobbing silicone grease all over exposed terminals is an excellent idea. One again to make it clear I use pure lead coated cast copper lugs. Not tin coated. Pure lead. Crimped then soldered. Cables like this must be purchased in components then assembled yourself.
