Question for you boat electricians. I'm planning to run 4 Gauge wire from my 2 12 volt parallel batteries in the rear to the front of the boat for my Bow Mount Trolling motor and Fish Finder. What size/rating Bus Bars do I need to connect the 4 gauge wire to?

Nevermind, found another post that answered my question. Ended up going with a single post bus bar.
