    It’s really no difference from what you have now. The jumpers basically make it one big battery.
    If yours has all black cables, I recommend you mark all the positive cables in some way.

    I do coloured zip ties through the eye of the terminals. Everything that came off a post gets tied together.

    Looks easy enough now, I have a set of small cables made to add the 4th batt but I don’t like how it fit. I am going to order a set of factory made ones (not Pete brand as I value my money lol)

    I don’t really like the one in the pic. If you have a problem with the single jumpers it’s easier to inspect and if one is bad just toss it instead of the whole harness.

    I built my own cables when I put a 12 valve in my Chevy. I just went to Napa and bought some 2/0 cable, and used Fusion terminals like these:
    Fusion Solder Lugs and Terminal Connectors

    Came out nice, and it was easy to do. The terminals are already filled with solder. Just put it in a vice, heat it up, and push the cable in. Done. Add some thick red or black shrink tube as you see fit.

    Those would work pretty nice.
