Single Battery Conversion Help

[krasselt21]

wondering if it is possible to just run a single battery, I would like to eliminate the passenger side battery. what has to be done?

Pull the battery out and done. Just make sure you protect the battery ends if you decide to keep them in place. I ran my truck for a year or so on one battery and the truck did not care all I got was a check brake system message while cranking sometimes.

You could run a single Odyssey 1750 or something similar.

Only issue I've had is not starting when cold. Otherwise no issue.

How did you wire yours? did you run everything over to battery or just tie together on passenger side?

I have mine on the frame rail, but you basically can run terminal posts, which will get power from the battery as you'll run you cable to that. You can then daisy chain another post on the passenger side to power your starter and anything else you might have over there.

thanks. that's what I am going to end up doing. use the terminals. its on a dedicated 6.4 sled puller. only gets using in summer.
whats the biggerst battery I can get to fit in battery box? any idea?

I built all new cables. Pretty sure I only needed to run 3 or 4 new cables. Was super easy.

I couldn't tell ya what fits, maybe someone else can chime in. Or take measurements

So I found a super simple way that is very clean to do the battery ******. On amazon there is a 4 post bus bar that I mounted under the PCM with a couple self tappers. Post 1 is going to the starter, post 2 goes to the alternator, 3 goes to the main power wire in the harness on the passenger side that comes up to the battery and post 4 is the feed from the drivers side battery that I zip tied to the heater core line that comes around the back of the engine. Simple as that!!!
