Battery relocation ideas

[rocknhorse76]

How have you guys mounted your batteries when you moved them to the rear? I’m looking at either behind the passenger seat or all the way in the back. I don’t need any tips on wiring, just mounting.

I have done an Oddessey, on its side, under the passenger seat. Central and low mounted. Remarkably accessible. Open the passenger door to jump start someone. Ground cable to the transmission case and the hot cable was really short as well.

I was never willing to give up the cargo area for a battery.

The problem with that is that I have Mazda Miata seats mounted to my cage so there’s not enough room under the passenger seat unless I cut out the floor. I think it’s going in the back.

This really doesn’t seem like a bad spot. My toolbox and stuff still fit fine.

I'm just curious,what's the purpose of moving it from under the hood,to make more room ?

I tubed the front end and no longer have a core support or inner fenders. Since there’s no mounting spot up front anymore, I figure I may as well make some room for tires and move some weight off the front end.

what's tubing the front end?

 

[rocknhorse76]

Front fenders, grille, radiator, attached to round tubing instead of sheet metal. Makes the front end more solid and creates more room for big tires and suspension travel.

Here's mine with no inner fenders.

I got ya now and this is mostly done for an off road rig?

Yes

 

[rockinrich]

Yes

right on,thank you and good luck!

 

[rocknhorse76]

Thank you

For those who have mounted their batteries in the rear, how did you route your cables?

So you do need some tips on wiring!
Sorry I couldn't resist. Good luck with your project.

I’ve been an electrician for 27 years, so I know how I’m planning on doing it. Just curious how others have done it.

I’ve never rear mounted a battery in a bronco, but have many times in others. I always run the cables through and abrasion and heat resistant wrap and run them on the top or inside top edge of the frame. I wrap the cables individually, vibration in a vehicle, especially an off-road vehicle is a killer on wiring if it chafes at all. Ground cable isn’t such a big deal but the positive can make a fire if it rubs and shirts out.

I run the ground cable all the way to the engine block and use that location to ground the winch. There’s too much loss for high amp loads to ground through the frame like the winch and starter. It will make you chase silly crap forever, for instance spun bushings in your transmission because for some reason that became the path of least resistance.

Thanks, that’s pretty much exactly what I am in the process of doing. Just making sure that the electrician in me wasn’t over-complicating things when it came to the actual routing hahaha. Loom or heat sleeve on the positive anywhere it’s subject to damage. Ground cable runs all the way from the battery to the block with a giant ground strap from there to the frame. Military-spec battery terminals with covers, bulkhead fittings to pass through the floor rather than grommets, and a covered junction block up by the radiator for the positive cables. All US-made fittings from Fastronix. Did bulkhead fittings with my onboard air hoses too since I hate leaks lol.
