Battery Relocation

[Studdley]

Thinking about doing a battery relocate to clean up the engine bay a little bit and for a little bit better weight distribution. What parts would you all use to going about doing so or would you opt for a kit. Also, where would you all route the wires through the cabin?

I got battery moved to trunk, my +/- cables are routed under passanger´s side door (don't know what that space is called) and through the firewall to engine compartment.

Going through all that for a 40 pound weight reduction?

Well I got fiber glass front bumber as well

Do you have any pics of your set up?

It isn't solely about weight reduction, it is more about weight distribution and to a lesser degree, getting the battery away from engine heat

You need a battery box that is vented and the vent needs to exit the car- that is a hose run from the box and out through the trunk pan or drop off. If you will ever run it on a race course you need a battery cut off switch at the rear. Batteries will last longer if mounted with the wide side running across the car, but it is a relatively minor difference. If you don't have a roll cage, you can bolt right through the rear rail with 3/8ths threaded rod. A fuse in line is really the best way to wire it and if you wire it wrong it can damage your alternator when you switch off a disconnect. I did it a few years ago-there was a post floating around. Added a roll bar, so it is being relocated to yet a third location

I have a spare taylors aluminum battery box if you need one, I'll sell it at a fair price (just don't ask who it is fair to!)

Luckily I already have a rust hole in my trunk so that I can run the vent tube there

So convenient!

Seems that I only got pic where I routed it. Plus cable already in place. Minus cable fits also there. I used 6 AWG eletrical stranded copper cable.

I dunno, but #6 seems kinda light, google "moving battery to the trunk" and there are threads on pretty much every flavor of car out there . I'd also run the same gauge back up to the engine and a short strap to a good frame location near the trunk.

+1, I wouldn't go smaller than 2 gauge, and to be extra conservative would go with 1/0 gauge. I also wouldn't use wiring designed for buildings, wrong strands and insulation.

Sorry I got it wrong I meant 50mm2 cable -> AWG 0. SORRY.

We use metric system so I made mistake...

And I used highly flexible rubber cable.

6GA wire is wayyyy too small. I used 2/0 welding cable to make my battery cables and it's in the stock location.

Here's a Moroso 2 GA wire kit and a battery box kit. You should also run a disconnect switch as well. If you ever go to a drag strip, it'll be required.

Full disclosure - I work at Moroso. We do our best to work with vendors in the USA wherever possible.

Yes, 50mm-squared is close to 1/0 wire, good choice.
