Trunk mount battery questions - Lateral-g Forums

Hi guys,
I was hoping someone could help with some questions.

I want to mount the battery in the trunk,

1) what is the best mount to secure the battery
2) best place to run the cable to the front (inside the interior or out)
3) what cable should I use

Thanks

don't know if it'll help but I posted a blog entry about my trunk mount battery. I bought a cheap ($17) batter tray from speedway motors. bolted it to my trunk floor. ran the neg. cable right through the trunk floor and bolted to frame rail. routed the pos. cable through the trunk and under the rear seat, drilled a hole to pass it beneath the car and ran it the rest of the way to the engine bay...

i used a #2 welding cable from battery to starter, just make sure your block has a good ground to frame

I ran 2 grounds. One goes right to the body, the other goes to the block. It's on the overkill side, but it's nice to know that a few extra dollars invested here won't cause potential issues down the road.

I would weld a stud or short hex-head bolt to the chassis rather than trust a bolted-only connection not to oxidize/corrode between the bolt/stud and the sheetmetal.

On the avatar car (full-frame) I ran a short length of threaded rod through the floor (with nuts and star washers) and welded a short hex-head bolt to the frame rail. Ran one short cable from battery- to threaded rod and another short cable from the outside of the sheetmetal to the bolt. Welded another bolt to the frame rail in the engine compartment. No starting problems, ever.

It's only 'overkill' until doing it in a less fussy way doesn't let you start the car.
