Max Amps Pulled From Battery / Cable Gauge Required To Relocate Battery To Boot

[JustinP]

I searched for a DIY guide on relocating the battery to the boot, and surprisingly couldn't find anything!

Can anyone advise on the minimum cable gauge required to relocate the battery to the boot? I have a heap of 8AWG cable (61Amp capable) which I realise is probably not going to be sufficient, but I am just wondering if I run 2 of the lines if it will be enough?

Cheers

Justin

depending on the quality of the cable i recommend 2awg as a minimum preferably larger,

i measure a starter on a v6 commodore 160amps on cranking. which has lower compression so i assume less work would be needed to crank.

Bigger the better!!

50mm2 0awg I would do personally.

I run the factory 35mm2 + 70mm2

Cheer's for the responses Looks like even 2 x my 8AWG wire is not going to cut it!!!

I think I will leave the battery relocation for another time.

Shame you are so far away, I have about 50m of thick battery cable here...

It is a shame, but thanks anyway!

2ga is more than plenty, it is also the same as the -ve line from a mig welder. Hit up BOC gas and just buy some welding cables, works out cheaper than 2ga audio cable

My Gtr had the battery relocated to boot, used 2gauge cable, never have a problem with voltage drop or any other electrical problems (apparently these cars are voltage sensitive)

6 Cyl Starter motors usually draw between 200-400 amps. No amplifier wire is going to cut it. You need minimum 2 gauge battery/starter cable. It's about $10/m at repco from memory

welding cable works out a tad cheaper if you have a trade account

[The Dan]

Also don't forget your starter motor will draw more current in winter and also when the battery is lower in voltage. You need to account for these factors so you don't catch things on fire. Safety first

Haha yeah. They look at you funny when you ask for 8m of it though

I used 0 gauge audio cable. And I ran both earth and positive. I didn't want to earth though the body. U can't go wrong with over earthing.

Cost alil bit, but I hate wiring probs so I just over killed it so there won't b issues.

I once attempted to start mine with 2x 4ga cable and it would barely turn over. 2 gauge is a bare min in my oppinion.

What are people using for distribution blocks once they have relocated the battery? Having a bit of a look at options for such things at the moment.

stereo components really.. you just need a good ANL fuse & holder that that's it.. don't waste your time with anything else
