Thread: What Batteries - Dual Batteries

But what a fantastic accessory. I've already got an ARB dual battery tray on rear fire wall but the new arrangement would enable a much larger batter to be used as the rear tray location limits the battery size drammatically. I could also use the rear tray to mount an air compressor if I could move the battery to the front.

I have not installed the tray as of yet, however I do not recall seeing anything other than the jack in the box...

Mine is a V8, maybe there is a difference between the V8 and TD5.

I looked at the ARB trays but did not want to have close to 2m of wiring between them etc. and I did not want to fill up the space at the rear of the engine bay. As you mentioned it would be a good spot for a compressor.

Can I ask how much the ARB tray costs as a comparison to the one I sourced?

The Aedofab tray was $270 shipped to my door from the US.

The battery tray is sourced from the US, a company called Aefob. It was not cheap but it was delivered from the US to Brisbane within five working days.


Hey Chris, I cant find this company. You wouldnt have the link, or contact info?
This really does seem a good solution for me as well, I dont have a jack in the box.
Do you shift the ECU box as well?

Update: Found it http://www.aedofab.com/

Biggest difference...

TD5 has ECU there as well, V8 doesnt...

I bought the ARB tray about 2 years ago and from memory it was about $70. Their design has a good point and bad point in regards the way they hold down the battery. They use a vertical plate which has a horizontal lip near the bottom which pulls down onto a mating lip on certain battery designs. Thus there is only one shape/size of battery (from memory something like RD4) and a couple of brands of battery you can use. Battery size is limited both in width and height. You are limited to about a 55Ah battery. However the vertical plate acts as a heat shield from the engine having a 1cm gap between the plate and the battery. I've put in a larger 80Ah battery but I had to custom design a new hold down and it didn't cope with the heat well.

Always wire winch to the Main battery.

Why ?

I was thinking running it off the auxilary would be better, especially if your vehicle is not running for some reason.

Wouldn't want to flatten the main cranking battery.

Can I ask what size batteries people are using?

From what I can tell the Optima's are only 55AH batteries.

It wouldnt be too hard to make one up, I just didnt have the time to pull apart the car, measure and fabricate one.

As mentioned, I have seen dual yellow tops, blue tops and red tops used. I will check out the Odyssey Batteries as well.

DETAILED Pictures and measurements please! Particularly of the underside of the tray!

Arent there ECU relocation kits? If so, where do you relocate it to?
I like this idea, and have actually been trying to mock something up over the weekend. Bit hard without battery measurements etc. Reason why?. I want to stick a provent with heatshield in the right rear of the engine bay (where others are sticking battery)
