Default DIY dual battery: Tray modding and reusing factory battery

Here is my completed dual battery setup. I wanted to reuse the 10inch factory battery. I've used the outback accessories tray as it is made from thick powder coated steel not flimsy pressed steel like the piranha. Plus it was alot cheaper!! Only problem is it only takes a 8inch battery but by grinding off the end I could fit the 10inch factory battery.

I've used redarc controller, bussman 90amp terminal fuses. The rear setup is 15amp manual reset circuit breaker mounted on dual tray, cable to the rear to terminate into a hella plug beside factory cigarette lighter. The second battery is a 12 inch trojan 115ah deep cycle.

Looks fantastic mate.. Wish I was that handy... I was thinking about getting the prianha 10inch tray which wont give me a battery with good ah.. but didn't even consider moving the factory to the back... what a great solution... The Trojan battery fits in the factory tray no worries I take it? But I wont be attempting this myself. I have had quotes so I might see what I can get sorted.

Thanks

Scott

Well done looks good. But what makes you think the piranha tray is pressed? By my recollection it is about the same gauge ( maybe even heavier ) than what you have used. And it is certainly folded not pressed, not that, that really makes a difference.

I stand corrected. The piranha tray is folded. If you look at the two trays side by side you will see how much stronger the outback accessories tray is. And it is black powder coated. My only criticism is that they could of made the plastic battery clamp that holds the battery in the center a bit stronger. The tray bolts directly to the engine bay. It had several predrilled holes which I used to mount my circuit breaker and redarc.

The 115ah trojan battery fits perfectly in the factory tray. Cost me around $330. The model is 27TMH.

I did it this way as I wanted to reuse the factory battery as well as fitting the biggest deep cycle in the factory tray. The bussman terminal fuses were not the cheapest option but they were dead easy to wire up and came with protective caps.

Hi former toyota man, what Pajero do you have?I have the NT and wasn't impressed with the size second battery that could go at the back... so your solution is great...I had a look at my starting battery last night and there doesn't seem to be much movement for the original cables...how did you go?

The TJM tray is also an excellent auxiliary tray (if you can find one) considered one of the strongest as it is nearly a full box and sells for about $150. Given the original is plastic and nearly always fails I think any of the aftermarket in metal will work

If you search for posts started by HSVrangie he has posted a drawing of a replacement tray for the OEM battery position that you can make, this allows for a larger again 13" battery to used in this position after moving the start battery to the auxiliary try.

Neat idea. Are you going to beef up the factory tray (I see reports of them breaking).

Where did you source the bussman terminal fuses from?
