More pondering on a dmax. I had a look at one yesterday and wondered whether or not a dual battery system was possible under that bonnet. Has anyone fitted dual batteries to a dmax?

A mate has the latest Colorado dual cab and he has fitted his Aux battery on a battery cradle he mounted on the wheel arch in the tub, LH side.

He had a canopy fitted first though. It is up out of the way and is probably the best place given what is under the bonnet and the lack of space available there.

Cheers, Bruce.

I am waiting delivery of my Dmax and investigations reveal that there are no problems doing so. TJM, and apparently Isuzu, say that the Dmax does not have a 'smart' alternator. TJM fit an under bonnet setup using an Odyssey battery.
Have a look at the Dmax Forum and the 4wdaction Dmax Forum. These forums have info on DIY dual batteries.

Here is a link to a dual battery tray that I know fits

Also as stated above the Dmax does NOT have an ECU controlled variable output alternator often referred to as a smart alternator. So really easy to wire up an aux battery.

Someone produces a battery tray that sits on the chassis under the tub.

Mike,

I had a battery tray for my 79 series, but as it involved moving some parts adjacent to the oil filter, I gave it to a nephew and fabricated my own from an old truck mudguard.

Sits at front of the tray, just behind the cab, and has caused no dramas over about 5 years, and some rough station roads. Don't know if the photo below will give you any ideas?
