dual battery wiring and mounting help.

[BLKWDW]

I've bought a dual battery system a while ago but havnt got it fitted up properly yet. I bought it just before xmas and as the power cable i got with the kit wouldnt reach the battery in the boot i just sat it on the backseat floor for the trip. I got back and bought a longer cord but without measuring how much i need and guessing the new cord i bough pulled up short as well.

So i was gona use the 2 cords to span the difference. But i still cant have the electronic battery controller mounted in the engine bay . Will it be alright if i mount it in the cabin probably within reach of the drivers seat at all? That way i can reach the battery in the boot plus i can reach the button on the electronic controller to jump start the car if i get a flat from in the car. Will this work. Was probably gona mount it on the side of the centre console or will it need to be higher. Biggest problem i can see having it there is if the car fills with water it will be swamped.

Question 2 is the other problem i got is the 2 cords i got are different sizes. One is a 14oammp power cord and the other is a 215amp power cord. Will this cause any problems and if not will it matter which way i run the cords. Like am i better having the 215amp or 140amp from battery to controller and then from controller to second battery.

I would be using the 215 amp for the longer distance run and the 140 for the shorter run. I can't see a problem having it mounted in the cab but I was seriously think about some sort of protection around it so no one gets zapped. Also make sure the battery is a sealed battery if going in the cab. Yendor will be the most knowledgeable with all this, if totally stuck pm him!

I cover it with something yes but still gotta find the ideal spot.

This is the battery i'm using. Was going in the engine bay but wont fit and with how heavy this thing is could only imagine it would crack the wheel arch

Battery is fine for inside the car... It will actually last longer in the troll instead of engine bay.

Another member has just fitted a 3rd battery in the cargo area, might be worth searching to get some Ideas
very neat install as well. originally it was there was because no room under the bonnet, but heaps of Pics and step by step directions.
look in DIY section under 3rd battery install, or someone better than me may be able to post a link.
As for your cable start at the battery with your thickest and step it down, don't forget an inline fuse or thermal cut out close to
the pos on battery. run all cable in plastic convoluted tubing and cable tie cutting cable tie with stanley knife not side cutters.
No sharp edges that way, make sure battery is secure, dont want any missiles

Thanks mate do you mean the second battery or starter battery for the inline fuse? It will be bolted down in the back of the gq. Can you reccomend the best place to mount the dual battery controller in the cab?

[rottodiver]

I can't really help on that on but thought I would give you a reply, I have not fused any of my main battery cables and I have a triple battery system, everything I have coming off my batteries is fuses, I am interested to see if you get a response from yendor on this questions!

In line fuse to both batteries mate

[rottodiver]

np99 what size?? and also considering the thickness of the cable i guess it would have to be a circuit breaker?

What brand controller is it?

There's more room on the passenger side, either in the kick panel or even up behind the back of the glovebox.

For a rear battery installation I would recommend using circuits breakers, one mounted as close as possible to the positive post of each battery as well as conduit over the cables.
