Lots of potential answers here.

The first thing I'd say is it is very easy to do this work yourself. Quite apart from saving a lot of money, the big advantage is understanding your system and being able to modify or fault find it in the future.

The Redarc isolator is an excellent product, well proven and not expensive. I've recently installed one in my new 4WD.

Whether you do the job yourself or not, using heavy enough cable is the key to success. I suspect this is the biggest cause of poor performance in dual battery / 12 Volt systems in 4WDs and RVs.

This Explore Oz article is a good place to start:

Doc,

Do a search with the search function above. There have been a quite a few recent posts regarding dual battery systems.

Cheers Mick

G'day Doc,

Can you please supply more information ie
What will you be running off the system
How much room do you have under the bonnet
What type of camping will you be doing.... fixed camping for more than three days or always mobile?

FWIW best to keep it simple.

We have three Bosch Gold batteries, two under bonnet and one in the CT.... not connected.. yet. A small job to rotate the three to keep them in good condition. A simple solenoid system for charging was taken from the 60 and shoe horned into the 80.

Good luck with your project and I hope the information is helpfull

Cheers,
Wayne & Sally.

Sorry about that, its my first time on the forums and I was a little nervous. Anyway I have a 2005 Mitsubishi Pajero Exceed 3.2 Turbo diesel. There is plenty of room for the other battery. My intention will be to run an engel and lights whilst fishing and camping. What do you run from yours when your out and about.

cheers

The make and model of the 4wd would be a reasonable thing to include in your request.
Otherwise its like trying to do brain surgery over the phone whilst wearing a blindfold

One of my mates has one of these and he had a hell of a job to fit a second battery.
He ended up shifting some stuff and putting an Optima against the firewall on the passengers sidein a cradle he made himself.
I couldnt see anywhere that there was "Plenty of room" for a second battery

Graham last time I looked under my bonnet there was "plenty of room" for a second battery.

All I am after is some suggestions that I can do some research on. I didnt realise forums would be so frustrating!!!!!!!!!!!!!

cheers

They are only frustrating if you dont ask the correct question or fail to provide as much information as possible
.
Your first question was as vague as they come and as one poster said "Do a search on here"

If you did you would have found countless threads asking the same question and countless answers all with a different opinion.

The article provided by the site gives an insight into the ins and outs of the subject.

Even the difference of whether or not there is room is just the difference between opinions of what is enough and what is not.

I will however check which motor my mates has but it is a 2005/6 Exceed diesel.

Not being rude but had u posted a question like


""I have a 2005 Pajero Exceed diesel and would like to know which dual battery system is best and also what type of battery should i use.""
Something about why you want it EG to run a 80 ltr fridge,etc also helps as to battery capacity etc

You would have got more informative and correct answers.

See what I mean.

Cheers

You know, odd as it may sound the best answer to your question is "the system that does exactly what you want"

So maybe if you can tell us "what you want" someone can actually answer your quesion!

Not having a fuse close to the + terminal on the Auxiliary Battery is a fire hazard.

The manufacturer has already provided fuses near the original battery.

You ask : "any suggestions on the *best type* of dual battery system I should put in"

Not to insult you I will suggest a *mechanical solenoid* is inexpensive, so yes will save you some money, but an *Electronic battery isolator* will make you happier, but your wallet lighter :)

The 'best' battery is an AGM Deep Cycle (or two)

G'day Doc,

Can't believe there's another doc out there, I'm stoked!!!

Doc,

it's not difficult.

Just think of your first vasectomy (or reversal).

You know. You identify tubes (cables) between two kahonies (batteries) and make sure the little taddies (electrons) can run along unimpeded or not.

Now I bet you weren't nervous the first time you hovered over some poor unsuspecting bloke's family jewels with your scalpel.

cheers
