Good to read some one is asking for advice on a "quality product" without asking for it to be the very lowest priced as well...

Your's is a Simple and EASY question to answer and is based totally on my own experience with a previous Smart Solenoid and electronic Piranha system on the same vehicle.

ROTRONICS
http://www.rotronics.com.au/4wd.CaravanApplicationSelect.htm

As for batteries:
as you are running the fridge, then the advice of ALL battery manufacturers specifically state that DEEP CYCLE batteries are made to handle long slow discharge, same as you get from a fridge, and a starter battery is designed for a shallow quick burst of power as used by the starter motor, but you will find some people who claim to know far more than the battery manufacturers and will inform you that a starter battery will be ok, but they neglect to mention that a Deep Cycle would be far better suited for the job... price and also the method of recharging the DC battery has something to do with it also.

Another point to remember is that the recharging of the DC battery has to be done as specified by the Isolator and battery manufacturer for best results.

For further confirmation phone any commercial leasing company that rents out “Winnabagos” and similar Mobile Homes and see if they use ‘starter batteries’ as Aux batteries in their vehicles.

I fully agree with Mainey's comments. Been running deep cycle batteries with a 'Rotronics' system for years, & as you said if you don't mind the expense then also go for a decent solar energy setup (at least 120watts) & you will have a good re-charge system for your deep cycle battery. Cheers

Cobber

I think you've just opened a can of worms! That's like asking which is the best fridge!!

Have a look here... just one set of views from a small Brisbane company. They just did my 100 series using System 7 (see brochure):

Plunger,
He did ask for... the BEST
Yes and without reference to price, this is a big change on any 4wd forum!

I believe Rotronics is the best battery isolator system available!!!

The BEST “performance” fridge is the.... Reefer Premier

0f course some-one without a Reefer will always disagree
-unfortunately they have never used one to know the facts

Therefore their idea is only one sided and biased in the negative.

How can any-one make a valid and credible comment on any product they have NEVER used, and probably never even seen, wether it's a battery isolator or a fridge??

I have a Piranha DBE-180S set-up on my 80 Series, it has worked faultlessly over all sorts of terrain. A solar panel set-up can be hooked into it so you can charge the auxilary battery on extended stops. It's like everything though, people have their own preferences and experience with pariticular brands so the best thing you can do is research and sort through all the bull and buy something that you are happy with.

Brad, there is nothing at all wrong with a Piranha DBE ' S series' Isolator, as an isolator -

I needed to be able to simply charge my Start battery as well as the two Deep Cycle batteries from the Solar panel, and the Rotronics allows that, the Piranha does not, also the cable lenth can be lengthened on the Rotronics, not on a Piranha, yes just simple things but important to me.

It's no good being the richest corpse, enjoy it while you can!

Mainey,

Interesting comment you have made here.

I also have a Piranha DBE "S" series Isolator and although I have never had the need to charge the starting battery via my Solar Panel, I would merely connect it directly to the battery. Easy as!

Everyone is going to have their own opinion based on their own particular criteria and experiences.

I actually had an initial problem when the Piranha was installed, but the fault turned out to be due to a faulty installation (bad earth connection) and not due to the Isolator, or Battery.

All of the leading brand Isolators, be they Piranha, Rotronics, Redarc, etc. will do the job they are designed to do and that is to protect the starting battery from discharge to the point that you cannot start the vehicle.

Any additional "features" of individual products are merely that, features.
Not many people would need the ability to charge their starting battery "through" the Isolator rather than simply bypass it.

My personal opinion of course.
Bill

Sand Man, My Solar system is installed on the roof and stays there with the cable going into the roof, via a marine quick-clip connection, with the cable then running between the hood lining and the underside of the roof, out of sight and out of the way, connecting to the Steca Solar regulator and with all cables still out of sight and out of the way going to the Deep Cycle batteries and the fridge also, so it would be a pain to disconnect any batteries or Solar panels as all the cables are all 'hidden' and it only takes 5 seconds to connect the mini 3 inch 'jumper cable' to the two Rotronics Isolator box (+) battery connection bolts.

However, because I camp for extended periods in the bush & beach and by leaving doors open etc causes some minor start battery drain.
I use the two (+) posts on the Rotronics, (which are not on the Piranha) to connect the Start battery direct to the Deep Cycle batteries via a small 3 inch 'mini jumper lead' every few weeks, and all three are charged by the Solar system at the same time.

A major point you did not mention is that the Redarc Smart Solenoid system, which I once used, is recomended by the manufacturer to be used with two 'identical' batteries and not two different batteries, such as a Deep Cycle and a Starter battery, hence the reason I had to have my solenoid replaced to achieve a full charge to the Deep Cycle battery.

Yes, as you say they do connect and also DISconnect the Starter battery from the Aux battery to avoid Starter battery drain, BUT there is more to an Isolator than just DISconnection!

Both Piranha and Rotronics actually specify their systems will work 100% with two totally different batteries, however Redarc actually specify the two batteries should be identical :-)
(that's not an opinion - but a fact)

Thank you ACDC for changing your tune.
As everything including the cars we fit dual battery systems to come from Asia. Including the the Asian Engel fridge, Asian Inverter, Asian Radio, Tv, Laptop .... need I go on.
I don't pay Asian prices and I'm sure Engel won't like it if you tell them their fridge costs $100 to produce in Asia. Asian components only form a small part of my systems which carry a full 12 month warranty. Most parts are Australian made including the labour all joints are soldered, sealed and fitted with heat shrink.
I'm sure it won't be long before we all need to learn to speak Chinese but until then lets enjoy the great outdoors and each other.

Happy New Year.

Regards Derek.

I bought one of Derek's systems from him on eBay for a song.

Twas easy to fit. Has worked flawlessly with a deep cycle gel battery I have and is running my inverter driving battery rechargers and computers.

Everything I needed without going over the top.

Every single one on the market has + and -, and you will get all sides here which can be good, but can take months to decypher the bollox from the facts.

Rotronics if you contact them will send you a CD with their gear on it. You can have a look for yourself.

There are probably 1040239840293402398 other threads on it in the past, so have a read back through.

I have the Piranha system in mine, and it has worked perfectly for 3 years. I would get it again, or keep it and put in next car without fail.

Good luck decyphering!

G'day cobber, as you've read, everyone has given good advice and recommendations. I too at one stage last year asked for the same advice and recieved many responces on brand and price. I think the best advice I received was to make and fit the dual battery system myself. After going to my local battery dealer and armed with the products I needed, with his help(read advice) I successfully fitted the battery system. I run 40L fridge(continuos), compressor and accessory interior lights. The system cost me less than half the price of Pirahna and ARB, included in the price was a replacement cranking battery. Hope this helps, give it a go it is not rocket science....good luck

Mike, you say "the Rotronics fitted to my LC100 blew up TWICE"

Don't you think it could have something to do with the installation method to have TWO (one would have to have been NEW & still under warranty) battery isolators "blow up" in the same vehicle?

I would have been talking to Rod at Rotronics and getting the correct installation information from them when the second NEW system "blew up"
I’m positive they would have done the right thing about your isolator problems and you would have a decent system, and yes I can say that because I did have a Redarc system, but found it would not work correctly with my Deep Cycle battery, so I sold it and replaced it with a Piranha electronic system.

Maybe you and your mate are just really "unlucky"
Don't suppose either of you win tatslotto too often then?
