does a LC 200 series need a 3rd battery to run an Engel fridge?

I am in the process of purchasing a new 200 series, I know that it has 2 batteries but have been told that the 220 volt plug in the rear only works while engine running. Is this correct?
We bush camp and use a solar panel with anderson plug to charge 2nd battery in our patrol for the engel.
I was hoping that would be the same for 200 series. What do other 200 series owners do?
Thanks Hugh

Hugh go and join the Land Cruiser Owners web site, Heaps of info there. Most split the two batteries as you only need the one as a starter battery. You will need an isolator between the two so you do not run down the starter battery. We had an auto election do our cruiser. Like I said, has heaps of info. The 200 is a brilliant car, enjoy. Kevin

Take the advice from Kris and Kev.

I'm a LC 200 series owner and shortly after purchase of this car joined lcool. It has lots of sound practical advice (wished I had known about this site earlier).

After reading on this site what others had done I decided to split my two batteries using a Redarc 1225 DC to DC charger (this unit had an input for an external solar panel). I run a 60L ARB fridge/freezer, plus other electrical's from the auxiliary battery (which operates all the time including when the ignition is turned off).

We have camped for several nights in the one spot without the fridge stopping and most importantly the start battery has never let me down. You can of course put a jumper lead from the aux to the main battery if you have difficulty because of low on charge.

This is my 4th Landcruiser (if you count my first Toyota, a Prado) and is the best machine of the lot by a long way.

Hi Bush Camper

The plug in the rear does only work when engine running. I had mine wired to be constant live.

As for splitting the batteries. I have a Sahara and been told that it needs both batteries to start, therefore splitting isn't an option.

Hi all
It is possible to split the 2 batteries in the 200 series, however to ensure correct starting and computer operation you should replace the left side battery with one of sufficient output (ie 700cca or better), the right side battery can then either be used for auxiliaries, or a dedicated deep cycle battery fitted for you fridge etc.

Should you use a suitable relay (100a Redarc or similar) and cables then you can also use this second battery as a back up for jump starting if necessary.

I have this system fitted to my 200 series 60th Anniversary TTD, and it works well.

Due to the reduced voltage of the charging system in these vehicles it is necessary to use a 12v to 12v charging system for the caravan batteries.

Hope this helps.

By the look of posts above it may be worth splitting the current two and installing a third in parallel with the "non-alternator" one already in the car. Link them with a Redarc 200 amp isolator/switch.

We run two fridges and that's what we did in our 100 series TD. No worries camping for two days without any charging. Almost full charge left in the starting battery.

For piece of mind and not a huge cost I would fit third battery,(if inside your cruiser an AGM fully sealed.

Batteries are nuisance things. Expensive and unreliable the less you have the better.
2batteries are a neccessary evil. 3is just inflicting cruel and unusual punishment on yourself

You blokes have magnetos fitted instead of the cursed battery ?
I have two batterys under the bonnet and two AGMs inside the car to power my 80litre Waeco.
The second under the bonnet separates from the first and the two in the back separate from the front.
One battery may be fine for people living so far south that it hardly works but up north you need batteries.
I have never had any problems at all in eight years other than when originally done by the leading offroad retailer in Oz, yes they make bullbars too.
I wired them myself as the "expert fitters" who live in the cities do not understand from my experience of them doing it the first time.
Little wiring good for nothing running hot and sloppy workmanship. If you do the research and do it right there is no punishment or unreliability and I do the gravel and tracks always before the bitumen to get away so corrugations are the norm.

Split the said before, and whether you use a third one or not....why not use a Traxide uses ALL batts to run the load, until the voltage gets down to 12V, then isolates the starter batt..lots more usable power....and don't worry, it still leaves plenty of capacity to start the engine..

I have had a 200 Sahara since Feb 2008. I split the battery 5 years ago. There is only one reason to put in a third battery. To make money for ARB or Pirhana etc.

There are already 2 big battery trays in place and the Drivers side Aux will fit a DC331 ( next size up from N70).

It is ok in the snow and Vic winter.

There is a Toyota bulliten somewhere floating around LCOOL advising against a 3rd battery as really sensitive connectors and wires have to be moved. They reccoment splitting the battery.

If Mr Toyota thought he could get away with only one start battery he would of done it.... less cost, less weight.

So why didn't he do it?

To me why decrease something that must of been done for a reason.

That's an easy one.

Toyota installs 2 x small 500cca batteries in parallel. You need to replace these with a larger 900 cca battery for starting and a large Aux suitable for you needs.

Why does Toyota do it this way? Cause it is cheaper.

To support what Boobook said,
The 70 series has the same V8 engine (one turbo instead of two, thats all), and it comes with one battery only
The 200 starts easy with one as well

I added a second battery to my Patrol when it was new for my power hungry fridge. I set them up in parallel to cope with the high drain from the fridge which is recommended by the fridge manufacturer. Most fridges, as mine does, now have a battery cut off voltage that can be set to stop the total drain of the batteries so to allow you to start your vehicle. With 2 batteries at 11.5 volt cut off, you still have plenty of starting power so i have never seen the point to add a Redarc type isolator to keep one battery only for starting. I have had this system since 1999 over 2 Patrols and never had a problem. As we have a roof tent and is not always easy to pack up and go for a drive to charge the batteries, we simply run the engine for 20 minutes at idle, generally in the afternoon, and this charges more than enough to get through the next day. It also gets the engine to normal operating temperature so allows us to use the engine mounted shower daily. The amount of diesel used at idle daily seems to be very small for the dual purpose of recharging the batteries and the shower use. Engel fridges are not high power users from what i have read so a parallel battery system would be perfect for the application. Michael
