Hi Ash and Christina,
                             thanks for the info. I couldn't bring myself to fork out the money for any more lead acid batteries without more analysis. Best wishes from down under, B and B

Batteries: We've been looking at replacement Lithium batteries from iTECHWORLD, located in Perth, W.A. Link provided.
https://itechworld.com.au/products/100ah-12-volt-1000-cca-lithium-battery#

What interests me about these batteries is the ability to install their Lithium batteries without the need to upgrade the battery management system in the camper. Which everyone knows is a significant cost.
Each Lithium battery has its own in-built battery management system (patent pending). So it's a simple procedure of removing the old AGM battery and installing the new Lithium battery. Hook it up and you are off and running.

I currently waiting for a freight quote from them for 2x batteries to Queanbeyan. Yay!! Free freight. Excellent.
Alternatively, if our batteries are okay, and will get us across to Perth, then I shall look to swapping them out in Perth in August. 

Worth a look, heh. 

Cheers, Filbee56

Update 05/6/19: ordered qty 2 of the iTECHWORLD lithium batteries........hopefully they arrive this week.

I have just looked these up and also spoken to iTechWorld.

They look terrific.  3 Year warranty, free shipping and gauranteed even under the bonnet of a car (AGM batteries overheat and don't last long under the bonnet, we are on our third AGM after five years).  Will easily fit in to the 490.  The only issue I have is fitting one as an auxilary battery in the Prado Kakadu with lots of underbonnet stuff.  I will have to look in to moving some pipes to fit one in.  Will post if I can.
Looks like a great product.

Hi Klaus

Let me know how the batterys go

My AGMs are still doing ok but it's only a matter of
time before they spit the dummy.

I replaced my 2 105amp AGM batteries with 1 120amp lithium. For the price ($900) it was a no brainer. Would have cost nearly the same for 2 AGM batteries. Fast charging, loss of 40kg, is the start. Wouldn't go back to AGM now. Have had it in my 390 for nearly 12 months. Charging it with Redarc BCDC25 on lithium setting (used Projecta before never again, both AGM charger and thier new lithium dedicated charger)

Lithium Battery upgrade. This is the first major weight removal from the trailer since purchasing in mid 2014 we seem to keep finding new things we need!, so we place, bolt or rivet them onto our trailers .
So I have just removed about 60kg of AGM batteries which like the majority of us had them located each side of our trailers just in front of the wheel arches on the 490.
I decided in the end to go with 2 x 100 amp lithium ion phosphate batteries (this was just in case I ever wanted to put them back in the original spot, rather than 1 x single 200 amp battery)   from a company in Brisbane called Satplus, batteries cost $695 each . Ordered and delivered within a week ,great service I think and they weigh approx 13 kg each. So after some thought I decided to not just refit them where the old AGM`s were and re-use the existing charging system but to relocate them and go with charging equipment that is lithium specific .
A new electrical board was made up to fit in the front box (as no diesel heater is fitted,its in the offside rear pocket) this is now fitted with Lithium ion phosphate specific chargers. A  Victron 12v 25 amp 240v charger IP67 , an Renogy 12v 20 amp DCDC charger and mounted in side the trailer mounted under the original control panel is a 20 AMP mppt solar contoller to manage the 2 x new 110 watt ETFE panels on the roof with an inline 30 amp reset able circuit breaker on the positive connection down stream of the controller.
all cabling running across the trailer to link the previous batteries was removed plus the cabling on the kitchen side was all re run. As I had already replaced most of the original wiring before as it was either too light or just messy. Some of it I re used, some I didn`t. Mounting up the chargers , shunt,  negative buss bar and positive terminal box was way easier doing it in the shed on the bench than trying to do in situ. The new control panel has a clear perspex front with a 50mm hole over the re set able circuit breaker and the batteries have a 12mm close cell foam pad and a perspex cover. 
I now have the batteries sitting side by side and connected in parallel  using very heavy short cabling giving 200 amps, yes this has reduced the storage in the front box but in some ways this is a good thing as it made me re evaluate what I really need to store in there and do we really need to take with us  when travelling.
So far they haven`t had a full test by being away and self sufficient, so just running the fridge / freezer (set -14 deg C) and running the diesel heater for a few hours on and off over 24 hours the voltage never dropped below 13.2 v and the capacity never dropped below 100 % in the past I would normally loose 20% just running the fridge for 16 - 18 hours over night.
I`m still trying to get my head around how lithium works, in my scenario at first I had to recheck my battery management  system to make sure I`d programmed it for the 200 amp batteries as nothing seemed to be changing as the hours ticked by.
I`ll give a review in a few weeks when we head back down to the snow again and camp off grid this time using both diesel heaters (air and the water heater) fridge ,lights etc  to see how they go and whether 420 amps of solar can top them back up during the day when the sun goes down at just after 5pm.
Nearly forgot to mention that the 2 x spaces where the original batteries sat are now storage bins. I marked out and cut 2 x openings which now store things !!!! not finalised what `things` will live on each side but I will,.. although wine bottles and beer were tested and fit perfectly.
 Cheers

G'day folks. I'm happy to report that the 2x 120amphr Lithium iTECHWORLD batteries that I purchased and installed back in mid-June have been performing extremely well for the past 2 months.
Firstly, the weight saving is considerable. Each 100amphr AGM battery weighed in at 37kg. And each Lithium battery weighed in at 12.4kg. Speaks for itself. The REDARC BMS was set to GEL, but you can leave it set a to AGM.
Once the batteries had initialised (took several hours), and fully topped up....via 240v charge, I then switched "off" the 240v and relied on the batteries for the following 24hr/ 5 day test. I switched the fridge/freezer "on" and, each evening from 5pm to 10pm, I switched "on" the internal LED lights. At the end of the 5 days, the batteries were down to 54% power availability.
This test was conducted in the garage, so no solar input. At the end of 5 days, I then switched the 240v supply back "on", and the batteries were back to full charge within several hours.
On our westward trip to Perth via Birdsville and central Australia (July/August), we were off-grid in Birdsville for 6 days. On the morning of day 4, we were hovering around 12.7v (from memory) and so I set-up the 150watt solar panel, and by sunset, the batteries were back to full charge. I have not used the solar again for the remainder of this trip because we were only overnighting for a maximum of 2 nights, but mostly 1 nighters.
So I can say that we are extremely pleased with the Lithium batteries, and can highly recommend.

Cheers Philip

Well its been a few months now since fitting  2 x 100 amp lithium batteries, so far they seem fantastic . Todate they haven`t dropped below 100% after overnight usuage and are topped up very quickly even during quite overcast skies and if not quite facing into the correct direction of the sun by the 2 x 110 amp ETFE solar panels on the roof. I have taken the large folding 200 watt panel also but haven`t used it on the camper only on the car to charge its second battery as the roof top ones work so efficiently .
I have over nighted with 240v power available a few times and having the ability to isolate the batteries and run the victron 240v charger as a 12volt stand alone power supply is quite a nice feature.
It seems lithium batteries have a very flat discharge curve compared to AGM so my digital battery monitor hasn`t dropped below 13.3v  so very impressed. If you`re thinking about doing this battery up grade I can`t recommend it enough . No more chasing the sun with a mobile panel and worrying about your batteries as the voltage decends towards the low 12volt range with no sign of good sun till tomorrow or the next day?
On storage I return home hook up the 240v power and recharge the batteries (if they accept it) then I`ve been disconnecting the charger and leave them. As I`m in and out of the camper amost weekly I just keep an eye on the state of charge but haven`t needed to recharge as its only the lights that may get turned on.
So all in all very happy.
Cheers

Couldn't agree more, mine never go below 12.9v when under load.

Our iTech 120 Lithium batteries have just arrived.
Since I am not a Sparky could someone give me some tips on the easiest installation.
Presumably the 2 lead acid batteries are also in Parallel so it should be a simple 1 for 1 swap? Am I correct?
Any help appreciated.

Yes, swap as you would do a new battery, just be VERY careful you don't arc the positive, they put out some amps!! Will melt a spanner if you are not careful, I use a rubber handled mini socket. And add a 50 amp fuse to the cable.
