Hi BOBBEAR,
I've only seen them advertised, some of the others may have knowledge of them.

Also look up RoadTechMarine - they have a 100AH battery for around $800 (I think you get $1 change). Which is the better, I don't know but our astronomy club in Townsville has smaller lithiums to what they originally would have to use if AGMs were being used (deeper discharge possible).

I'm certain the prices will continually go down.

Hi Warren....without wanting to get involved in a spit fight,I will tell you for free  that 100AH at $800 will be garbage.Period. Cheers

Don't listen to the stories of Lithiums less than 1K as garbage, those folks obviously haven't a clue as to "current" market pricing.

A year or two ago you would be well into a grand plus for 100ah but now you can get quality 100ah LiFePo4 for just under $600.

Sure there is all sorts of rubbish batteries of all types being sold, not just Lithium.

If you want to be sure what you are getting ask who the importer is and contact them and request internal photos.
Also, the cells of a 100ah LiFePO4 battery should weigh approx. 13kg and with the BMS and case the complete package should be approx. 15kg.

 

I don't have any affiliation with the following brands or companies, only that I have two of the 100AH (6439 100-12-80) in my van and am very happy with their performance so far.

So long as you don't want to run some over the top inverter, check out these units capable of a 0.8C (80amps) load.

Import company has been around for quite a while and offer 3 year warranty.

Here is a well known Melbourne RV battery reseller you can buy them from. Been around for years. They extend the warranty to 5 years.

Hi,
I'm writing this with some hesitation as I feel could be a few non-believers pop out of the woodwork, however this has been our experience with lithium batteries in the past 3 years. It all started with buying a caravan fitted with a 120Ahr AGM battery on a little slideout trolley which all up weighed 50kg and fitted in the front boot area. We were having huge towball weight problems so started with the removal of this deadweight. Located 2 "120Ahr" lithium batteries, one for caravan, one as house battery in towmobile. All good until we actually used caravan and found they were both faulty. Approached seller and a few months later we had money refunded for which we were extremely thankful.
Much head scratching and net-surfing and found CALB units 180Ahr for caravan and 100Ahr for buggy and costing considerably less than the initial outlay. Over 2 years on we are really happy with the performance and over a 3 week break in Nov. last, the voltage never dropped below 13.2v. Sure it is used sparingly, running a 130ltr Vitrifrigo 12v fridge, lighting and Wallas diesel cooker/heater about 5hrs a day. Solar input is about 250w through an Enerdrive DC2DC regulator and the buggy was never plugged into the system at all.

This has taken a good while to write as my keyboard appears to be jammed in low ratio, B.

 Hi BOBBEAR

If you type in " itechworld lithium batteries " in your browser

There is a forum (started April 2019), where they are discussing those batteries, it is now 41 pages long

From what I can make out, it may be a bit too early to say, if they will last the distance, but so far, there is only one bad review

Hope that this helps you out

I'm currently in the process of replacing my home stand alone solar battery pack. The AGMs have given up after 5.5 years operation. They have been charged correctly through an automatic system that has been pre-programed with protections in place.

The point of this is Warranty.

These expensive batteries ( 12 at 720Ahr each) were/are the weak link in the stand alone system.

The warranty for solar panels and inverter and controller is 10 yrs or more.

The batteries, even though they are a reputable brand from one of the world's best engineering countries, have only a 12 month guarantee (with conditions)and a 4 year pro rata dollar warranty. 

So I will not be replacing them with AGMs as they are still only offering 12 months guarantee (with conditions).

I will replace them with Lithium , with a 10 year warranty (with conditions). The conditions cover charging rates, Max discharge rate etc these are preset in the controller. and  are  logged in the history log that is downloadable in case of warranty claims. 

The Point.......Might be A bit long-winded but from my observations while researching Lithium is that good, reliable batteries have longer warranties.

So if you are intending to install Lithium in your palace, especially if they have their own management system, a longer warranty period should accompany, and considering the high cost of good reliable Lithium batteries,  it probably should be one of the most important considerations in the purchase. 

Cheers,

Chris.
