At that price, be it a good price, they would want to be life long guarantee.

These batteries have been widely discussed on another forum, with a thought by most that these batteries are far to light to be genuine 120Ah, but closer to 90Ah then 120Ah.
Everything has a standard weight, these lithium batteries weigh in at 11kg for 120Ah whereas a quality battery from another company weighs 12.6kg for a 100Ah LFP battery, which would equate to a 135Ah+ LFP battery is it was sold by IW.
Some people haven't cared that they have been duded but say that performance is what matters, me I want what I pay for. They are priced about right for a 90Ah battery so there is nothing special there.

I have just noticed that they have changed their weights for the battery after several months of people saying it is to light from 11kg to 13kg which is still light but where did they find that extra 2kg from? If this is correct they would now be about 105Ah my opinion only.

thxs Kebbin I noted they were stating 13kg in their ad. It seemed a good price for 120 ah but it seems that the old adage of if it sounds too good to be true . But then new technilogy slowly comes down in price with a new player trying to get market share my agm's haven't given up just yet so here's hoping.

At 12.8V they are lower voltage than most Lithium batteries.
A couple of weeks ago I made an technical enquiry about their BMS. I never received any reply.

I would say to check out previous posts and reports re this company over the last few years Especially about their VAST systems.

Gooday,'

Have not had anything to do with them but from those who have they are a NO GO Zone, used to be OPK but changed hands some time ago and anything they sell seems to be pretty unreliable

Knowing nothing of Lithium batteries

But..
As this question is in the General section of the forum

I offer the following information

The shop, and eBay seller "Access Antennas Australia" are offering a 120 AH Lithium LiFeP04 battery for around the same price

They are warning customers to do some research
They claim that some resellers, are selling lower amp hour lithium batteries, as 120 AH ones

Their 120 AH Lithium LiFeP04 battery weighs 16 Kg, and not 13 Kg

Below is a link

Again, this battery is only 12.8V nominal and it has a maximum continuous discharge rate of only 50A, which is insufficient to run heavy draw appliances which is one of the common reasons to spend the big money on Li.

Even the 120A for 10 seconds is less than you can get from a 120Ah AGM which is not designed for high discharge rates.

Thanks for that explanation, Peter

That was someting that I was unaware of

As I have no need (at the moment) to use 240 volt appliances, and knowing that my AGM batteries are sufficient for my current needs

This is the main reason, I have never really researched Lithium batteries in depth

I did like the way, that the people in my link, put their argument about other resellers up, selling 90 and 100 AH as 120 and 130 AH batteries
