Great idea in having a Battery Talk Section.

Thanks!   Vic

Yup , Good Addition !!
I moved one of mine


Not on  desulfators?

On first Gen Tesla cells

These are not 2170 cells or the SI2170 cells

I Think it is a great idea to have a forum on batteries, as I don't follow the norm in Aussie and use Nickel Iron NiFe cells Which i am have great success with would just like to find out more information.

By the way, how are things going with your edison cells Herman?

Hi Mate

It is going well I am about to get another MidNite Classic 150 (new Second hand) to basically use it as follow me with another set of solar panels with 12 BX 65 which are being wasted on my lead acid Bank  Spec sheet is in the attached file it will be setup as 2 in series 6 parallel.

The intent is to simplify every thing and get as much charge into the NiFe cells as I can, but in short the NiFE cells are preforming exceptionally well, just wish the original installer did not under size it and gave me 800 or 500 Ah at least not the 240 ah which only gives me enough charge for 1 day before i have to start the generator.

You are lucky you got your batteries Herman!
One of my friends ordered some from a seller in Western Australia and paid his
$10,000 up front. The bloke went broke and Scott did his money and of course has no batteries to show for it!
I tried to get him to buy some trojans to start off with as we have a local retailer who does really good prices
and the delivery truck comes right past our property boundary (free delivery).
He is a pretty sorry soul at the moment. ::) :(

Hi Russ
Sounds like the the bloke I got my solar system from.
He offered me 20 x 1,000 Ah NiFe cells for $15,000 which was like woah that's cheap then the alarm bells started ringing so I said no, as it turned out he had already sold them and got the money and  just needed more cash, he is now in WA as well. 
With the solar system I have nearly replaced the lot bar the batteries which I will probably have to get larger anyway because he totally undersized them and gave us 40 x 240 Ah which runs well for one day then you have to run the generator if it is cloudy on the second.
So I am looking at 500 Ah NiFe cells as per the spec sheet(see attached) and the reasoning for the NiFe cells they are nearly indestructible, you just have one purchase, and have to replace the solution they say every 10 years but I have heard seven not the battery and they are no harmful to the environment unlike some of the stuff that is out there down side is the the initial outlay for them.
The supplier here is 24 hr solar who as just started here in Lismore like everything be aware of the new guy.

I dream of 2000amps at 24 volts in edison cells.
The only way I will ever be able to afford them is when I get my super.
But atm the rolls cells are working a treat especially after being purchased at scrap prices ;D
My only real concerns with the edisons is how long will the cases last?
Some of the original ones from what i have seen are/were stainless steel.
The way I look at is if the cases split then what do you have?

Never got to look at the cells CD as they went off gumtree listing quick.
All I can say is that we assumed the cells were edisons and that the cell cases appeared metalic and shiney.
May have been something else all together.
All the pictures of the older edison batteries seem to show metal cases for the cells.
Am I wrong?
