They look brand new.

Re: Links to lifepo4 battery cells

Yes if they are indeed 700Ah capacity, $4 per 12V Ah delivered is a great price for bare cells.

Maybe start a build thread if you want to discuss commissioning process, breaking in, benchmarking the starting capacity FFR, balancing, BMS etc.

compression plates + straps is importantClick image for larger version

Re: Links to lifepo4 battery cells

A friend of mine is looking to make a LFP house battery, and I recommendet him to get in touch with Julia for a quote.

I wrote also an email to Winston asking for a refference on Julia's business to check first, they answered promptly within one day and confirmed she is a certified reseller and works close with them, so all OK, I guess.

Great to have a good contact to the manufacturer this way.

Maybe you need to check your spam blocker if you cannot receive mails from Winston CN.

Re: Links to lifepo4 battery cells

I think that it is important to give credit where it is due for attached photos. And as we can see Rod's (Mainesail) build of his 400 AH bank is outstanding.

Darn, and his shop is much cleaner than mine.

OTOH - here is a photo of my 700 AH bank in the early stages of the install. The plates are 1/4" aluminum and the angle brackets that hold the bank in place are backed with some big washers to the ply base.

Thank you for recommending your friend to me, CNB.

And it's good for everyone here to know that we have been verified ok in this way also. Thank you.

Re: Links to lifepo4 battery cells

Wondering if anyone has experience or information on Gee Power. They sell prismatic cells lifepo4. I don't recollect them mentioned here.

https://battery-system.com/
https://battery-system.com/product/3...prismatic-cell

Also - what is GTK batteries? It does not appear to be a manufacturer.
