Old batteries, price per Kg?

Have you tested your batteries? My old bank had only one dead and three good batteries after I thought they were gone, those good ones might be worth a bit more per kg

Yes, two out of eight have gone noticeably bad and the entire bank does not hold a 4H30 load shedding period on a light load anymore. I could build a new bank with four 'seemingly good' ones but it defeats the purpose of having a large bank for such long LS time periods we have. It's a pity, they were costly and if I sell them to someone else they might just get 6 months or a year out of them. I could build a small trolley... Hmm?? Or just take the money and recoup some loss in favor of the LiFePo4 battery waiting installation.

I’m in a similar situation with some extra batteries after i got a pylontech. I don’t want to sell them as scrap, but also don’t really have a use for them right now.

I see a great opportunity for second life battery’s for newcomers who do not have funds for brand new batteries, or someone just doing test runs on solar installations where any 48V bank will do. Similar to what is done with the old lithium's comming out of electric cherry pickers and access control equipment, these are being re-branded as second life.
