I was just following this thread but I will follow up here and let you know when the batteries here I and what's going on what shape but they seem too cheap to be true which is I don't know. But there's some reason there's a ton of these to be sold new and used
They are surplus cells from hybrid buses. There are a ton of them out there used.
These have been selling for several years now.
My last purchase in January I got them for about $2/cell at batteryclearinghouse.com.
His prices have more than doubled since then.
FYI date-codes on my last batch varied from between 2013 and 2016.
Of the 80 cells I've purchased I've only had two bad (they lost their seal)....ebay vendor replaced them no questions asked.
I ended up selling about 30 on craigslist for MORE than I paid for all 80 cells!
PS: Cells I bought are in US. It took only a few days to get them from batteryclearinghouse.

Ok order on Friday and received on Thursday . 36new 4 used of the four one has a small dent like a corner of a plastic box was indented on it . Yes they have holders so no touch and can be bolted as one with threaded stock. They are a little big for most bikes as 20s and 20s2p ? May just use as 15s 2p for 1,500watt dd motors like a leaf or bbhd stlye.

How are you all attaching these together? I'm going with grommets for a 3s2p pack I'm making for a general purpose 12v bank. I'll use it for starting a pump, a lawn tractor and probably my truck as well as running an inverter and possibly other less amperage use. My next packs I'll probably modify Mike Poff's pack brackets for my needs and use aluminum and bolts. I was wondering if anyone tried spot welding or other methods and how well they hold up. I was thinking 3D printed clips or something for easier replacement or reconfiguration.

Anybody got a datashet for this cell? i have seen it... The real sheet.. did not save it to my drive.

They are maganese Li-ion? something likte that? i do not think they were "Bus EV " cells...I think that is hearsay and wrong.

I have heard they were test cells that were never used.. the new batch... from BHU.. info.... but still no sheet.

Gonna build mine soon.

LiMn?

That has pros and cons, but very safe and long lasting, as compared with LiCo.

Probably LiNiMn I’d say. Good performance and about the same cycle life as LiCo.
Make it fool-proof, and I will make a better fool.

If you mean the cell this thread started about, SPIM08HP, then it's almost certainly somewhere in one of the posts about it
search.php?keywords=SPIM08HP&terms=all& ... mit=Search
but I don't know which one. Too many for me to look thru for someone else. ;)
