Re: [EVDL] NMC chemistry working voltage

Note the text in the ad:
“Do not use or leave in a car”.
So, if you plan on using it as solar battery then fine.
If you plan to use it in a vehicle, then you probably have no recourse.

The cell type and cooling method looks a lot like VW does (rectangular cells, 
cooled at the bottom on a cold plate, 12 cells in a module) though VW tends to 
use 3 parallel so a module is typically 4s3p (14V), but this seller may have 
rewired such modules, I don’t know. VW is using 2 different manufacturers. As 
far as I know, Johnson Controls is a reseller, not a battery manufacturer.

Also  the warnings are for lead acid not Li ion.

That eBay pack  - there in the title it says 90vdc, then in the spec it
says 45vdc. That would worry me is that the seller may not be up to speed.
Also, the provenance is very important. Charge level and temperature
history are of paramount importance.  I think the price is nice - if they
are healthy.
