Received the batteries last week, the poron yesterday, and built a temporary testing fixture to avoid bulging. Popped the chargers on two of the cells and was pleasantly surprised when they both completed their charging sequence at the same time with nearly the same AH.
I may end up building an 8 cell harness and testing the remainder of these cells 8 at a time if the discharge test shows these are all that well matched.
32 of these used (EV pack, Michael) 271AH CATL cells will be added to my current system:
Growatt off grid 6k (SPF 6000T DVM)
Solar city 6k grid tie (delta H6)
64 thunder sky 60AH cells (circa 2008, about 60% capacity)
diyBMS(monitoring and passive balancing only, no control or coms yet)
25 REC 315 panels(7 on solar city, 18 on growatt, half on roof, half not mounted, just laying against the outbuilding)
