@Steve_S,
Please accept my apologies for so aggressively challenging you with regards to voltage "settling" of LFP cells. My experience with rapid settling of 40Ah CALB cells did not translate to the 280Ah Eve cells.
My Eve cells obtained from Amy experienced dramatically lower settling rates.
Cell 1: 3.46 after 5.5 hours (also the lowest capacity, 2.6% lower than the others)
Cell 2: 3.52 after 23 hours
Cell 3: 3.50 after 22.5 hours
Cell 4: 3.53 after almost 4 hours
Cell 5: 3.52 after 22 hours
Cell 6: 3.50 after 22 hours
Cell 7: 3.53 after 4 hours
Cell 8: 3.52 after 3.5 hours
Cell 9: 3.51 after 4 hours
After sitting for almost 4 days, I ran the bolded ones through another 20A to 3.65V charge (already full). They all terminated at 2A within 2-3 minutes. The amount of charge accepted across the 5 varied by 180mAh (.06%).
Here's a plot of one of the settlings:
You were right.
I was wrong.
