Sorry I really can't answer any of those questions. Those cells came from exploric I was told they were 280 Ah REPT grade a cells. I have some installed at a customer's. But haven't checked them at all since. One thing I did notice is some of the cell had a fairly high internal resistances (not any that ended up in that pack). Which when charging could cause your bms to drain that cell causing a imbalance situation. So bms setting very crucial, and I would also suggest if you order from Alibaba you get a video of them testing internal resistances of all the cells.
