I bought some grade A EVE LF280K cells from Jenny and when I tested two of those cells I found their capacity around 270Ah, these are brand new never been installed and I am told they are grade A and they also look like it. Is this normal? I was expecting them to atleast be 280Ah if not exceed their rating.
Testing was done using Junsi 4010DUO @ 25A in 3 steps, 1) Full charge to 3.6v, 2) Full discharge to 2.5v and then finally 3) Full charge to 3.6v.
Both the cells I tested fared around 270Ah.
I also used this method to test few of my other grade b cells bought from AliExpress (scam) from last year and most of them tested over 280Ah, some of them going over 300Ah too. Not sure if I am doing something wrong here.
I can see many videos online but has anyone here on the forum tested it like I am doing.
