I did capacity test on 4 cells to test and found them all in the 308-312 range. I put together a 16s pack of 304a cells. First I top balanced them all to 3.6 together. At the start of testing they were all in the 3.431-3 range. After ~ 100ah discharge I had a low voltage shutoff by BMS. One cell was at 2.5, and two others were at 2.9 and 3.0. I checked and all of the lugs were tight and I verified the voltage using multimeter to make sure it wasn't an issue with a bad connection.
The discharge was at around .25C max during test.
What am I missing besides these 3 cells being lower capacity?
