After waiting a couple of months, I got my first set of 8 100Ah cells. I charged them and top balanced them. I did a capacity test. How are the testers on Youtube getting 100% of the rating out of the batteries? My batteries top balanced at 3.470 (all within .002). Looking at the charts available here and elsewhere, that's essentially 100% (99%+). Since I was using one of those cheap Chinese testers, I limited my discharge to 5A (@ a nominal 24V, so 100W). and stopped the test at 24V. According to most of the charts, that's about 10% capacity and you shouldn't go below that. So, from 27.76 down to 24V I got 88.8Ah. 100% to 10% = 90%. After the test all cells were within 0.06V. Should I be happy with my 88.8Ah using 90% of the charge or should I do a 100% test? I think I'm happy where I am, I'd rather not destroy any cells. How do you do a 100% test?
