Did you record (or note) the SOC / Ah as well? If so, what was the observed SOC at 25.35V during this capacity test?

I posted the following in another thread but I wanted you to know I did not forget you and your question.

The voltages on my last test shortly before the BMS cut off were as follows in order of cell number 1-8.

3.010, 2.813, 3.008, 2.973, 2.934, 2.983, 2.625, and 2.848

And the following are some interesting measurements I noted when the cells drifted more than 10mv's.

Amp hours remaining at 25.35 volts = 25.24. Voltage Difference = 0.010 Capacity = 9%

Amp hours remaining at 25.30 volts = 21.25 Voltage Difference = 0.020 Capacity = 8% Cell 7 volts lower than others.

Amp hours remaining at 25.25 volts = 19.72 Voltage Difference = 0.033 Capacity = 7%

Amp hours remaining at 25.20 volts = 17.59 Voltage Difference = 0.057 Capacity = 6%

Amp hours remaining at 25.15 volts = 16.98 Voltage Difference = 0.066 Capacity = 6%

Amp hours remaining at 25.10 volts = 16.10 Voltage Difference = 0.079 Capacity = 6%

Amp hours remaining at 25.00 volts = 14.64 Voltage Difference = 0.102 Capacity = 5%

Amp hours remaining at 24.90 volts = 13.57 Voltage Difference = 0.110 Capacity = 5%

Amp hours remaining at 24.80 volts = 12.71 Voltage Difference = 0.122 Capacity = 5%

Amp hours remaining at 24.70 volts = 11.96 Voltage Difference = 0.132 Capacity = 4%

Amp hours remaining at 24.60 volts = 11.20 Voltage Difference = 0.140 Capacity = 4%

Amp hours remaining at 24.50 volts = 10.58 Voltage Difference = 0.150 Capacity = 4%

As you can see when the pack of the voltage approached 25.30 volts is when the voltage of cell 7 dropped below the other cells.

When the charger cuts off and my cells are full there is only a 0.083 voltage difference between the cells thanks to parallel top balancing.
