I finished testing all 30 of the used A123 cells. They were all about 2.18ah with a 35 amp load. I’ll retest a few of the cells at 10 amps to see how much of a cut Peukert is taking. The fan was helpful in cooling the cells down. As the cells warmed up the voltage would noticeably rise on each cell.

Here is the A123 cell charging fixture without any cells loaded.

Here is how I was discharging each A123 cell at 35 amps. That blue plastic clamp made this mundane testing go by more quickly.
