Nice. I wouldn't bother with calibration or rounding. Results are relative. Stick with average of 0.57A.

Cut off should have been 163V

7 hours @ 0.57A = 4.0Ah - more along the lines of what I would expect.

Also very useful to document time to 1V/cell (204V) for a more realistic capacity calculation and comparison between cycles.

 

I didn't catch it at exactly 204v, but more than 5, less than 5.5 hours, little more than 3 Ah. it will be interesting to see the outcome, probably in a few weeks.
thanks for help

 

If it responds well, you should get most of the 1Ah between 204V and 163V back above 204V
