Pack Testing Factors
In this test while fast charging without fully topping off the cells, small imbalances become magnified meaning that there is some capacity that becomes unusable.
This doesn't stop the pack from delivering a fairly constant capacity after some threshold of imbalance is reached.
Knowing this I decided to terminate the charge cycle a bit conservatively which also reduced time of each cycle substantially to a mere 45 minutes including charge and discharge.
However I wanted to fully balance the cells every 50 cycles and see what their full capacity would be if I slow charged them to full.
On cycle 51, 101, and 151 I fully slow charged them and made sure all cells were +/- 0.01v in balance. (with a trend of the cells moving towards a more similar capacity as cycles progress, requiring less manual balancing at cycle 151 vs previous)
