More deep discharging.
initial poor condition of the pack after ful charging in the car with MIMA

A long time MIMA user got T boned, and the car sat in the shop for a couple of weeks.
He had disconnected MIMA for the past year as His wife was driving the car, and did not want to deal with it.
The IMA was misbehaving and he had some codes and virtually no assist or regen.
He reconnected MIMA,and did aggressive charging (pack Whack) on the way down.
I started by doing a deep discharge to 75V see where the pack was at.As the graph clealy shows, many of the cells dropped out as we got into the final stages of discharge,
