Drop out test needs more work

Drop out test needs more work
Second cycle old insight pack

The second charge of the Insight pack showed increased capacity, and the cells held up longer on the bottom end, but it also showed that our simple drop out detection system was not good enough, so we must change the way we detect the drop out.
The present thinking is that we will look at the rate of change during the linear part of the discharge, and then look for that rate of change to shorten to a percentage of that rate, as a drop out detect, this will allow us to detect the cell(s) as they begin the drop, rather than looking for a specific number on voltage drop / unit of time.
The 30 minute topping detect could also have been longer as the pack still seems to be rising when the charge was terminated
