Hello Bud and All,
After many many attempts (just before throwing my hands up in defeat) we finally were able to reproduce this failure. Not only did we get the unit to fail, but once it failed the first time we could reliably reproduce the failure. Brought the unit, in the failed mode, to engineering firmware guru DT and we already have some theories. We will know more early next week and will let you know the results. By the way I was able to reproduce the failure when the battery voltage was above 90%; however the 1st failure occurred at 1.15 volts with some "special" battery connection.
Thanks for the opportunity to look into this (again).
Very best regards,
Dean Slotness
