@ Chris, I did not have a DMM on at the time, but I checked immediately after it failed to start and was getting a reading of 6.2volts off the battery pack. It worked of the battery pack all day yesterday as I was testing OTA updating and usage tracking features. I disconnected it from the battery overnight and this all happened this morning when I was setting up for further testing.
@ Mtstarr The battery pack is measuring just a touch over 6.2 volts. I don’t remember exactly, but can check tomorrow. It would make sense if it was a typo and 6 volts was the rated max. 6.2 would probably be enough to overdrive it and cause a premature failure. That may explain why it worked yesterday.
