They are air-mailing me a new unit. I'm buying a new battery that will be dedicated to this unit.
These HB units have a low voltage protection shutoff feature...

I don't recall ever hearing of issue where this low voltage protection actually damaged internal unit parts..

Something has changed in the new units or freebird just got unlucky more than once...

The x99's are still in their infancy...if a trend of certain issues start popping up for any new model...I'm sure HB will recognise and hopefully find a remedy...
