Cold?  What's that?  Oh yeah, I have dim memory of that sensation.

I was going to put up a flight with my 62" Osiris for a club airshow, I advanced the throttle to take off, the plane accelerated, then the motor quit.  The Castle Controller was emitting two beeps, indicating a low voltage error.  One of the club members had a meter that measures individual cell voltages and everything looked OK.  I used another pack to put up a flight with no issues.
