During my last flight, proximately one hour into the flight, my EarthX warning light started flashing for about 1-2 minutes and then stopped flashing. While this event was happening all my volts/Amps were normal, putting out 14.2 volts and the draw was the normal 19-20 Amp. The EarthX cheat sheet indicates that it is not of a concern and it means the cells were imbalanced and were being charged. Just wondering if others have seen this and if so, how often do you see it happening? Any warning light going off makes me nervous.
