The key point in this whole discussion is to determine when/why do we get that critical low voltage error. I noticed that it wasn't an issue for me till after 20+ charges and no deep discharge, before I flew often without a full charge no problem. Recently flying with a battery that wasn't fully loaded and at least once after auto discharge had brought it back down to 70% caused the error. Really interested if others, and clearly there are quite a few, have similar usage patterns and reslting errors or maybe on the contrary same pattern but no issues.
