Flying last night and suddenly my battery warning goes off and the alarm sounds on my iphone. The battery still had 70% charge however. After landing it I tried a low hover and while in the air it kept switching from a stable regular charge to the warning alarm and attempts to auto-land. I managed to grab a screen shot that shows my battery in the "red zone" while still at over 40%. Later that night I connected to the assistant software to verify my battery warning indicator settings, and they are all set to the default settings. And my gimble is having seizures and violently thrashing about but that's another story... Anyone see this type of battery issue before?
