What's with all the concern over factory batteries? Even if Yuneec stops making theirs, there's still the aftermarket batteries like the Ultra X. My used TH came to me with one, and I bought another, brand new, at a considerable discount from the factory version. I have no idea of the used ones history, but it's working just fine, even in the cold I'm getting ~15 minutes flight time with the camera running, as long as I'm conservative on the sticks, and that's landing before any alerts. As I'm still getting familiar with the H, I haven't even charged the new battery yet, it's been too cold for more than one flight at a time, anyway. Later.
