DJI's authorized my Amazon.com seller, Kellards, to refund my purchase for a Phantom 2 Vision that has the "invalid Battery" problem that persisted even after doing the requested software & firmware updates last month that would supposedly fix the problem. I'd love advice on what to replace it with: another Phantom 2 Vision or a Phantom 2, with the Zenmuse gimball and the GoPro Hero 3. Does anyone know if the invalid battery problem has been eradicated from currently shipping Phantom 2 & Phantom 2 Visions? Many thanks in advance of your input!
