Before buying two more batteries for my Phantom, I had one thought in my mind: ONE and ONLY battery model for Phantom 2, Vision and Vision Plus. But when I received the batteries, I could notice a model difference and a slightly difference between these ones and the two ones that came with my V2 Vision Plus. See the attached image. On the left, there is the model that came with my Phantom (733496-5200mAh-11.1V), and on the right, the model that I've just bought (PH2-5200mAh-11.1V). I've seen some posts saying that this PH2 battery has improved cells and stuff, but they deliver less voltage when full throttle. Do you guys know anything regarding these models, that could help me? Thanks a lot!
