You are right, about the Phantom 2 *Vision*, and it comes with the proprietary battery connection (I am not a fan of the unnecessarily complex and proprietary DJI battery plug system).
I have the less expensive Phantom 2 (non-Vision), and it comes with just the standard 2-pin plug, and it is much easier to find extra batteries for it. I've got a GoPro for post-flight video, and am looking into adding on a FPV system with goggles next, as an alternative to getting the FPV Vision system out of box. Eventually want to migrate the add-ons to a 250mm racer type.
