P3A and P3P batteries are identical, the only difference is the charger.Aren't the batteries different too? I have 2 P3Ps and 1 P3A. Don't want to mix the batteries cause of the charger difference (chip inside intelligent battery) but maybe it doesn't make any difference.
I would bet there's more than a few people in this forum that want to sell their p3a due to the degraded wireless bit rate link you get compared to the p3p. The Phantom 3 Advanced just doesn't perform well with 720 goggles like Headplay HD when you install the optional HDMI board. Disappointing. Go with the Pro.There seem to be three more advantages to the pro - 1 . higher preview video bitrate allowing better video with hdmi goggles. 2. Higher bitrate of 1080p video recording - 60mbps vs 40mbps, leading to better video quality.
3. Achieving better 1080 quality by recording 4k videos on the pro , then encoding them down to 1080 in software. I'm still debating myself whether this actually is worth the extra 250 bucks.
