I understand the new Phantom 4 Pro has a new battery that has about 30 minutes of flight time.  They cost $169.  The P4Pro can use the older P4 batteries that have about 28 minutes of flight time and can be bought for almost $100.  You can buy 3 P4 batteries for the same cost of 2 P4Pro batteries.  What do you prefer, longer flight per battery (P4Pro at $169) or buy more batteries (P4 at $100)?
