I've owned three Phantoms so far. This Phantom 2 has the 5300mah battery, self tightening props (In the garbage), duel RX antennas w 2.4 TX. I added a TS832 600mw 5.8 video TX, two axis gimbal, all new bearings, 5v voltage regulator (Power for the gopro), and a 900mah accessory battery. All added electrical accessories are totally separate (with the exception of the pitch control cable) from the main battery. Here's a linc to the props I use. keep in mind, they will need to be balanced:
