DJI has a battery sale through 1/7/17 on the P4 "intelligent flight" battery:
http://store.dji.com/product/phantom-4-intelligent-flight-battery
Be aware, however, that while this may fit in a P4P, this is a 5350 mAh battery. The P4P battery is a 5870 mAh battery. That is a 9% difference, and will result in a shorter flight time. YRMD.
While we are on the topic of batteries, also be aware that aside from spinning blades, the battery is the next most dangerous part of your UAV. As someone who started out with a P1 which used plain Li-Po packs (but really cheap!) stored in ammo cans, the advent of "intelligent" packs which prevent overcharge has been very welcome. Spend 10 minutes on YouTube to watch exploding Li-Po battery fires and you will never grumble at the cost of an authentic intelligent battery again.
