I love this backpack. got it couple of days back.
This is updated model and it accommodates phantom 4 and pro batteries as well.
check out the video I made. Hope its helpful to you guys !
Have you guys seen the new DJI Phantom 4 backpack? Looks pretty slick IMO

I like it better than the P3 version.
