So you can see, it has two levels “kind of”....the large insert lifts out with the nylon handles you can see on the sides if you look close. Top has storage spots for 4 battteries + 1 in the drone, or if you have a MavMount, the one battery slot is laser cut so you can remove part of the foam to accommodate the nave mount, leaving 3+1 battery spots, and I currently only have 3 total in there, and Oswald one of the battery holes for my lanyard. You can see there is a spot also cut under the drone for the iPad mount part of the MavMount. I slide my 3 count PolarPro filters in the empty slot you see on the left. Any questions, just let me know! Hope it helps!
