I wanted a case for my Vision 40 2s.  I found some for the 1s version but none for the 2s, DJI 04.  This case will fit 4, 2s 550mah Lava batteries.  I also made a simple battery cap to let me know when the battery is full or not.  You can also fit extra screws and the propodile to help pull your props off.  I will probably make another version that makes it easier to pull the used battery caps out of the bottom of the case, for now you will need to use something like a toothpick or tweezers to get them out.
