I made this toolbox for my DJI Phantom backpack bag case, it includes a dedicated place for RC batteries, Allen key and a magnet to hold the motor tightening tool and lots more space for screws and parts. Toolbox size fits Pv2+ battery pockets. A latch holds the toolbox firmly closed and makes it easy to open/close.
