DJI FPV Goggle battery mod

Are you sick of these little dji fpv batteries sitting around collecting dust while you use a random 4s pack to power your DJI FPV goggle V1/2.

Well here is a nice little case which you can print to add an addition 4 18650 cells into to extend the usage time of the FPV battery by 3x.

You have to split the case and cut one of the ends off, and then just solder some cable to some cells in parallel to the original cells and stick it into the new case.

I have edited the part so there is no seem between the cases now as well.
