Slim 4x 18650 Case / Pack for DJI FPV Goggle

I switched from and HDO to a DJI Digital FPV System Goggle, this one requires a 4S battery. So I came up with this so that I can have a very flat 18650 4S pack in my pants for flying.

The idea is to use this with your DJI FPV Goggles, obviously you can use this for all other projects requiring a 4S 18650 pack as well. I mainly use NCR18650 cells for this use case since no high amperage is required.

For a full pack you will need:

• Printed parts
• 4x 18650 cells
• 4x M3 screws with at least 10mm length
• Power cable
• Balancing cable for 4S pack

Edits:

Oct. 8th 2019: Added a top with more space for the cables.

Oct. 9th 2019: Added images of an actual pack.

Warning / Disclaimer:

Your are doing this on your own responsability, only build this if you know what you are doing. Please be carefull, building such a pack an making errors can result in explosions or fires. Make sure not to hurt any wires during assembly.
