If you want to use an audio jack as a bus bar I made 2 3d printed parts for that. I also made a plug support to relieve stress off of the control board wire plugs. This could easily be modified to make a full enclosure if you wanted to, however I didn’t see the need for the extra weight. The plug support still allows for battery tie downs in the form of nylon straps.
I ordered extra tall audio jacks but ended up not needing the height so I hacksawed the top off. I only used epoxy on the bottom holder. Gold filament was just the test fit, I recommend not using anything with sparkles that are possibly metallic and will conduct electricity.

3ds max file link for all the files and a couple gopro mount options. One for walking sticks and another for helmet mount
It took 2 days of trial and error to design the plug support.
