Fat Shark FPV Goggle Battery Holster / Cable Keeper
This holster fits a small Fat Shark FPV goggle battery and keeps it snug within the head strap. The version with clip also reduces the chance of the barrel shorting on random things in your travel box.
To use: remove the head strap from the battery side, slip this thing over, and reattach. Then drop in the battery and slide this back over to lock it in. No rubber bands or velcro needed, and no discomfort was felt when wearing.
