A large empty instant coffee container, painted brown, with a hole drilled in the bottom should adequately protect a V2 camera and a power bank. The intention was to use a spare V2 outdoors in the weeds to capture video of critters overnight. A 10,000 mAh power bank lasts overnight easily when only capturing events. I think the power bank will last about 8 hours during constant video capture. I did have to use forceps to attach the micro USB cable to the camera due to the orientation in which I had to squeeze the camera through the regular opening.
I may also find a covert mission or two where video would be useful.
