Thanks for sharing , great mod.
Is the male plug going to stay secure in that, having gravity and bumps working against it?
Or, just buy the powered SW Motech tank ring and bag.
I thought it'd be sussed, seeing the research you do.
Yep, it’s the Blue Sea Systems plug that “locks” into the socket with a small sideways twist. The plug also has a rubber waterproof seal on it so no water can get in.
