Popped out shopping today and thought I would charge my new cellink b battery pack in preparation for my dash cam install next week. It will be hardwire into the fuse box. I plugged it in to the 12v port and to my surprise whenever stop start kicked in the battery pack would beep as if it has lost connection. The 12v socket is live all the time and doesn't turn off in my car so Why does the battery pack think it has? Is it because the 12v charged drops in voltage when the car stops?
