Does the Cellink Battery B 2nd Gen offer BOTH "BATT" (always on) and ACC (ignition-switched) outputs to support parking mode? Or does it only offer one always on output and require that the dash cam be connected to both the Cellink and the vehicle ACC? I've been trying to find a manual or wiring diagram with no luck. The unit appears to be aimed at this application, but I can't find specific information about how it switches. I have a hardwired Thinkware dash cam, but with all the built-in gadgetry that came with my Ford Escape, I want to minimize the impact on the my vehicle battery.
