Just to add to the post.In theory yes, you shoudn't need an external battery to prevent the 12v batter from draining. I've had mine installed in both my wife's Acura and my Taycan for months now without issue. However, I seldom go more than a couple of days without driving/charging the Taycan.
The prior Blackvue models did not have the voltage monitoring. They did sell an optional battery that could be connected.
So if you hardwire the newer model (900 series), in the Blackvue app you sent your voltage limits and if the voltage drops, it turns off the dashcam automatically. This is to prevent draining the 12v battery.
The dashcam is powered by the 12v battery and not the Taycan battery. However, a drained 12v battery would not let you start the car so the voltage monitor is to help prevent that.
