I purchased a Blackvue DR900s 2CH after being hit in a parking lot. I'm really looking forward to the parking mode but of course have concerns about the battery drain. I plan on hardwiring with the Power Magic Pro and setting the voltage to 12.5v. From reading, I see the general consensus is that using a USB Li Ion battery is frowned upon based on fire risk due to thermal management. What I want to do is have the dashcam use the power from the car's battery first, and when it reaches the lower voltage limit, switch over to the USB battery. I want to have a cable out so that I can plug in the USB battery as needed. My motivation here is that it uses the safest way to power the camera (car battery) a majority of the time and USB only as needed.
I would only really use this for parking overnight when the temperatures are colder. During the daytime I would not plug in the USB and let it use the car battery. I'll charge the USB battery at my desk or home when its convenient. Is there something that exists that allows this switch?
