Not alone, for sure. Many threads about this here and on different forums/sites.
I'm going for a slightly different install though --- I just installed the Zendure X6 battery pack and it works fine so far for running the camera, however the Viofo hardware kit does not charge the X6. So I'll be looking for a solution to that. I was hoping to use the Viofo kit to also have voltage cutoff built in for the battery packing charging to not drain the car battery.
