Do you not want to "add a fuse" it to the pax footwell fuse panel? That's an option if you haven't already considered it. Most dashcams also will auto shutoff at a set voltage to hopefully prevent any dead batteries.I am looking for a place to hide a battery for my dash cam. Is there room behind the dash, or behind one of the rear side wheelwell covers? Stupid question because I originally thought I would fit it under the passenger seat, but I can't find any room there. Dimensions are 6.10 x 8.46 x 1.38 in, but I would also need to have room to run wiring to it. TIA!
