lets see. i was one of the first pano x2 owners (when did that come out?)
that unit has ran 24/7 everyday since i installed it.
vehicle battery will indeed be taxed. i have an odyssey battery (best in the USA) and use two jump boxes.
the jump box uses a cord from company SOLAR that has a obd port on one end and a cigar port on the other. i connect this to the jump box and obd port when the vehicle is off. the jump box supplies power to the system through the obd port which keeps the battery topped off.
i have used the same sandisk 128gb cards that everyone (even the dev of the pano x2) have bashed as not being quality, etc since day one and i have not had any issues with this system.
one thing i have changed over this time was to shut off the screen when the vehicle is parked. screen on consumes a lot of battery power.
but other that that, this unit runs 24/7. i have 64gb sandisk cards i swap out to view footage on the 128s so recording time is not interrupted.
i can say the pano x2 has been solid and a quality unit. i look forward to the next version...
this is my experience. as usual YMMV...
