1. Year you have - 2014
2. Any issue with battery dying? - None
3. Any tesla warranty issues? - None
4. Does the big battery charge the small one if it starts to drain? - Yes
I bought the blackvue 650 dual channel system and did the install myself after seeing how my local installers did it. Reason why I chose to do it myself was cause they all seemed to just tuck the wires where they could and leave them exposed on the top of the windshield. While the wire position kept it form being seen by anyone inside the car anyone waling by would see the wires and the sticky clips and I wanted a clean seamless install. I routed the front wires through the top headliner (no pano), and tapped the ODB connector for a constant power source then ran the back wire under the door sill. Once at the back I removed the c-pillar cover and parcel shelf rack and routed the wire up to the lift gate and jumped the gap (only place you can see the wire). Other than that one place in the back there are no wires showing and it looks like it came as part of the car.
