Experience with magnetic qi car charger topic

I'm about to build one but I haven't found any experiences of people with a note 4 in regards to battery temps. Are any of you using this set up in your car? I'm a limo driver so it'll be running bluetooth music, navigation, voice, text, and Gsheets 55 hours a week. A spare battery wouldn't be awful but it would cause a hasty case peeling every day.

I plan to simply tape magnets into a plate charger and my case, tape the plate into an iottie, and connect it to a 3amp connection.

If you are having heat problems please mention your feed amperage and if you've seen any battery capacity changes. I'd pay 20$ every six months to replace it but I don't want a steady decline in capacity.

Coupon for iottie and mpow got me 5$ off each, magnets and tape from leftover projects. 50$ total, plate fits perfectly like it was a phone and tastefully wrapped gorilla tape should make it non slip, well anchored to the iottie, but still easily removable with a knife. Phone then sticks just outside of the claws against the plate. Just waiting and stressing over heat before the qi adapter to arrives tomorrow :)
