i have a question if any of you can answer it for me id be gratefull… 
the viair 495c compressor draws 35amps from your battery right? well the battery on my “car” is a 580amp battery, what i would like to know is will my battery be ok for this compressor? and when it cuts in at night will the lights go dim on my car? i think the alternator on my car pushes out somewhere between 55 - 70 amps.
will that be ok?
many thanks in advance 
The air compressor only runs for certain periods at a time. At that particular units CFM flow, it won’t be running long.
Unless you have another electrical modification, like a large stereo system, there should not be a problem.
Should be fine. It’ll only run for a couple minutes at a time, so your battery should be alright. Of course you could run a second battery in parallel if you’re concerned and it’ll insure your pump gets the best current possible.
