Running air compressor off deep cycle battery

Hey guys, I have a question. I have a Viair 90P air compressor that requires clipping on to the battery. It's for my truck and the hose won't reach my RV tires unless I unhitch. I'm wondering...could I clip on to the deep cycle battery in my 5th wheel and run it? It would be nice if I could do that instead of getting a separate air compressor for the RV tires.

I assume the battery has the juice since I'd only need to run it for a few seconds to top off the air, but I'm wondering if it would cause any sort of damage to the RV systems. Also, if it will work, should I unclip the battery leads first and/or use the battery disconnect switch?

This is the battery that I have in the 5er - http://www.walmart.com/ip/EverStart-Maxx-Group-Size-24-Marine-Battery/20531538

Thanks

    Just hook the compressor up to the battery and compress away. No need to unhook anything from the battery's. Only caution would be it won't take long to run down a battery with this compressor so if you needed anything more then a quick top off you could run the battery down fast. If your truck is wired to charge your trailer battery's when hooked up then plug in your trailer lights and start your truck so the trailer battery won't be sucked dry.


    Thank you! That makes life a heck of a lot easier (and cheaper).
  • Yes, you can connect it to your RV battery. That compressor uses a max 23 amps so running it for 10 mins would use up about 4ah of your battery capacity.
