If you plan on running all of your aux. items in this manner, I'd suggest installing a designated deep cell battery for all of your aux. needs.

My brother has this set up and runs everything, except his starter off of it...radio, air system, work/camp lights, cb, charging units for cell phone and computer, etc. He wired it up with one of the Painless systems, so the charging is done correctly when needed. It's performed flawlessly.

Good Luck
