Charging at the track

If you wanted you could pickup a jump box, and have it to charge your batteries, and would double around the house if you ever need to give something a jump box. They are nice to have around. A marine battery is just designed to be ran down slowly, and farther than a car battery without damage from doing repeatedly. You can charge off it all day long, and if you run it way down it can be slowly charged back up without damage. As long as you are not killing you car battery should really have a problem with it though. I don't know how many classes you race, I might would just pick up a few more packs so you don't have to do so much charging at the track.

Sounds to me like he is letting the car sit there and idle while he is at the track charging... Thats the only way I can see it costing any gas milage.
