I'm trying to find out how I can charge up a 7.4v 10ah lithium polymer battery from a 12volt cigarette lighter socket I have found a circuit for a 7.4v 800mah lipo charger! Can I change components on this circuit so it will do 10amps? Or does anyone know of a circuit out there that will do the job better? Any help I can get will be muchly appreciated. P.S. I'm will be using the battery for a metal detector and I want to charge it up out in the bush.
