The G4 is best for charging multiple small battery applications from 2.2-40Ah, such as motorcycles, ATVs, jet skis or snowmobiles. In addition to charging, the G4 can effectively maintain any 6V or 12V batteries in larger applications, such as cars, RVs, boats and trucks. With 4 independent battery banks, the G4 is the best way to keep all of your vehicles maintained at the same time.
