New Duratrax Evader BX electric buggy

Got a free DURATRAX EVADER BX electric buggy today. Gonna keep it for parts, and use the battery and charger, so thats 2 chargers we will be using at the races, and 3 batteries. Will need to get another 7.2v 3000 battery so the buggy and the truck can complete the main races, the 7.2v 1500 battery will make it for qualifying, but they wont do the main race.
