RE: Easy start, 12 volt?
No, it will fry the electronics in the wand and possibly the motor. If his battery is dying too soon then get a different battery with a higher mAh rating. A 3000mAh battery will last roughly twice as long as a 1500mAh one. Also, be sure that his charger is fully charging the battery. Some of the chargers that came with Traxxas vehicles tended to under charge batteries.
