I just scored a battery and charger on sale at radioshack for $15.00.
I'm not sure if it is better than what was in it, but it's better than nothing. I'm not planning on seriously upgrading this thing unless it fries, so a new radio system will not be in the works. I have no idea what the hell any of you are talking about when you use all those abbreviations, I'm a super newb to rc vehicles and upgrades.
I'm about to tear it apart and lock the rear, wish me luck.
