Soooo... I have a 3yr old who will be 4 this spring. I took him to an MX practice last fall, and he loved it. I was thinking he is ready for a gas bike, but he doesnt really fit any of them yet, but i have his 12.5 turned all of the way up, and i think he is ready for some more HP. I was thinking it might be handy to get 2 9AH milwaukee 18v drill batteries. And set his 12.5 up for 36v. Am i Crazy? I thought the drill batteries would maybe be more durable, and the charging seemed simpler. Would the kelly controller work with these batteries? Would i get a bunch more power and speed kicking the 12.5 up to 36v? Ryan
