I just bought this for my 3.5ish year old daughter and it'll be arriving a little before Christmas. I know I'll eventually want to upgrade the battery and add rubber to the tires, which probably means I'll need to upgrade the motors to handle the extra resistance. What battery did you end up getting and how did it work?
