    Why would it go slower? They is sub-C cells just like RC cars do. Btw, the Dewalt 18v XL packs use Sanyo 2400 cells.

    well if you run a seperate battewry and the wheels arent turning then it is either the reciever or servo that isnt working right

    Can you use a seperate Battery? Alot of those Radio Shack Trucks have very intergated electronics. The radio maybe designed to run on 7.2 w/o a bec.

    too much voltage will cause the servos not to work, cus most esc's cant put up enough resistance to that much voltage so the extra power makes it through all the time (which is why your truck goes all the time). in my tmaxx i had a 9.2 volt pack and it did that so i know from experience.
