Keep in mind that if you do already have some packs that would fit it, that they either need to have the trx hc connector or youd have to modify one or the other plugs. As far as battery packs go though I think anything close to a 6s NiMH pack would work since thats what the traxxas pack looks like. Still think it'd be cool to get one and toss in a CCMS9000 if it would fit, may have to get one of these and try it out.
