Li-Po or NiMH? I'm confused.

52.8 amps continuos rating should be fine as long you aren't geared to the moon or bound up. You most likely wouldn't have any trouble running a 6s on the warrior with the right motor, but it will technically void the warranty. I have doen it myself without problems, but if the controller failed, I was willing to accept it as a learning experience and move on. If you are willing to do this as well, I would unofficially say the warrior can handle the 6s. My personal recommendation would be to run 5s Lipo and stay within the posted limits of the controller.
