Newbie has questions about a BL setup

I had a look at those batteries akratz, and I don't think they will be up to the job for brushless. You should be able to get a decent set of GP3300 14cells fairly cheaply. One essential thing to rememeber is your motor can't put out more power than your batteries can provide - so if your batts are crap, then it doesn't matter how powerful the motor you stick in the truck is, you still won't get much speed.
