6 cell question

[adamn84]

I was bored this afternoon, so I went out to radio shack and got a battery holder to do the 6 cell mod. After a first attempt disaster, putting my primary car out of commission for a while, I got it installed on my backup car.

My question is can I use the 6 cell with my pnracing motor?

I'm pretty sure it'll be ok but I wanted to be sure, as I'm down to my last car. I don't want to fry the board or overheat the motor or something.
