Hello,
I have a stock B4.1 RTR and was looking to purchase a couple of LiPo packs. Looking at the specs for the ESC it appears I can use either 2 or 3 cell packs. So my question is what should I look at for a nicely balanced pack. I'm looking for something that will give me 6-7 min of run time, but something that is close to but not over that edge for control ability.

What is the big difference between the 2 and 3 cell packs? Aside from the obvious 7.4v to 11.1v. What does that extra voltage actually translate to?
For that matter the (c) rating vs mAh.

Any suggestions would be greatly appreciated (as long as those suggestion won't melt anything except maybe a few tires)

Thanks
