I just meant you'd have so much runtime with the 12,000mAh batts that you'd get bored with driving the truck around before the batteries died.

As far as the controllers, these are very good units with an adjustable cutoff so you won't damage the LiPo cells...

For the motors, I really like the Fiegao units. Good quality but they don't cost an arm and a leg...

For the batteries, you can get away with the maxamps packs in an E-Maxx because they're pretty enclosed and you don't have to worry so much about damaging them. Plus, they're inexpensive comparitively. The 6000mAh 2s pack would be great but if you really want to go nuts, get the 12,000mAh one. It's the 8th one down on the page...
