But, this doesn't work since at lower voltages and faster motors, the efficiency goes down and and you would get less runtime than the higher voltage/lower mah setup.

What I meant by my previous post is:
I bought two of the 2s2p packs, which are each 7.4V 6400 mAh 20C (128A) packs. Wired in series, that's 14.8V 6400 mAh 20C (128A). Wired in parallel, that's 7.4V 12800 mAh 20C (256A). Of course, the amp numbers ignore the whole point of this post, which is the 60 amp limit described in the manual. At this point, we can say 60 amps in series, 120 amps in parallel, until I hear otherwise from FMA.
If I could keep ESC and motor temps safe for the entire 12800 mAh AND keep the vehicle (1/8th buggy or MGT) moving about 30 MPH for the entire 12800 mAh, I'd be one happy guy. So far my experience tells me that I won't find an ESC and motor combo that can run on 7.4V, push out that kind of speed, and stay in safe temp range for more than about 10-15 min. In a 1/10th touring car, buggy, or stadium truck - maybe - but in a MT or 1/8th buggy?
Please, someone prove me wrong :)
