so a 6v 1400 will last as long as a 4.8v 1400?
No that is not what I said.
I said: "that at 6v a single pack ( the one you posted the link to ) will last about as long as a 4.8v 800mAh pack

i would think a 6v 1400 would last a little less than a 4.8v version.
Correct.

but then again those pesky amps screw everything up, does a servo really draw that much more (amps) at 6v?
Yup another reason you want additional capacity, to sustain the additional draw.
The upside is that the higher amp draw tends to occur only in bursts, so while you want to allow for it, the relative impact does not have a linear relationship in the realworld.
