LiFePo4 cells are 3.3V nominal. Your 6S LiFePo4 will be a 19.8V pack (nominal). That's the voltage you should be using when figuring head speeds, selecting pinions & motor kVs, etc. I wouldn't match it with a motor spec'd at 18.5V max., others might though.

Guys have used A123 batteries on the Swift, which are LiFePo4 chemistry, but they had to innovate and come up with custom ways to mount them as they are/were (?) larger than 3.7V Lipo cells. The NX may have more mounting options as it has a larger canopy. Not sure what the largest battery size is though ...
