Thanks, Lyle. The additional question I was asking here is if the 
KXPA100 pull proportionally less current from a 14.8V supply to achieve 
the same output power than from an 11.1V supply?  (The difference is one 
less cell in the Li-Ion pack.) The calculation I'm getting at here is 
for a given pack weight, do 11.1V or 14.8V packs give me the most power 
out per pound?
