I think Julius mentioned here earlier in the 705 thread that Rene and sometimes himself used 4 cells (4.8V) for the receiver pack. We asked him if it was any difference in performance of the servos and he said he did not feel anything lacking.
I think if you're using controllers like Futaba 3PK or equivalent or external fail safe, you cannot use the 4 cells because the controller may lock when it detects the receiver pack to be less than 4.8 V. Unless of course you switch the battery fail safe feature off...
Anyway, Julius also added that the lower the voltage of the receiver pack, the lower the current draw.
Rene, how long can a 4.8 V receiver pack last in the car? Using both digital servos for throttle and steering?
