It sounds like he wants to run a seperate, smaller 2s pack just for the BEC, but use a regulator of some kind because the voltage can be as high as 8.4v fresh.

Really, if using a switching regulator, you could use higher voltage (up to 6s). But as you go up on voltage, you don't need near as much capacity. 6s @ 333mA is the same as 2s @ 1A. The only advantage with using just 2s is that if the BEC fails, at least it will only send ~7.4v to the servos/rx and they might survive that.
