I think by the voltage being regulated down to almost half would effectively increase the mah available. I'm sure the method/efficiency of regulation would be a factor.
Something I alluded to above...
Analog BEC throw away energy as heat, but a switching BEC may do as you said.
I do disagree with Ken on the complexity issue...
Modelers have no qualms about throwing in relatively complex circutry, receivers, power boxes, etc. into their planes all the time.
Why then single out the lowly BEC as a point of faiilure when there are so many other things ready to do that task?
I've had more failures with dying cells, bad switches, etc. than I've ever had with a BEC... currently ZERO BEC failures, even with the cheapies.
