TBH: I wouldn't want to hook any UBEC to only one pack because then that pack will drain slightly faster and the dual packs will take longer to balance out when charging. If HV is what you want, then a HV UBEC or a receiver pack would be the best option IMO.

I was thinking about it a bit more and thought a 12s configuration would typically be used in a large heli or plane. Both of these have lots of servos and especially in the heli get worked really hard. So you would be sucking a lot extra out of that one pack. Then I realised you wouldn't be using the CC Bec in a large heli as it would explode. It's only rated to 10A and one big digital servo can suck more then half of that at full load.
