Thanks for the replies guys. I guess I was thinking the specific flap battery would be beneficial, since I have some other battery needs other than just the primary surfaces. Such a a lineal actuator on the canopy, landing lights, and I will add cowl flap operation down the road.

Yes Invert, that makes a lot of sense and is a great idea. BTW, this is for my TA 152, I am getting closer to being finished now.
