I race IOM boats and with the RMG winch I only use one single battery pack to power the Rx and the winch.

I typically use 6 cell NIMH LD 800 or 850 mah which gives me plenty of power with 7.2v to the winch and then the wnich regulates the voltage to 6v to power the Rx and rudder servo. The 800 or 850 mah is enough to power my IOM for up to 4 hours depending on wind, water condition and rig used.

I assemble the pack myself - I buy them in bulk or 20/30 and then I match them to assemble them by pack of either 5c for 6v or 6c for 7.2v. Pretty much all the RC sailors in Ireland now use my battery pack so they're light and go the distance.

Let me nkow if you want more info...

Enjoy
