No, if you order the RC batts and get the box from Leegeddy, you're set. He'll make you the interconnects (usually XRL, correct me if i'm wrong) to go between the box, the batts, and each peice of eqipment you're running. Check out Bean's thread on the VR box, it was one of the first made if i'm not mistaken.
And of course, be sure to drop Marc a line. He'll hook you up for sure!
