I had the same trouble getting the boys at B.D. to commit to a single output solution on thier stator. If I need a large single output stator I use the Ricky Stator 200w with one of his heavy duty regulator rectifiers. The instructions that come with the stator show you how to connect it for single output and you don't need to add a huge battery. But you do need one of his reg/rect's, the B.D. reg/rect will not handle the power.
