Since you don't state what type batteries you mention using I can't really answer your question. If you're talking about LI Po's don't think you would want 6 in series. Also don't think I would buy a ESC without the Bec why would you want to add more weight? I would try it first with 3, 2200 Ma Li po's and see how it goes you can always add more bat. What is the weight of plane? For charger tha one I would recommend is the FMA 10 S. If you're going to electric go with one of the best chargers.
