wiring it all up

I have my 9920 on the way and want to try and understand the wiring of this thing. From the searching Ive done I think I want to wire my batteries in series. Do most wire the Emaxx in series :032: Im using 16 cells with a 9XL.

Is this considered wired in parallel or in series?


This diagram is a little bit different then the one that comes with the External BEC/UBEC, but Im assuming its the way to wire it all together, right :032:
