Yep no problem at all. Take a look over at Hobby Lobby they make a slick system for hooking up multiple parallel and/or series connections.

Of course they are out of stock [] But you get the idea, all you do is solder your esc to one of the sets of holes on the board, and simply plug in your packs and you are good to go.

I used them in one of my P-38s, used EIGHT 3S3700 packs, 4 to a side, wired in parallel and series connections to give me 6S2P7400 on each side.
