NeuEnergy 6s pack wiring

[FG101C]

Calling the RCM guru's for a little assistance.

Just got in the mail my NeuEnergy 6s pack. I feel like a NeuB because I have never seen this configuration before.

So my questions are how do I wire it? I'm guessing it's two 3s packs wrapped as one, but nothing is marked on the wires or battery. If you notice the balance taps one has an extra empty slot, two leads are shorter than the other two.

So do I put the two short leads on one Deans, and the two long leads on another? Then what balance tap is for which deans. I have a Hyperion I610 Duo so charging in Sync mode is not a problem. I'm also assuming the ESC gets wired for series?

Please help, thanks.
