Need some battery help :)

[rawfuls]

Holy bajeebus!
That's an expensive battery!

If you still have the old battery, and there's still some charge, I'd say just measure all the voltages across every wire, or hell, even open it up (carefully), and see what's connected to what.
Using that, draw a picture, unsolder the connectors, and hook em up to your new battery..

Or..why not just resolder the PCB (4in1, assuming you have one, or RX or whatever) to match a regular JST plug?

JST's are reasonable for 2S under 2000mAh, so I've found.

EDIT:
After doing some digging around on the web, found this thread:

Looks it's practically the same as the balance connector, black is negative, red is positive.
So if you connect w/o balance, see if it'll work?
