After a bit more searching I believe I answered my own question. Since your lipo only has a balance lead, which I find strange and uncommon, it should plug in directly to the right side of that charger into the 2s balance lead port.
There are tons of standard charge leads available for purchase on Amazon, ebay, amain, horizon, and many others. Charge leads are universal to just about any common charger but are not required for that particular battery.
That all being said, are you familiar at all with lipo batteries? If not, I strongly recommend taking a little time to educate yourself on lipo charging and safety. If done wrong, the results can be disastrous. There are threads on this forum that will more than provide you with the information to use your battery and charger safely. Please take the time to read up on the subject matter before you do any charging. Safety first!
