Exzes lipo charging

[maineyak]

Hi Guys,
I’ve just purchased a 2s lipo for Exzes X but am a bit confused on how to balance charge it. I asked the SMD if they could help but they replied that they couldn’t because they do not sell my type of charger - which is a Orion IQ605.
The Lipo has 3 leads coming from it which are from left to right (see attachment)
1) Unknown lead (perhaps a different type of balance connector?)
2) Futaba style radio plug (I know this type fits into the rear of the transmitter ok)
3) JST-XH balance connector.

I’m assuming I need to make up a female Futaba lead and connect that to the output of the charger and plug the JST lead into the 2S balance port of the charger too. But is something missing? Don’t I need another lead coming from the 1S?

Another thing that confuses me is that there is a sticker on the JST lead that reads ‘Charge Port’ when I would have expected that to say ‘Balance Port’
Any help would be appreciated.
Mark.
