putting on own balancer connector

I was thinking of swapping out new batteries balancers connector plug to align style, so it will be easier to charge all my batteries. I'm doing this to 2s lipos, so there will only be 3 wires. The only problem is i don't know where does the wire go. which terminal and all that. An example are these batteries.
