Flightpower Balancer problem

I just got my Flightpower balancer and it includes the connection cables for a 2s, 3s, and 6s, well I am planning on running 5s, I have looked all over the net for a company that sells them, including the Flightpower web site, and have found none. If there are any companies that do sell the 5s connector a link would be great.

Does anybody have any expierence with the Flightpower Balancer, and also on the right side of the balancer there is a pos and neg lead coming out of the balancer next to where the balancer port is...What is this for?
