Charging trakpowers

I can charge my trakpower batteries when i hook them up straight to my mrc 989 charger, but when I try to charge them through the trakpower v-balancer, the charger will not recognize the pack. The v-balancer recognizes the cells of the battery when I hook up everything together, but the mrc 989 just shows a voltage of 0.0, like there's nothing there. I have tried it with the trakpower specific plugs and the "normal" connectors (look same) that come out of the same end of the balancer, no matter how I hook it up, if I use the balancer in line with the battery and charger the mrc 989 will not recognize the pack. Any suggestions?
