I believe you will need a set of these Great Planes Charge Lead Banana Plugs http://www2.towerhobbies.com/cgi-bin...&I=LXNCU4&P=ML
And that they plug into the output ports of your charger while the banana plugs/alligator clips coming out of the charger itself must go to the battery that powers the charger (usually a 12v battery). Then the male deans plug goes into the female deans plug on the battery.
