if im right the little charge lead has 3 wires,two red and one black,the red outer and black outer will go to the cells and the middle red will be the ballance one,i would say you can use the main wires with the red plugs on to be the main charge leads then put the thin ballance lead if it will fit in the middle red hole on the white plug.........DONT DO THIS UNTIL THIS HAS BEEN CONFERMED BY SOME ONE WHO CAN SAY FOR DEFO
