The 4mm banana plugs connect to your charger and the small 2mm plugs connect to your battery. You battery needs to have banana jacks for it to work. Appropriate batteries are the CheckPoint, TrackPower, Orion and similar batteries. The MaxAmps batteries won't work; however, the balance cable is removable and you can get cables appropriate for the MaxAmps style balancing port.
I use the Ice charger and the CheckPoint balancer. They are simple to use. Simply make the connections from your charger to the balance charger to the battery. The CheckPoint balancer has a button that allows you to select balance mode or charge thru mode. The balance mode simply discharges the high voltage cell(s) until all the cells are within a voltage threshold. The charge thru mode balances while charging.
