The LiFe packs have the balancer lead attached, and it connects up with the balancer adapter nicely. That plugs right in to the balance jack on the charger. I have a set of heavy leads (large gauge wire) with deans on one end and banana leads on the other, red to + and black to - to connect to the charger.

I set my charger up for LiFe, 6.6 volts (3.3 per cell, two cells, 6.6 volts nominal), 1.8 amps charge current (1C) and let it go. Worked just fine. Note, 1800 mah packs = 1.8 charge current or 1C. Press and hold the rotating knob until it starts to charge (about 2 seconds) and let it do its thing.
