Don't use the temp cutoff - its terribly inaccurate on the Ice - set it at 120F so it won't shut off early - lipo won't be getting hot anyway. Set discharge volts to 3 - you risk puffing (if you discharge on tehIce for some reason) it taking it below 3. I have run many of Integys 2 and 3S lipos in 18th scale, they will puff going below 3. You shouldn't be discharging anywhere except in the tx anyway.
