From what I can tell it will charge them (CC/CV mode) to 3.6v per cell. You can charge at up to 8 amps. The Ice will not let you charge more than 1C
but you can fool the charger by setting the capacity to 8000mah and get the 8 amp maximum that the ICE can give. It wouldn't effect teh peaking of the battery at all. It would be just a little slower than the 10 amps that the A123 charger delivers but still very fast.
I'm asking because I have two ICE chargers and was thinking about getting some of the batteries but don't want or need another charger. I could charge two packs at once with my ICEs.

That 3.6v for Li-Ion is the
nominal voltage. It actually charges to 4.1v/cell, which for the most part is too high of a voltage.
You can use the ICE to charge A123 cells, but you need to stop the charge manually at 3.6v/cell (7.2v for 2s, 10.8 for 3s, 14.4v for 4s, and 18v for 5s). You could even do a manual CV phase of the charge by decreasing the current to keep the pack at 3.6v/cell.
One way to do this automatically would be to get the LiPoDapter:

It will automatically stop the charge when the pack reaches 3.6v/cell.
