You should use the lion setting cause it "peaks" at 4.1v per cell which woudl be better in case you don't stop it manually.

I think ou only need to set the # of cells... and charge current.

A couple things you can do with the settings....

1. when the pack is dumped all the way, you could try setting the max charge capacity to 100% or a little under that, to get it to cutoff the the charge before it gets to the 4+volts that the lion/lipo profile is looking for. This won't be an exact thing, but you might be able to get it close by playing with this setting.
2. you could set the capacity of the pack higher (like 4600mah) so the charger will allow a higher charge rate. The A123s can take it so why not? If you charge at 2-3c then it won't take long... so you could hang around to monitor it and stop the charge when you want.

If you do bump up the capacity like that, make sure you compensate for it by reducing the max charge capacity. Fro example... 45-50% if you set it to 4600mah(2x) .... about 30% if you set it at 6900mah (3x)

This way you can fast charge it but still have a failsafe of sorts...

For lithiums, there isn't a peak sensitivity...
