You can charge on a lithium profile as normal.. but the voltage cutoff is higher than the recomended 3.6/cell for the a123s.

So you could just keep an eye on the pack and pull it when it hits 3.6-3.8 per cell....

An interesting thing I see on the mfg spec sheet is that the voltage per cell goes up at lower temps. At 0*C it lists 4.2v per cell charge... soooo if you put the pack in the refridgerator :) you can charge away on a lipo profile and be within mfg specs.

for what it's worth a lot of guys have charged these cells to 4.2 because they don't have proper chargers and it does no apparent harm... but they say it will reduce the life of the cell.
