If the volts are to low you can try to drop a cell rating and charge them up to above the 12v mark. PUt is on 3s for the 4s cells. Then swap them to 4s to finish them off. I would charge them slow and keep an eye on them.

Or, charge them in NiMH mode at a low current and make sure the charging voltage doesn't get any higher than 4ish volts per cell. Once you get t0 about 4v/cell, you can switch to lipo mode. Like CHC said, you MUST keep an eye on them...
