A123s website is not very informative either but I guess the ones in the dewalts are the ANR26650 cells. The only thing I can find on how to charge them says you need to charge using a Constant current, then constant voltage upto 3.6 Volts per cell starting at 3 Amps, but can be fast charged at 10 Amps. Interesting to note they also said that the low voltage cuttoff is 2V per cell at 25 degrees C and 0.5V below freezing, but this is not what the dewalt chargers do after looking at Johns graphs.

I was just wondering if you charged them like this if you would still get the 1000 cycles life they claim. If so I think it could be done relativly easy but you would really need one charger per cell, maybe a balancer could be used and one charger per pack but we wont really know until someone tries it a 1000 times without any problems.
