Why are you cycling your a123 packs? I have not recycled mine since I bought them. I understood cycling was only needed with Nicad batteries. I have not had problems with pack going down. Perhaps you are killing them or maybe they are not genuine a123 packs. When charging the cellpro chargers are the best for a123. They tell you what is left in the pack before you charge. Charging starts at 4 amps and reduces as it peaks. Charging and balancing only takes a few minutes.
