When I recharge the packs, that is approximately the same amount being put back in. I assume I'm not discharging them properly, and probably ending prematurely. What is the per cell cutoff voltage that is appropriate to these A123 batteries?

Anything else I might be missing?

Thanks,

John
I apologize in advance if this sounds insulting (not meant to be) but you ARE using a charger that has a LiFE setting on it, right??
