I'm about to use these packs now, so I'd like to capacity check them first. When I attempt this, I end up with a ridiculously low capacity of 75 mAH or something like that. 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?
