Oh I know. That's why I had said any donated packs may not survive the testing. It would just be nice to define a set of criteria (like v under load, duration, temp, duty cycle, etc) and then see what kind of C rates the pack can really deliver under those criteria.

I think we can all agree that constant discharging at anything approaching 30C is not representative of 99% of car users. At best, we can usually assume that higher C rate batteries will maintain a higher voltage under a given load, which is better for cell longevity.
