Default Discharge Rate Compensation?

Is there a general rule of thumb for estimating how a cell will perform at higher discharge rates? For example I've seen a few old matched GP packs that I'm considering for practice packs. The labels state they are rated for 1.25v @ 20A. Any idea what the same cells would do at 30A or 35A?

I realize there is no way this can be 100% accurately calculated. I'm just curious if there is a way to get a rough estimate.

Thanks.
Dave

1.25 @20A is about 1.15 @30A IIRC but really the question is what kind of shape the batteries are in.

Hey Dave what's up... I just noticed it was you.

I think you need to run them back to back to see which feels better... or borrow a Turbo30 and see what it tells you.

Hey what's up Dustin?

Do you know anyone with a turbo 30? The best I would be able to do is test them with a Trinity DPD I have on the way.
