That would be expected, as the c rating goes up the batteries get better, especially if these packs were all from the same manufacturer. My point is that c rating from manufacturer to manufacturer is bogus as is anything over 40c. I have some 5000 40c packs that test better than another companies 6600 65c.

That's the sign of a weak cell in the pack. Time to look for some new batteries.

Doubtful. 3 new lipos just don't do that. When I mean new I mean first pack

Do you know what the C rating is and how to test it? Just curious as to how you draw your conclusions.

I've had several conversations with Danny @ SMC and have read thru his posted articles on battery testing. We also use a GFX charger to test packs and are currently seeing very similar data to what Danny has posted.

I used a 25C battery in my SCTE. It didn't last at all. Similar experience. Upgraded to a 50C and 65C, problem solved.
