until there's an industry standard way to test C rate the manufacturers/relabelers will just throw whatever they want on their packs. Unfortunatly it's the consumer who loses in this.

Soon there will be a way for you to be able to test them yourselves and then decide.

What do mean soon? There is already a way to test them if you feel the need. Get a Castle ICE airplane ESC, put a motor and prop combo on the bench and test away. The castle controller can do data logging so you will have a plot of voltage/watts over time. Comparing these plots will let you know which batteries perform better under load. As for C ratings....advertising gimmick at best since there isn't a standard to test to.

That's it, after 5 minutes in Illustrator I'm jumping in the battery game. Here's my label or how realistic any label is.

Hmm, since most batteries are rated for continuous discharge (except Orion, which appears to be using the burst discharge rate), 7200mAh, 75C = 540A continuous. Too bad the wires and/or solder connections will melt before that rate is maintained. Short runs of 12 awg wire is only rated for a max of 60A.
