New warning insert in MMM box: "DO THE MATH!"

I think my Hyperion EOS0610 II can measure the resistance of a pack, but maybe that's not the right sort of resistance reading? So, can the way you have your ESC and radio set up for braking help minimize this, or does the ESC respond to any braking the same way, regardless of how hard or light it's set to?

My Flightpower Packs are rated at 25C, and they are 3s 5000mah packs wired in series. Since they are higher quality batteries, I'm assuming that 25C is good. But if they were a cheaper made Lipo, 25C for the cheaper pack won't be as consistent? I guess that's the rub.... 25C isn't always 25C, etc. Right?

The charger can measure IR (Internal Resistance), so thats the figure you want- the lower the better.

Changing the brake strength wont really help much- even when you brake gently there will still be the regenerative braking effect sending current to the lipos, so decent lipos are needed regardless. If that doesnt get ya, the ripple current will...

Your Flightpowers will be fine, but you are kinda right about the cheaper lipos; not so much about the consitancy (10c lipos can be consistant, you just wouldnt use them for a demanding application), more to do with inaccurate/ or exaggerated ratings. A low C lipo cant deliver much current when you start to draw beyond about 15C, the voltage drops like a brick and the temps climb- hence why higher C rates are much more desireable from decent brands.
