I feel the need to play moron's advocate. What about the ones who do read the bottom of the MMM itself where it says "max input 18 nicad/nimh, 6S lipo"

Now I know better, but if you really don't want the MMM being used with nicads, or lesser nimh packs, why include that info at all? The less experienced user will likely assume that any nicad/nimh cell count up to 18 will suffice. And if they in fact read the manual, they might find some conflict between what is stated in the manual versus the info on the esc. We're at the point now lipos are A. cheap enough and B. pretty well known and used in the hobby. I do think it may be wise to remove any mention of nicad use ANYWHERE in brushless, and have at least stronger warnings about nimh use, if not removing reference entirely to those as well.

Not trying to ruffle feathers, just pointing out....
