I know nobody believes manufacturer's claimed C-ratings (especially I guess when they soar to around 65C, 70C), but I figured it was still relative - a 70C pack (whatever the true C value) was still better than a 50C pack. But from what I'm getting in the last few posts, looks like 30C, maybe 35C is about the max no matter what. Begs the question (been asked before), is a manufacturer that claims 30C any more truthful than one that claims 50C or 65C?
I guess only the ESR knows.
Hmm, maybe I shouldn't bother with 65C packs and start flying 45C or 30C packs (provided the ESR is lower).
