C rating is the constant discharge rate... ok heres how ill explain it the higher the C rating the better...
ok so you have 2 200lb men... one is 90% muscle and is in shape and the other is 30% muscle and in not so good of shape...
So when you nail that throttle and things get going though which one do you want going for you? of course the one with the higher C rating is takin it and beggin for more on the other hand the not so in good of shape guy is saying lets slow down and taking it easy...
I'd take these batteries my self.... I'm going to be running them in my 8T soon...
