What is the differance between the "C" ratings and what do they mean?

There are several ways the 'C' figures into lipos - prob the most important is in figuring current the lipo will deliver. Example if you have a 25C 5000mah lipo, this means it is supposed to be capable of putting out 5000/1000 x 25 = 125amps continuous current. There is another C rating which is the burst rating and its usually only good for 15 - 30seconds. Its higher than the continuous C rating. For the example, that batt may have a 30C rating meaining for short a period, that lipo could put out 150amps - (5000/1000 x 30 = 150amps).

The C is also used in charging as a 1C charge which most lipos are charged at, again, its the lipo mah divided by 1000, again, example - 5000/1000 = 5amp charge.

So the higher the "c" rating the better the battery?

Thats the theory. Problem is that some manufactures or "matchers" are possibly padding the #'s a bit so its a little difficult to know who's tellin the truth. This is the way I've been readin all the hoopla anyway.

^^^^^ Thats correct, higher the C rating, the more amps, the more performance. Unfortunately, there is no industry standard for establishing this rating and some advertise inflated ratings. You can count of the high quality cells (Enerland, Kokam etc) to pretty much deliver what they say they will.

I've been impressed with the way SMC rates their lipos from reading their posts here in these forums - mostly in the electric threads - they do a great job and deliever what they advertise.
