Default What C Rating Do Most People Run?

Well I am not sure if my Venom 5000mah 2S can be repaired...one of the balance wires (red) ripped out from the hard case. That means I would have to dremel out the green case and resolder I guess. I already ordered another 5000mah 2S lipo from HobbyKing (Turnigy 25C) which is a little better than the Venom at 20C.

Looking at our club members most people are running 30C. We are running 17.5 spec class.

Thanks!

I admire you Americans, not too crazy about getting latest equipment. We crazy asians are always getting the latest stuff. I am using 45C cells, and i have lost count the number of times i have been asked by other crazy asians "Why didnt you get 60C ??" It seems everyone over here are using 50C,55C and 60C..

25C should be fine for what you are doing. I'd call what you got pretty decent.

I went from 28C SMC 5000 packs to Venom 40C 5000 packs and was very happy. The 40C packs have more punch and have higher volts at the end of a run.

Sunday I ran in an RCGT race with borrowed equipment. First heat and main I ran a 50c pack. Second heat I ran a 25c pack. It was just as fast as the 50c.

Haha, but of course the cold temps may have something to do with it. I have heard that low c packs can warm up while running more than a high c pack so that may help them out in cold weather races.

A motor will only draw the current it needs. If a motor needs 80A and the battery can only provide 60A, then going to an 80A battery will provide more power. However going from there to a 120A battery would provide no increase in power, as the motor won't use the extra current the battery could supply.

Thats why some people see a difference when they go for a bigger C rating, and others dont. It all depends on what your motor needs (which in turn depends on the class, gearing, ESC settings and driving style).

For my 10.5TC I tried going from 40C to 60C and saw no difference in power. The data logger shows I never pull more than 70A, which the 40C packs are more than capable of providing.

I have run everything from 25C to 65C in my TC (13.5 boosted/17.5 blinky). I've found that higher C rating batteries provide a little more punch for the first 2 minutes or so. It's an advantage in non-boosted classes but not so much with boost. Also, higher C lipos tend to be a little heavier, makes it easier to balance the car. JMO

Don't notice any difference in SC or 13.5 Pro10. My favourite packs are 4000MAh 35C's in my Pro10. Others are using 6000 50C's, and there is no power advantage visible. Unbless your serious mod, i'd say 95% of people will never notice less Cap or C

I totally agree, I talk to a few guys at the track and they can tell you the difference. For a weekend warrior or even a basher, no way. I would like to see experimental "telemetry" data to prove this.

This is the money answer right here. RCGT power demands are not high enough most of the time to reveal the advantages of a higher C rated pack. Unless you are running mod you really dont need it.

Unfortunately many think that they do
I recon its all in their heads, power of suggestion is pretty strong.
When you get guys running silvercan or 23T INSISTING they notice a difference with 50c , then
