50C Lipo = Better for MOD Racing
40C Lipo = Better For High Turn Motor

13.5, 17.5, 21.5 = All this motor is not capable of pulling high AMP continously so there is no point on getting a high C rating batteries if you are just running high turn brushless motor.

In stock 1/12 there's been no difference in lap times at all going between 40c and 50C. The motors just aren't pulling more than 200 Amps

Granted this is 2nd hand info, but my friend swapped from a red case smc, to a new 50c thunderpower in 1s 13.5 and said it was a night and day difference.

There's no need to switch to 50c batteries for stock or superstock - 40C is more than adequate.

The difference people are seeing between different C ratings has nothing to do with coming close to the amp draw capacity of the pack. A higher C rating will allow the pack to maintain its voltage under load. Whatever that load may be, a pack with a higher C rating "should" be able to maintain a higher voltage.

Now of course, this difference may be very small. Maybe so small that not even a pro will feel the difference. But trust me, the pro's are labeling packs with average discharge voltage and internal resistance and using the best packs for big races. Don't forget, this is racing. The idea that you may have left anything in the pits is not the goal.

And even if you are racing mod, which I do, you don't need any more power!

I have no real data to support this but; I would suspect that tha small power gain of the 50c would be negated by its slightly higher weight. So all in all I would guess that there is little or no difference in the 13.5+ motors, mod if you need more power you just motor up as allways.

The new speedo's are one of the reasons why these batteries are doing well in the stock classes.

Actually not true.

All but 3 drivers in 13.5 17.5 and 17.5 masters were running the advanced speedo.

The speedo facter was the same for everyone.

well, you could go by the advice you so readily hand out all the time in other peoples threads! Go to your local track and ask the people that have been racing a long time instead of posting a stupid question like that here! i have seen you post that response more than a few times before......

I'd guess it actually was the DRIVERS that won the race and not the speedo or battery.
