Which C rating Battery is best for WGT?
 

I am running a CRC x10 with a 10.5 ballistic BL motor and am wondering if I will notice a difference between a 40c and a 50c battery? I see now 65c is out now as well.

I have a 4900 50c and a 5600 60c and the 60 may have a little bit more the first 1ft but after that no difference.

If those 4900 vs 5600 capacities are real, you will have more poop to draw from as you get into similarly timed runs. The higher the capacity, the more the voltage stays up for given period of time.
