I forget the formula for figuring out the c rating. Can some one refresh my memory please?
Thanks Tom

(C Rating) x (Amp Capacity) = Continuous Amps Out
e.g. Elite 3S LiPo rated 30- 50C, 4500mAh
30C x 4500mAh = 135 Amps Continuous
I find that it's not really continuous at 135A beyond 30 seconds. The practical and safe "continuous" rating is 80% of that. In this case 108 Amps.
Not sure if this is the formula you were referring to or not?
