I totally agree that the 150c claim is totally ridiculous but there is IMHO a perfectly good basis for batteries with discharge rates far higher than 10-15c.

For instance, my 3D models run 4 cell 2200mAh batteries. I get about 7 minutes of mixed flying from them which is an 'average' discharge rate of about 10c. However my peak amps in these planes which I use during some aerobatic manoeuvres is 60A, which translates to a little over 27c. The batteries are actually rated 30c.

So my point is you cant simply take the flight time in minutes and divide that into 60 to get your required C rating, unless that is you fly the entire flight on constant power, and where would the fun be in that?
