C rating is a rating of how quickly energy can be discharged from a battery.  The rating is combined with a battery’s capacity to find determine the maximum discharge.   This is very important when you consider battery choices for Quadcopters and multi rotors because these machines draw very high amps from the motors and it is easy to choose a battery that can’t handle the currents required by brushless motors and steep-pitched props.

The C rating is important when it comes to choosing a battery for high performance multi rotors because our multi-rotor motors draw high amounts of current (amps) and it is very easy to choose a battery that is not properly rated for our current draw.  The C rating is proportional to the battery’s capacity,  so as you move up in capacity, you can move down in C.

When engineering a new quadcopter, we have to consider the amp draw of the motor/prop combination, and the max battery size we can fit on the quad to determine the right battery for the job.

The available power is calculated at 80% because most drone motor Throttle/Current curves are linear up to this point.
