Does that make sense. Like a 25C battery will give more runtime than an equal mAh size 40c.
This may be a lot of repeat information, but this is the first thread I've read that was dedicated to the subject and remained on topic.

No, you are incorrect.
Higher C rated batteries have less internal resistance, and less heat is generated if the CURRENT draw is the same. Higher C rated batteries are more important as the number of cells and voltage go down because more CURRENT will be required by the motor to turn the same RPM which generates more heat in the battery, speed control and motor!
At higher voltages the CURRENT draw goes down if the motor is sized appropriately.
TOO MUCH CURRENT (heat) is what kills motors, speed controls, and causes batteries to puff or fail!
