I am shopping around for a LiPo batteries for a robot. I found the classification of batteries confusing. I understand that higher mAh means they may last longer between charges, and that has a fairly clear definition in the Physics. Higher S rating means more cells (eg 3S = 3 cells, I think).
But I don't understand the 25C, 35C, 70C classification. I believe higher 'C' means greater rate of power delivery. So eg you can have greater acceleration in an RC car with battery 35C than 25C. What does C stand for? What is lacking is a scientific explanation, maybe a relationship between 'C' value and watts per sec ? or a quantity such a peak power (watts), or peak current with a time limit (like you get for some electronic components).
Anyone able to point me in the right direction on a tutorial / website / explain.
