I notice that the stock battery for my FC40 has a 20C discharge rate. My 2700 mAh battery has a 35C discharge rate. I assume the FC40 discharges a battery at 20C or less. Does using a battery with a higher discharge rate affect the performance of the quad or the battery? I also assume that using a battery with a lower discharge rate can overload the battery and cause it to fail. Is this right?
