Because during braking the ESC has to dump power back into the battery. Packs with poor C ratings have high internal resistance, so to get the power back into the battery the voltage has to rise. The lower the internal resistance of the battery (higher C rating) the lower the voltage drop during accelleration, and the lower the voltage rise during braking.
