Rate of Discharge: The discharge rate of a lipo battery is often specified by a ''C'' rating, which describes the rate at which the battery can be safely discharged. For example, a battery with a 1C discharge rate can be discharged at a current
The C-rate, a measure of the charge and discharge current relative to the battery''s nominal capacity, was set to 3C, meaning the battery pack was discharged at three times its nominal capacity. Under this 3C discharge rate, the discharge duration for the battery pack was 1200 s.

For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power.
The capacitor charges when connected to terminal P and discharges when connected to terminal Q. At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero. As a capacitor discharges, the current, p.d and charge all decrease exponentially. This means the rate at which the current, p.d or charge
