Definition

Capacity-rate refers to the charge or discharge current based on the nominal capacity of the battery in ampere hours (Ah). This provides information about the maximum load/discharge a LiPo battery can be subjected to. The C rate describes the rate at which a battery is charged or discharged relative to its maximum capacity. It is expressed in terms of “C,” where 1C represents charging or discharging the battery at a current that would fully charge or discharge it in one hour. For instance, a 1C rate for a battery with a capacity of 1000mAh means charging or discharging it with a current of 1000mA (or 1A). Consequently, a 0.5C rate would imply a slower rate of 500mA, taking two hours for a full charge or discharge cycle.
