Explanation
C is used to indicate the magnification of battery charging and discharging capacity. 1C represents the current intensity when the battery is fully discharged within one hour. If a 18650 battery with a nominal capacity of 2200mA · h is discharged at 1C intensity for 1 hour, the discharge current is 2200mA. Charge discharge magnification=charge discharge current/rated capacity; For example, when the battery with rated capacity of 100A · h is discharged with 20A, its discharge magnification is 0.2C. The discharge rate of the battery, 1C, 2C, 0.2C, is a measure of the discharge rate of the battery: indicating the speed of discharge. The capacity used is discharged within 1 hour, which is called 1C discharge; After 5 hours of discharge, it is called 1/5=0.2C discharge. The capacity of a battery can generally be measured by different discharge currents. For a 24A · h battery, the discharge current at 2C is 48A, and the discharge current at 0.5C is 12A.
