Pacific Automotive Network C represents the battery discharge energy, that is, the multiple of the discharge current value divided by the battery capacity value. During the charging process, the full voltage is related to the charging current. When the current is 0.3C, 3.8V can be considered full. If it is 0.1 C, it can be considered full when charged to 3.65 V.
As an example, it is easier to understand that a capacity of battery is 1.5 Ah, then 1C corresponds to a charge and discharge of 1.5 A, 2C corresponds to a charge and discharge of 3 A, 0.5 C corresponds to a charge and discharge of 0, 75A. the battery is 2Ah, then 1C is 2A charge and discharge, 2C is 4A charge and discharge, 0.5C is 1A charge and discharge, C represents the discharge rate, how many C is the capacity multiplied by how much discharge 1C is equal to 1 hour, 2C is equal to0.5 hours, 0.5C corresponds to 2 hours (discharge The higher the current, the shorter the discharge time).
Battery types are divided into high-rate batteries. High-rate batteries can discharge at more than 10 C, while regular batteries can only discharge at less than 3 C.
In a simple metaphor, C represents the explosive power of the battery. High-power batteries have a large instantaneous discharge current, which is especially suitable for situations where large currents require small size and light weight of the battery. , such as model airplanes and brushless motors.
