C represents the charge and discharge rate, 1C represents 1200 mA (1 time 1200 mAh), then 30 C represents 36,000 mA, 50 C represents 60,000 mA and 60 C represents 72,000 mA .
Generally, the size of the charge and discharge current is often expressed by the charge and discharge rate, that is: charge and discharge rate = charge and discharge current discharge/rated capacity, for example: when a battery is equipped with; a rated capacity of 100 Ah is discharged with 20 A, its discharge rate is 0.2 C. The discharge rate of the battery C, 1C, 2C, 0.2C is the discharge rate of the battery: a measurement discharge speed.
:When a lithium-ion battery is discharged, its operating voltage always changes over time. Electrode potential refers to the electrical effect of a solid material immersed in an electrolytic solution, that is, the potential difference generated between the surface of the metal andthe solution. This potential difference is called the potential of the metal in the solution or electrode. potential. In simple terms, the electrode potential represents the tendency of a certain ion or atom to gain electrons and be reduced.

< p>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 battery capacity is 1.5 Ah, then 1C corresponds to a charge and discharge of 1.5 A, 2C correspondsat 3A charge and discharge, 0.5C is 0.75A charge and discharge. the battery is 2Ah, then 1C is 2A charge and discharge, 2C is 2A charge and discharge and 4A discharge, 0.5C is 1A charge and discharge, C represents the discharge rate, how much C is the capacity multiplied by how much discharge 1C is 1 hour, 2C is 0, 5 hour, 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 particularly suitable for situations where large currents require small size and polight battery ids. , such as model airplanes and brushless motors.
