It's easier to understand if you look at an exampleA battery capacity is charge and discharge,2C is 3A charge and discharge,0.5C is 0.75A charge and dischargeIf the battery is 2Ah, then 1C is 2A charge and discharge,2C is 4A charge and discharge,0.5C is 1A charge and dischargeC represents the discharge rate, several C is the capacity multiplied by severalThe battery has a high rate battery, and the high rate battery can discharge above 10C, and the ordinary can only discharge within 3C1C discharge is 1 hour,2C is 0.5 hour,0.5C is 2 hours (the larger the discharge current, the shorter the discharge time)
