Special reminder:
Calculation of charging and discharging current for lithium batteries:
When using modules, you may encounter situations where the maximum charging and discharging current of the battery is estimated. The following explains the formula for calculating the maximum charging and discharging current of lithium batteries. The calculation formula is: maximum charging and discharging current=Nameplate capacity * C. For example, if a lithium battery has a nominal capacity of 2200mAh and a discharge rate of 2C, its discharge current is 2200 * 2=4400mA=4.4A.
