After the internal storage of the battery is discharged and the voltage reaches a certain value, continuing to discharge will cause over discharge. The discharge cutoff voltage is usually determined based on the discharge current. The discharge cutoff voltage is usually set at 1.0V/branch for 0.2C-2C discharge, and 0.8V/branch for 3C or above discharge, such as 5C or 10C discharge. Battery over discharge

It may bring catastrophic consequences to the battery, especially high current over discharge or repeated over discharge, which has a greater impact on the battery. Generally speaking, over discharge will increase the internal pressure of the battery, damage the reversibility of positive and negative active substances, and even if charged, it can only partially recover, resulting in a significant decrease in capacity.
