Derive the test parameters of the battery, test and check the voltage, internal resistance, charge/discharge function in accordance with the standard

Charge with DC, test AC discharge/AC charging/unplug AC charging, UPS function works normally/LED turn on constant light, fast flash, SOS

Multiple charging and discharging, test each function and interface work normally, the battery capacity to meet the requirements, record the test data

The battery separator is used to test the capacity of lithium batteries to ensure consistent performance and enhance pack matching

Simulate battery charge/discharge cycles to detect performance degradation and screen for poor quality cells
