Test method:
Wait a few seconds after installing the battery, read the battery data, and the battery voltage and internal resistance parameters will be displayed. There will be a delay in data loading during the battery loading and unloading process. Check after the data stabilizes
About capacity test:
The discharge must be completed to measure the capacity. I have never met anyone who w
