How did you connect the first cell? Did you add two separate wires for GND and C0? If not, you could get a measurement error because the internal power supply current goes through the cell balancing/measurement wire.
I have verified with my hardware and the cell voltages are all very accurate (including the first one). Fluke measurement is same as cell voltage measurement through BMS with deviation of +-1 mV.
Thank you for your help. After I checked the schematic diagram, I found that I did not connect bat -, which would cause problems in the measurement. I have solved the problem, and the result is very accurate.
During the test, I found that the error of battery 1 was a little large. The voltage measured by the multimeter is 3.83V. How should this be adjusted?
