BMS display show cell 4 is 0V yellow4th cell reading is good from here, 3.6V
the reply helped.
You can try to use 6s in this system to test again.
1.The default is 3 and it is not auto detect..
2. they are working after I set the number of cells to 6.
Now it looks ok after the number of cells are set to 6.
also attaching the configurations:
cell 3 reading is 3.6V and bms display also shows 3.6V
