BQ76905: 4S application questions

Part Number: BQ76905

Tool/software:

Hi experts,

Good day! My customer is using BQ76905 in 4S project and have below 2 inquiries:

1. They connect following datasheet as below. For cell3, which cell voltage register is corresponding? The voltage for cell1~4 is 2V, 3V, 2V, 2.5V, read cell1~5 voltage register value is 2V, 3V, 2V, 2.5V, 2.5V. Cell 3 voltage does not match with cell4 voltage register. Why?

2. For above cell connection, what's the corresponding cell balancing demand for cell3 and 4? Customer is confused how to match cell3&4 with datasheet third, fourth, fifth cell. 

BR,

Victoria
