BQ33100: 4 -CELL CONFIGURATION

Part Number: BQ33100

Hi team,

I am using BQ33100 in my design for a 4-cell configuration. For implementing the cell balancing feature i referred the application schematic given in the datasheet, a snippet of the same is attached herewith. The application schematic is for a 5-cell configuration, so the implementation of the last cell balancing is a bit confusing. Should i use the last cell external cell balancing configuration as in the first snippet or the one without the 20k,10k resistor network, as in the second snippet? Can anyone help in this regard.

                                    

Thanks & Regards,
