I reviewed your gg file. You have the Number of Series Cells set to 7, but the Voltage Divider is set to 37994 mV. That would mean that the maximum cell voltage is 5.4V. Is this true? Did you go through the Design Steps starting on page 28 of the datasheet. Step 3 provides guidelines to setup the external resistor divider. If you are using our EVM, then you will have to change the resistor divider resistors to support 7 cells.
