1. What would happen, if the capacity exceeds the max rated capacity of the gauge? 
2. How would this impact the…

Hello! 

From section 7.26 of the BQ28z610-R1 datasheet, it states there is a 3.3k pull down on I2C. Can you elaborate on this PD? Could the voltage divide from the external I2C pullup and not be in compliance to voltage level requirements…

Hi team,

I would like to know how much is the reading deviation (+/-%) of V_CELL? I understood the temperature is one of the factor, so that I want to know the total accuracy of V_CELL including ADC error.
