BQ27541-V200: BQ27541-V200

Part Number: BQ27541-V200
Other Parts Discussed in Thread: BQ28Z610

Hi,

The BQ27541-V200 fuel gauge is used inside Li-Ion battery. In my application, I need to use two similar batteries in series.  

After the series connection of batteries, I am able to read I2C of second battery whose GND is connected to the Board. NOT able to read I2C of first battery.

I understand that as the GND of first battery is connected VBAT of second battery the reference of first one is shifted to VBAT. How to resolve this.

Thanks,

Kaliga.
