What fuel gauge, and primary protection parts are best to use with the BQ2057 2 cell Lion charger. The cells, charger, fuel gauge and protection chips all reside on the same PCB.

Hi Daniel,
What is your application and how much accuracy are you expecting to get from the gauge? Do you have access to the mid-point of your battery?
Two gauges to consider are the bq28z610 and the bq34z100-g1

thanks
Onyx
