Hello Sir

If we would like to use BQ27426 with 8m ohm current sense resistor, how to set up the coulomb to get correct current value

In data sheet, the fuel gauge is precalibrationed for a standard 10m ohm 1% sense resistor, if we change sense resistor to 8m ohm, what should we do to get correct coulomb counter?

Hello,

You can complete the current calibration to get the correct coulomb counter. Please see my last response.
