Hello John,
The bq27z561-R2 does have a hibernate mode if they implement the new firmware. The gauge will have to calculate the gauging parameters again upon wakeup, that's why it will take several hours to recalculate the SOC and other parameters.…
Hello Gaberiel,
I was able I've attached the Release Notes for the firmware and you are able to view each changes within the firmware. We push our users to use the most updated firmware and we don't have the bandwidth to do a deep dive into what changes…

I have exported a .gg.csv file from a bq27z561-R2 gauge. I wish to write it to another gauge, but I do not want to overwrite calibration data. I realize that I could delete…
Hello Sai,
I would recommend looking at the BQ27z561-R2 if you only need gauging for a single cell. It uses the impedance track algorithm and is flashed based with the highest configurability.
If you want to implement your own gauging then you can…
