You ill not need to use voltage scaling with the bq20z95. Just scale all of the current and capacity values. Here is a presentation that also covers the subject, although for the other device.

Part Number: BQ40Z50 Other Parts Discussed in Thread: , GPCRB Hi,
We used BQ40Z50-R0 to design a 3S2P battery pack.
The FCC drops significantly and RSOC turns to 0 when the battery pack is discharged at low temperature.
When we changed to BQ40Z50…
Ran,
I am catching up on the e2e forum. The IPScale feature does not work properly, so you will need to use current scaling. All of the current and capacity values will need to be scaled. Here is a presentation that I used in the last Deep Dive.

TI battery gauges use the security modes SEAL/UNSEAL/FULL ACCESS in order to help protect the flash memory of the gauge from third parties reading the gauge’s configuration memory. This prevents any copying of the gauge or BMS system. The mode information…
Martin,
The gauge can be configured to support higher current and capacity packs by using current scaling. This is independent of the IPScale feature in the Specification Information register. The firmware bug causes the IPScale feature to not work…

I attached a presentation that I presented at our 2015 Deep Dive conference. It has information on scaling and the current and capacity parameters that need to be scaled. The data submitted to the GPC will need to be scaled as well.

Other Parts Discussed in Thread: BQ40Z50 In which conditions bq40z50 stops the discharge of cells (stop the DSG FET) ?
My setup is that TD and FD will set/reset only based on cell voltage , not on RSOC.
I have let my battery ( 3 series cell) to discharge…
