    My 2019 shows the same, I read somewhere that in gen4, they do not monitor individual banks anymore to save cost. I think it’s two banks per measurement. Apparently DrPrius accounts for that and reports the values correctly. But, mine also shows the voltage difference in the order of 8-9volts, so not sure how that part works.

    But 3 months ago when i purchased this car, i checked that day voltage difference was 0.05 but now its showing around 8.65v, the only thing i have done during this period is replaced 12v battery, can it be the issue?

    Looks like they fixed it, they said they update the app and it seems to work now showing more realistic delta voltage values 2587E3DA-AECD-43BC-98B1-0D3158398959.png

    Yes you are right, but number of blocks are still 9 instead of 14, voltage difference is fixed but why 9 blocks only?

    Ya that makes sense but in that case voltage of block 3 to 7 should be double around 30v, but dr prius is showing same volt for all blocks

    As stated before, it seems to account for that I think, and report the appropriate values..

    Can you please refer me any software other than dr prius, which shows battery voltages to confirm the same,

    I believe Torque Pro is another app that can be used, but I have no experience with that one…
