  • Hi Zell,

    What is your question? It looks like the temperature readings are very close (BQ GUI Test result). Which reading are you using from BQStudio - is it the TS1 temperature? Have you run the BQ769x2 Thermistor Coefficient Calculator to configure the device for your NTC? Can you share your register settings (save .gg.csv file from BQStudio Data Memory screen) so we can see how your temperature protections are configured?

    Thanks and best regards,

    Matt
