  • Hi Jerry,

    Thank you for the description, screenshot of the registers window and the gg.csv file. Please send a log of what is occuring and describe your expected behavior.

    Please change FC set = -1 and ensure that FC is setting when fully charged.

    From the screenshot we can see that the pack is properly learned. Qmax is currently over 17000 mAh.

    Please try decreasing the value of Flash Update OK Cell Volt to 0 to ensure that all writes are being made to dataflash.

    Sincerely,
    Bryan Kahler
