    The CC Offset parameter must be outside the range allowed by the bqStudio setup . Try placing this bqz file in the config directory and reopen bqStudio. I lower the threshold allowed by the program.

    C:\ti\BatteryManagementStudio\config

    Hi thomas,

    Thanks for your quick reply.

    Earllier i have golden image for 4000 mAh battery, but due to change in application we are going to use 2600 mAh battery.

    We want to create new golden image for 2600 mAh battery.

    Kindly guide us with steps to create the golden image for 2600 mAh battery.

    If you want to use the same basic set of parameters, then you can follow these steps.

    1. You will need to find a good ChemID match for the new cells. Use the GPCCHEM tool to find the a match.
    2. Export a gg file from the pack. Set the Update Status and both Cycle Counts to 0. Update the Design Capacity parameter.
    3. Program the default srec into the device.
    4. Program the updated gg file into the device.
    5. Program the ChemID.
    6. Calibrate the pack .
    7. Enable IT.
    8. Run the optimization cycle.

    You can now create the golden pack.

    1. Export a gg file from the pack. Set the Update Status to 2 and both Cycle Counts to 0.
    2. Program the default srec into the device.
    3. Program the ChemID
    4. Program .the updated gg file into the device.
    5. Export the golden srec file.

    .
