And using BQ78350-R1 + BQ76930.
I am a 60 [A] want to change the Design Capacitor mAh to 60000 mAh.
In TI, that can be used to change the settings 320000mA was Ido design capacity
Unchanged.
Do BQ78350-R1 has a maximum depth of up to 32A?
I want at least 32 [A]. Please let me know the solutions will favor Dream.
Thank you.

    The maximum current that the device can support without current scaling is 32A. It can support 32Ah without scaling as well. You will need to use 2x scaling to support the 60Ah pack. If you need to support 320A, then you will have to use 10x scaling. Here is a document that discussed current and capacity scaling.

    Hi ThomasCosby
    I received your daily fine.
    Bq34z100 , I know the battery capacity divided by 4x information well in 29 000 [A] or more.
    Now I do not understand the datamemory caribration part in bqsutdio software well.
    For example, assume that the battery capacity is 100A, and tell us how to How to Calibrate for Current Scaling specifically
    You must attach a picture file.

    "BQ78350-R1"

    The point I want to question the value of a variable changes in Qmax Pack = 100A. Data Memory There are 32,767 [mA] up to the value of the variable.
    I want to change 32,767-> 320,000 in the picture.
    32,767 I can expand the capacity of the battery [mA] I want to use more than 100,000 [mA]. Is Tell us more about 4x scaling bingbeop in the Data Memory is going to change in BqStudio software? Please ask you dream.
    Thank you
