Part Number: BQ27426EVM-738
I'm trying to create the golden image for a 10000mAh 3.85V (max charge 4.4V) battery. From my understanding, I have to:
However, I'm having trouble with step 4: when I enter the Data Memory menu, Chemistry menu, State submenu, BQStudio complains that the value 10000 is out of range for the design capacity. Is this the correct way of configuring the device?
That means the design capacity you are trying to use is larger than what that gauge can support.
You will have to try using the scaling method described in section 3 of the app note below otherwise your next best bet will be to use any of our flash based gauge like the bq27520 which can support greater than 10000mAh batteries:

replace 0426_2_02-bq27426G1.bqz file with the the attached file in the config folder of bqstudio. This will open allow program > 10000mAh in the gauge.
That file indeed allowed me to set a capacity of 10180mAh, but now I cannot set the proper design energy (39193mWh).
