About using bq27z561-r1

1. Before using bq27z561-r1 for the first time, do you want to charge and discharge the battery completely and let the coulometer calibrate?

2. Where to modify the value of chem ID after modeling?

    See my comments.
    a) See the BQ27z561 EVM user's guide for the details about how to do calibration using bqStudio.
    b) Use the GPCCHEM tool to find a best matching chemistry id for your battery cell.  Use the bqStudio to program the proper chemistry id to the gauge device.
    c) Do a learning cycle after the chemistry id is programmed. See the app note below about how to do the learning cycle.
