I am currently using the BQ20Z45DBT-R1 IC for management of a 4-cell battery pack. As we near production of the product this is on, I am going over what will be necessary for test and calibration of the Gas Guage iC circuitry. My main question is whether or not calibration of the IC using the BQMTester (or custom test hardware and software) is required for accurate operation. If the calibration process is not performed, what kind of board to board variance should I expect?
