Hi Andrew,

1. With a 4s1p configuration utilizing lithium ion cells, please set the Flash Update OK Voltage to 1000 mV.
2. Factory Calibration is discussed in detail in Chapter 5 of the TRM found here: http://www.ti.com/lit/sluubf7
3. Impedance Track gauges use ChemID. For the 'chemID' (CEDV gauging parameters) for the bq34110 please use the GPCCEDV tool found here: http://www.ti.com/tool/GPCCEDV

If you have any other questions, please let me know!

Sincerely,

Hi Hao,

As mentioned in the previous answer, factory calibration is discussed in detail in Chapter 5 of the TRM found here: http://www.ti.com/lit/sluubf7

In bqStudio, you click on the Calibration Tab.

In this tab you are able to calibrate:
1) CC Offset
- Procedure described in section 5.5 of the TRM
2) Board Offset
- Procedure described in section 5.6 of the TRM
3) Temperature
- Procedure described in section 5.8 of the TRM
4) Current
- Procedure described in section 5.10 of the TRM
5) Voltage
- Procedure described in section 5.9 of the TRM
