BQ4050EVM-561: Updating the Full Charge Capacity (FCC) register

Part Number: BQ4050EVM-561
Other Parts Discussed in Thread: BQSTUDIO, BQ4050, GPCCEDV

Hi, I'm using BQstudio to monitor a battery. I have a few problems.

1) BQstudio is reading that the full charge capacity is 4400 mAh, my actual battery capacity (2S) is somewhere between 5000 and 6000 mAh. How can I update the full charge capacity? I tried completely discharging the battery, but it didn't change.

2) The temperature read by BQstudio is -273.2 C. How is this possible? how to update it? I tried enabling all thermistors, but it didn't change.

3) Does the BQ4050 normalize the capacity of the battery according to the value in Full Charge Capacity register?

Respectfully,

Elkhouly
