I use the clean gg file to record the data below the setting：
1. battery charge at 25oC, rest 2 hr, use 2A discharge until voltage < 3.2V at 25oC(terminate voltage = 3.2V), get the data：P28A 2A-3200mV rb 20240509 - 25oC
2. battery charge at 25oC, ship to -30oC, rest 2hr, use 2A discharge until voltage < 3.2V at -30oC(terminate voltage = 3.2V), get the data：P28A-3200mV rb 20240508 - -30oC
report the record data to Ti GPC tool, and get the reply rb report, and I import the rb file to gg.file, I notice the first problem：the Qmax original is 5640mAh, but the rb file modify it to 2811mAh, the setting causes my FCC to display extremely low data at room temperature.
Therefore, after manually modifying Qmax and change it back to: 5400mAh, i did two tests:
a. At 25 oC, using 2.8A & 1A discharge, get the record： P28A-3200mV rb 2.8A & 1A test at 25oC 20240514.log
b. At -30 oC, using 2A discharge, get the record： P28A rb test - -30oC 20240515-fail
It can be clearly seen that at 25 degrees, 2.8A & 1A discharge are smooth, and the curves are correct.
but after the temperature dropped to -30 degrees, the FCC still showed the wrong capacity.
After 2A discharge, the capacity jumped from 27% to 0%. Although the FCC was corrected to 3360 mAh after the discharge (3540mAh was actually discharged at -30 degrees), But as the temperature slowly rose, the FCC was forced back to 46xx mAh
the second problem：is there any setting that needs to be changed to make the low temperature curve and FCC display normally?
