Part Number: BQ34110

Hello, I've tried multiple times and no success. Zip file is attached. The battery that I'm testing is Tenergy LiFePO4.

12.8V nominal, 9.9Ah, 13.8V charge voltage, 4A max discharge.

What am I doing incorrectly?

I have tried it with the files having header row and not having header row, it didn't work either way

Thanks,

Derek

Ok I figured it out, at least to get the calculator to run. Here's what I did to get it to work. This information should be in

Simple Guide to CEDV Data Collection for Gauging Parameter Calculator (GPC) (Rev. B)

Log files must have at least one row with zero current at the beginning or ending.

The last voltage measured should be the same across all logs.

The last voltage measured should be equal to (Cell Termination Voltage * Number of Cells). So for this battery, cell termination voltage in Config.txt is 2700mV and there are 4 cells. So the last voltage measured in each logfile should be 10800.
