BQ34Z100-G1: BQ34Z100-G1

I have performed an battery chemical identification. On an 6 cell 4500mah LiPo battery. The actual chemistry is probably LiCo or LiMn.

However the GPC tool suggest 2110 as chem id which is a NiCoMn chemistry.
This is incorrect with the actual chemistry, does this mean the identification failed or can i use the data?

I have attached the GPC report as wel as the uploaded data.

    I took a look at your IVT file. It seems like the battery cell was discharged to around 3.3V. 

    When you create the log file, make sure your battery is discharged until the term voltage (as specified by the cell manufacturer) is reached.

    3.3V is specified by the battery pack manufacturer as the lowest allowed voltage during discharge.

    The battery pack i am using is a 6s 4500mah 20C LiPo used in hobby RC models.

    Would you suggest going even lower?

    I have performed the chemical identifcation again, but at a lower discharge rate.

    I still get the 2110 chem id (NiCoMn) as a best match.

    Should i use the 2110 or 1470 as a chem id?

    I have attached the data and report.

    I would recommend 1470 in your case.
