BQ34Z100-G1: BQ34Z100-G1 ChemID=4127 FCC incorrect

Hi Good day : 

we using ChemID=4127, battery capacity should be 9000mAh, 

the Studio UI to reading show FCC is 885mAh incorrect,

then execute discharge with dynamic 3A, the capacity is quickly used to 0%~ 

this ChemID learning problem or have other parameters must be to setting??

thanks a lot.
