Bq40z50: battery capacity update

Hi：

I used the "04A9019-2017-6-12.gg.csv" to do learning cycle twice times for 10pcs of cells(2S1P), but all of cells have been updated same 2900mAh.

What's problem in 04A9019-2017-6-12.gg.csv?

Most folks are out for the July 4th Holidays. We should get back to you after the break.

Che yi Su,

I reviewed your attached file and it appears you already have had a successful learning cycle completed on that file. Update status is 02 and your Ra status is 00FF. Since you have learning completed, you just need to extract your golden srec which you will program on multiple devices and the devices will learn their individual cells resistances and qmax while in the field.

thanks
Onyx
