 It is not correct, battery charging with 1.2A, what is requested by the battery controller.

@djibattworkshop I said in the explanation above
When we program the chip, everything is correct in reading the information
But when I go to the charging page and charge, the battery does not charge, and when I read the information again, the chip is back to the previous program.

RSoC is 0% because you reset the chip. 

Go to Charge Tab, start charging, wait at least 30min, Stop charging, read BatInfo page and paste a picture. 

Dont reset the chip !

Hello, the battery is charged
Just a note, the new capacity of my cells is 4400 mAh
How to adjust the chip for this capacity
My second problem is that after resetting, the capacity returns to the previous state and the date is not updated

My second problem is that after resetting, the capacity returns to the previous state

Do you mean RSoC is dropped to 0% ? 

This is specific feature of this chip with Sanyo firmware, after reset RSoC is reset too. Its need to charge a battery to full to return the RSoC to 100.
