Hi,
1. Make sure that the input capacitors (C6+C12) and system capacitors (C17+C18) meet the system power requirement as explained in the schematic check list here. You may need more capacitors at the system output.
2. Make sure that SDA and SCL lines have 10kOhm pull up resistors.

Thanks for your support, and the output is Li battery 3S2P, is that parameter correct for this application?
Hi,
For 3S battery the CELL_BATPRESZ pin should be above 55% of VDDA. In your schematic it is ~58% which is correct for your battery configuration.
