Hi Danilo,
Upon review of the schematic everything on the BQ24072 looks okay, although the customer mentions on the schematic they want to ISET = 863 mA, but R14 connected to ISET is 3K. To set ISET = 863 mA R14 should be 1.03 Kohms.
There are a few things which need adjustment on the BQ27520-G4. A ground connection should be added between C13 and C17. The SRP pin needs to be connected to the battery pack (-) terminal (labeled LiIon- on customer schematic) and SRN needs to be connected to ground instead of battery pack-.
