Hello

We do not recommend adding a diode between BAT and battery.

The BQ24210 will monitor battery voltage at the BAT pin, voltage drop due to resistance or diode will increase this voltage and prevent proper charging. Some problems will be early transition from CC to CV mode at 4.2V, longer voltage taper and charge time.
