BQ24780S: Battery FET

Part Number: BQ24780S

Hi,

Please see diagram in datasheet below. The application I am working on does not need SYS to be supplied by the battery, when the power adapter is off even if the battery is still connected the product should be off. In that case can I remove Q3, R12, the 4.02K resistor on BATDRV pin, D1 and D2. This will mean that VCC will only ever get power from the adaptor and there is nothing connected to BATDRV and BATSCR.

Thanks
