Hello Andrew,

Andrew Su said:

what is the function of the minimum system voltage setting? my understanding is that it is used to prevent the system voltage to drop to a very low voltage when battery is depleted.

Yes,This is correct

Andrew Su said:

but will it limit the battery to discharge below the minimum system voltage we set?

No, The minimum system voltage is used to prevent the system voltage from dropping.

Andrew Su said:

think it should not limit the battery discharging,  the battery may discharge till the system or battery protection function to disable the discharging. am i right? 

Yes,This is correct.

Best Regards,

Christian.
