Without knowing the details of how your system is wired up, I'll make some presumptions.

I'll presume that it is a 12V system and then the 4 batteries are wired in parallel. Wired this way then the Ah rating does add up and then the total Ah of the bank would be 880Ah.

As long as the BMV is correctly set up with this 880Ah value set in the Battery Capacity settimg.
Then 10% would be 88Ah.

Sorry for the seemingly long winded answer, but there are various different ways to wire a battery bank which would result in different Ah ratings.
