2020 Bus 37AP AGM Battery Question

I'm still getting familiar with my new to me bus.

It has the upgraded battery package that appears to be 6 Lifeline AGM 6CT batteries that are 6v 300ah each and wired in series--I think that means I have 12v 900ah with 450ah of the being usable?

The Spyder battery settings are set to AGM but the Amp Hours are set to 600 (with 700, 800 and 1000) being the other higher available settings.

If I'm correct in having 900ah, is there any benefit to my updating my settings to 800 or 1000?

Thank you in advance for your help!

Yes. 900ah gross, 450ah net usable.

The battery bank AH setting is likely used to set the time in absorption charging stage. Pretty sure it's wanting the gross AH of the battery bank to calculate from. If the time in absorb cannot be explicitly set, I'd increase the gross battery bank AH to better match.

If you could provide a photo of the bank of batteries? I suspect that your battery bank is wired in series-parallel to provide 12v power.

The other 450Ah are usable too.

There are " NET " and " GROSS " battery AH ratings ????

Can someone show me where #s like that are listed ?

I understand that, like gas, some like to only use half of what they have, but that's a personal choice. You can use it all.
