Setting Mppt charge controller for 2 Super Start GC110DT 6V deep-cycle batteries in Series?

trying to figure out best charge controller settings for my specific batteries. everyone says read the battery data sheet but somehow that doesnt seem obvious to me.

I have 2 of these in series to make 12 V system

-(Super Start GC110DT is a 6V deep cycle Batterys with a reserve capacity of 120 minutes at 75 amps and 120 minutes at 25 amps)

What are my best settings for maximum charge current, Float absortion etc. it seems like i need to go expert mode since there isnt a preset for these batteries.

Thanks

Use the built in preset for flooded (wet) lead acid batteries.

See Super Start Fleet And Heavy Duty Battery - Super Start Battery

Recommended is to also set the automatic equalisation for 30 - 45 days.
