MPPT Settings – Rolls S6-L16 Flooded Lead Acid

I have an off-grid solar system set up with 1600w Array in two strings to two Blue Solar MPPT 60a/150v MPPT controllers feeding four Rolls 6v S6-L16 Batteries (24v series) going to Victron Multiplus 24/3000/70-50. All is OK but I'm checking daily usage/output with VictronConnect and wondered if I have the correct Battery Type settings for Charge Controller (either Rotary Switch or via Victron Connect). Don't see specific Rolls battery settings... any ideas?

@Rival

Do you have the temp sensors connected as well?

Since you have access with Victron connect you can check in the cog on the top right of it is correct.

Rolls usually charges up a bit different than other batteries so not likely to have a preset that works for them.

Probably should be at about 30v for abs and 27v for float at 25°C.

They sort of have a help article here.
