Mixing Battery Brands

My boat is going to come with 3x flooded batteries Exide ER 350 80AH with 2x being house bank and the remaining being the starter. I’d like to add one more to the house bank, however, I can’t find this battery in the US. I’d like to be able to take the third starting battery and make it a house battery and replace with some flooded battery in its place for the starter. What considerations do I need to do this? Would I need a DC to DC charger? Yandina battery switch? I have attached the wiring diagram per the owners manual where you can see that everything at factory is wired straight to the switches.

Re: Mixing Battery Brands

I dont feel it is an issue as long as the batteries have same charge profiles. My start battery isnt the same as my house batteries, been that way 10 years

So simple enough to just replace the below in for the starter battery and keep all other wiring the same?
