Solar, Blue Sea 7.3PSD question

[Mxkutch]

So I am just getting around to finishing up my electrical setup and I have a question. I have scoured the forums as well as used the search tool but have not received the exact answer I am looking for.

So I have 2 100 watt panels that go to an mmpt charge controller and I have a blue sea 7700 to connect my house and starting batteries. My house battery is a 220 amp hour AGM.

My question is should i connect the 7700 to both starting batteries that the 7.3 has, or just to one. I know the batteries are already connected, so going to one should work but is it better practice to connect them both or does it not matter?

Thank you and any added tips would be greatly appreciated.

Thanks, thats kind of what I was thinking. As for the 7700 it is amperage controlled but also has a manual override

My blue sea 7622 is connected to the frame mounted battery then to the house batteries. 0 issues and a very short length wiring.
