For the most part the only thing you need to concern
The Connecting cables need to be large enough (Same as the cable that runs off to who knows where)
And the polarity.
Most everythign else the batteries will work out by themselves
In some very high current installs there is more (Load Balance) But you are into the hundreds of amp loads before that's a concern.
With GC-2's there are additional concerns but since you are not going that route. That is all folks.
^^^ This
If you were talking about a 1500amp-hr @12v bank feeding a 3000w inverter that will be used to run the air/con or some other heavy duty system, mucking about with load balancing becomes important.
For a couple of basic 12v batteries tied together to feed minor house loads, it's largely irrelevant. Even running something like the main tongue jack might be unbalanced but as soon as the load stops, the batteries will balance themselves.

This is what is balanced and best for twin twelve volt batteries.

As it often doesn't cost a dime more to do this, I think it is worth the trouble.
If you wish to understand the "why" surf here:
correctly interconnecting multiple twelve volt batteries
Others may say it doesn't matter--but unless there is a compelling reason to not optimize charging and discharging why not do it the best possible way?
That picture was what I meant as daisy chain.
Looks like most places are recommending that setup, so I will follow that.

12v
The 2 batteries are about a year difference in age as to when I bought them.

Wondering what the addl concerns might be with 6V batteries though? You said there are concerns?
Aside from having to hook up in series or series-parallel I’m not aware of any “concerns.”
When you wire batteries in series you want Twins.. Same make, Model, Capacity, Age, as close to identical twins a possible.
Home was where I park it. but alas the.

I won't be wiring them in series as I need 12 volts and the batteries are both 12 volts.
