Yes the Hersey relay is wired in parallel and connects both banks.
And your thought about the lithium battery is correct in that they can accept much more charge.
In fact that may be what caused the failure of my isolator.
I installed 3 200ah lithium’s about 4 months ago.
“They are drop in replacements say’s the battery salesman”
Well, if you read the fine print in the lithium charging instructions, at the bottom of the page (of course, wouldn’t want to make it obvious). You will find warnings about charging with an alternator!
In conversing with Richard who has also went the lithium route. He tells me that he has disconnected his lithium’s from the isolator. And depends on the inverter for charge of the lithium’s.
I’m not sure of my alternator size, I think it is 300 amp that seems to be pretty common in the Newell’s. The isolator I have is 300 amp that I know.
So in summary, if you want the ability to charge from the alternator. You need not only a large isolator, you also need a regulator capable of regulating both voltage and current to protect your alternator.
Richard tells me he has researched this and that type of regulator is expensive.
So I think I will follow Richards path to a solution.

I have not disconnected the lithium’s. I will check that out, and let you know my experience.
