Strange, the explanation is done by a website that belongs to a company that has a better solution than common isolators. Are they giving you the real deal or just trying to sell you something....?
No batteries are exactly alike. They WILL pry on each other, or loose power, or many other problems. Ergo my suggestion, install 2 6V batteries and avoid buying the BETTER isolators all together...
The only reason we isolate batteries on an RV is that we are afraid (sometimes with good reason) that we will draw down the camper battery so much that it will, in turn, draw down the starter battery to the point that we cannot start the vehicle. Thus the market is full of products designed to separate starting batteries from camper/RV/house batteries. Each of these products has advantages and disadvantages. As a general rule, however, you do not want to isolate the batteries in your camper battery bank one from the other. In fact, I can think of no good reason to do so.
Sorry, but no. In most (if not all) the starter battery is in a completely separate circuit. You can't drain your starter battery, no matter how much you drain your house batteries.
We isolate them so they don't pray on each other. You don't like diodes? Fine, use relays. But I can assure you, there are several of them already running in your RV, sucking your power as we speak....
Jokes aside, you can avoid this all together by using two 6 volt batteries.
As far as the 8 volt batteries, if you will use them, invite me for when you plug them in, I always enjoy a good firework show...
