The
Cyrtix-ct is $51 US on Amazon.
It does seem considerably better than the old battery isolators these RVs came with. This one is two-way, where the originals are only one way.
However, these types of things seem to just be making a battery bank out of two dissimilar batteries which is not recommended. Especially if the two batteries are not of the same size, age, and type.
So I do wonder what the long term effects of this will be.
Ideally, I would think, each battery needs its own multi-stage charger. This is even more complicated since they need multi-stage charging both when on shore power and engine alternator power. And maybe even solar and generator power too. Yikes!
It is all hard to grasp.
