I googled it and now understand what it is and how it works but am mystified how it might work in my dual battery situation.
I wonder if my idea of adding a simple switch in the solar panel line to the CC would work adequately to isolate the panel from the CC when disconnecting one of more of the batteries.
If the PTC or light bulb are better if charging both in parallel on one of the outputs from the duo charger then that would free up the second output for a third battery or bank!
Is there a diagram of the PTC and bulb circuit I could see?
