If there are two 12 batteries wired with a parrallel connection, will the Brat charge them both, or would you need to charge the batteries separately? Also, as long as I pair a 12 volt panel to a 12 volt battery, or a 24 volt panel to a 24 volt battery, I'm assuming I can go as big as I want with a solar panel. I'm thinking about a semi-permanent charger on my dock.
I've read that some cheaper controllers can actually pull a charge from a battery if left connected after the solar panels quit charging. Fake news?
