Thank you for the advice. I thought I would be okay because I've had a battery charger on the battery since the converter went south. It was showing 12.75v this morning, and I thought it would only go to high charge for a short time. I just went out and checked and it's showing 13.67v and we have most of the lights on. I hope it will do the trick since I put the basement wall back up and reloaded all the gear we had to take out to get to the converter. When we get home I may have to move it to a more accessible location. I'm only running one 12 volt battery.
I did read up on what you're saying about the manual and automatic settings. Sounded like you could pretty much dial in whatever you wanted. I do appreciate all the advice I've received about this. It will be very handy to know.
Good thing to know about the hat though. :)
