I converted my TT to 2-6 volt flooded golf cart batteries and a upgraded converter from Best Converters. This was about 2 years ago. I dry camp once and awhile but, not to often. I have been very happy with this set up.
Last fall on my last trip of the season I was going to dry camp and when I got to the park I was low on voltage. I was shocked and a little worried. When I got home and put the TT in the shed for the winter I cleaned the posts and added water. The water level was not below the cells though it was a little low. I figured I must have made a mistake and not had the TT plugged in all the way before I left for my final trip of the season and that is why I had low voltage that time.
I've been keeping a eye on the voltage all winter as I usually do. I don't leave the converter on. It doesn't like to go into float mode. So, I flip it on once every few weeks to charge things up hen turn it back off.
I charged everything up about 3 weeks ago when it was 15 degrees f outside then shut the converter down . The voltage hovered around 12.9-13 volts for the first 2 weeks. This week the temp went up to 40 degrees f outside.
My battery voltage is now 13.9 volts :E with the converter off and no load on the batteries.
Is this normal ? I can't seem to find a answer on the internet.
(I wonder if the cheap volt meter that I have plugged into the cigarette outlet inside the TT is acting up ? )
Thank you for any responses you can give.
