If you had 2 200+AH 6V wired together would that still be 200+AH at 12V or would it go up to 400AH? Sorry for the dumb question.

If wired in parallel, the capacity adds, the voltage doesn't. If wired in series, the voltage adds, the capacity doesn't. In series, you'd have a 12V, 200AH battery.

Yes.

Deep cycle golf cart batteries can be drawn down to a lower state of charge without damaging them. And,, I've found, just by using them that they seem to keep there charge longer.

I have a simple voltage gauge mounted inside my TT. During a big power usage, like running your furnace, the voltage will drop (of course). But, when leaving them at rest the next morning it seems to bounce back.

I don't understand it but, it has been working for me on my weekend trips for the last few years.

After I get home I plug in my TT with the converter that I bought at "Best Converters" and I charge them back up fully. I then flip the converter off using the breaker in the panel. Before I go out again I will flip the breaker back on for a few hours to give a boost to the batteries. And,,, my wire from the pickup gives them a little boost on the way to the park.

I check and maintain the battery water level once and awhile with distilled water. I clean the terminals once a year and spray them with battery protecting spray.

I keep a very close eye on the voltage level and don't let the battery set there and charge constantly when I'm plugged in. (The power converter I bought is not suppose to let that happen but, my TT is so old and the wires so bad that it does not work right)

As just a weekend camper I am happy with my results. I have about 5 seasons on my batterys now and they seem to be holding up well. ( Of course that could change at any time)

It takes a little learning. You are asking the right questions but, it takes time to understand and find a system that works for you.

Best of luck. Have a nice day.
