thanks, i pulled them from the trailer, have them sitting in the basement out of the way. Apparently out of the way also includes not being charged

Certainly it will be better until some SOC level, hard to say exactly what as that will depend on your converter but I will find out the story for mine. But some of this is really overblown. There is really no reason to go to all of these great lengths with manual adjustments and connections. Get a good converter, make sure the batteries are watered, make sure that everything is working and keep your SOC is between 50% or 80% and 100%. I will telll you that it takes a long time to get the last 5 or 10 percent, which is why solar is so helpful. A Trimetric will tell you where you stand at each and every moment. Getting low, run the generator or plug in. In your case with solar, enjoy the sunshine and watch your SOC climb back all the way up.

This isn't black magic, but with only the 4 little red LEDs on the panel, you really don't know where you stand at all.

All you have to do beyond that is enjoy your RV.

Is a #4 strained wire heavy enough to connect the two 6 volts in series? Or maybe I should also be asking if #8 is heavy enough for the converter to the batteries about 10' distance.

You can find a 4/0 ga 17" battery connect everywhere.
Easy and thick.
I would use as big of wire from the converter as you can fit into it.

Thanks Kenny, that's what I've got on it now. Seems to be ok. I'm think the most amps will be while charging with the generator and the onboard converter.

That just doesn't sound right.
What I am saying is that a converter in Stage 2 and a 10 amp dedicated battery charger will charge a deep cycle battery to float in the same amount of time.

Don't use stranded wire. You need solid battery cable. I got mine at Walmart. They have battery cable in 2, 4, and 6 gauge sizes at reasonable prices. 4 gauge is perfect for the job.

Since you are using the studs for your trailer, leaving the posts open.

There is a nice DC table at http://assets.bluesea.com/files/reso...on_chartlg.jpg

I would consider the converter "critical" as voltage drop reduces charge current and lengthens recharge time. Unfortunately FR did not do this with my converter which is a 70 amp unit and is 22 feet from the bank and is wired with #6 S/B at least #4 and perhaps even #2. At least they could have grounded the negative to the chassis to cut the drop in half.

All of my "inter battery" cables are #4, most auto supply stores sell #6 but those cables are not for RVs. They are very short, however, so the voltage drops are minimal.

You do have to be sensible here, a 70 amp converter will spend a small portion of its lifetime trying to output 70 amps.

Yes, thanks, I'm going to check my wire size and length today
