Switching out three 12vdc to four 6vdc batteries.
Has anybody done it and taken a photo of (new) cable(s) placement.
What brand and model of 6vdc did you use? I have seen it at a rally and know it was a very close fit. Want max ah. 08 Tour.
Thanks, Kerry
Tried to use the search feature, but coach batteries was too numerous.

Here is a picture from another post. (not my post or coach).
On my 2007 Tour, I replaced the 3 regular batteries with 4 AGM GPL-6C's. They are taller but fit perfectly and give plenty of power for dry camping. Notice that you will have to put some spacers in to keep everything tight.

sorry no picture avalable but I did do it in a suncruiser and the battery bank is under the steps. I had to modify the electric stair bracket a bit. Grind some away so it didn't hit the bottom corner of the battery but its a tight fit and it works. Sams club batteries. I changed out 2 twelve volt to 4 six volt batteries. Hooked 2 6v together in series then both banks toghether in paralle. much more lasting 12v power.

just wondering how you check the water level in those back batteries in the 07 tour. Doesn't look easy to me.

In general, AGM batteries don't require watering unless you abuse them. Many are sealed. Those look like they might be Lifeline's, which rarely need water.
But yeah, if you were to use flooded batteries, you might consider one of those remote watering systems. Otherwise, step one is remove the front two batteries!

I like that "In general AGM's don't need..." Actually there is no way to add water to an AGM. it's a sealed Valve Regulated Lead Acid type battery.
I will make it easy.
Take two six volt batteries,, On one of them hook a jumper wire (Same size as the power wires that will go off it when you are done) to the positive terminal, hook the other end of this wire to the negative terminal on the other battery.
You now have a 12 volt battery. Think of this joined pair as a single 12 volt battery and all your questions are answered.. Just that fast.
There are not six volt batteries in RV's... Just 12 volt batteries that are split in 2 for easier handling.
Now.. Once you remove them, or more precisely once you remove that jumper THEN they go back to being six volt batteries.. But always treat the pair as a single 12 volt.

We used to have a set of AGM's that you could add a DI water and catalyst solution to replace liquid lost over long operation in very dry climates, which we did. You are correct in that the cover isn't just a passive vent, but part of the system to recover electrolyte gas. In general, they should not be opened by anyone not familiar with servicing them, and you would likely void any warranty by breaking the seal.
Sorry if I created confusion.
