Adding batteries to a '74 Argosy 22 rear door

La Tortuga now has funding so things are progressing. One item I get conflicting responses on: how to safely add additional batteries.
We like to camp remote, which means no hook ups. I purchased a 200w solar array to act as a generator, but I would like to
have more amp hours than the single battery can provide.

My battery compartment is only large enough for one, so I figured I can sacrifice the bottom of the bathroom closet while also installing the new intellipower plus new DC fuse and distribution system.

Since modern batteries are sealed, the hydrogen venting is minimal. In addition, I was thinking I could fab up a box cover with a vent which would be routed to the plumbing vents which are in the same closet, which old handle any H that does vent.

Any thoughts?

Also, since the heater is toast, and my research shows the fans draws way too much amps, I was toying with catalytic.

And finally, should the water heater not come back to life, I was researching tankless water heaters for rv's.

Meanwhile I've removed all interior incandescent and LEDs are on order.

A caution: SOME modern batteries are sealed, they'll be marketed as such (SLA or Sealed Lead-Acid, and expensive AGMs are sealed as well.) "Maintenance Free" batteries not specifically listed as sealed may not be.

Modern Suburban furnaces draw less to run the fan than the old NT22s did. Of course it's still more than the zero amps that a catalytic heater requires, but if installed properly it'll keep the holding tanks warm. I guess the answer on that one depends on how cold it is before you decided to store the Argosy for the winter.

If you're really looking to save battery capacity, remember that the tankless water heaters need power for the controls and ignitor. Of course, I smugly say that while planning to buy a DSI tank water heater for the next one because the pilot light blows out too often on my propane-only Atwood...

I am working on the assumption that there will be some venting, ergo my gas-tight box lid with ductwork connecting to the plumbing vents.
Any thoughts on that?

The tankless should require only millamps but the exact value is worth noting.

The PO left a new unitrol and thermocouple for the existing water heater, we'll see how that turns out.

I installed 3 Lifeline AGM's under the side couch just over the axles in our 65 Safari. I wasn't really worried about gassing but I fabricated a box and vent anyway. I used heavy gauge wire to run back to the PD converter and fuse blocks in the rear.

We are able to go 4 to 5 days in the summer before charging. We also converted all lights to LED. In the winter or cold weather we need to charge every 3 days thanks to the furnace.

Your solar panels should help you greatly.
Good luck.

you seem to be heading down my path .... in my 24 Argosy 78 I put two AGMs with a marine switch .... I mounted one in the existing battery compartment and the other in a battery box behind the wheel well (a little closer to the axles for weight distribution). For heat, I too ditched the furnace and vents and instlalled a Wave 8 Catalytic Heater. Heat distribution is good .... slightly warmer in the front with the direct heat. Speaking of sleeping, we nap in sleeping sacks from a marine supply (Defender) .... one side summer, other winter ... removable sheets

I've got the space in the closet bottom for two more batteries, which unfortunately puts quite a bit of weight on the port side.
However, relocating the extra batts is not feasible.

Moving back towards the axle would have them under the stove. Anybody else thinks that is a bad idea? : )

AGM batteries (specifically Lifeline AGM batteries) use a recombinant technology to prevent them from out-gassing and will re-introduce any gasses back into the glass mat without them venting from the battery casing.

The exception here is if they are severely overcharged (over 15.5VDC at 77F). then, the one-way valves in the casing will open to vent the hydrogen sulfide gas. Problem is, if you ever reach this state, you have effectively reduced the amount of acid present within the glass mat and have also reduced the capacity of the batteries.

Proper charging is essential for Lifelines to avoid out-gassing. This is also the reason that you never put an 'equalizing charge' to Lifeline batteries, unless directed to do so by Lifeline tech support in the event that you have experienced reduced battery capacity.
