Batteries under Dinette Bench?

Hey, all!

I was grappling with the challenge of the limited space in the under-step battery bay for the LiFePO4 house batteries we were hoping to put in our Greyhawk 27U. As measured, the best we could manage would be 2 12v 100Ah units.

A friend suggested, "Hey...why not under the dinette bench?"

Would that be the dumbest thing in the world? Or, do those batteries need outside air to breathe? Moving the batteries under the dinette bench would mean it would be possible to move to a much larger form factor battery-wise.

Thanks for any advice!

Josh

Perfectly fine, they are pretty much zero maintenance, many installations in travel trailers are installed under the beds. The heat buildup will be from the inverter Charger of you install one, then usually ventilation is needed.

I've read somewhere that batteries release some kind of gas when recharged and it is why they're usually outside to the open air.

That is for non lithium batteries. Lithium are safe.

There is a YouTube video of someone doing that in a Jayco 212QB.

Thank You!

Thanks, gang, great input. Think I'm going to go for it!

Time to source product, will post pictures when it's done.

I am not familiar with the 27U but is your dinette in a slide? how would you run the power leads? If it was i think the additional weight of the batteries would not be good for the slide motors

OHHHHHHH....thanks, I hadn't thought of that. Yes, it's in a slide.

BUT, the jackknife sofa isn't, and it's a heck of a lot closer to the under-step battery bay. Time to go measure that out!

Look under the bed too! And don't forget to look at non-standard form factor batteries.

And your LiFePO4 batteries are going to be 1/3rd the weight of a SLA. If I did mine, they'd go under the master bed.
