Also, keep in mind that there are different types and chemistries for batteries that effect where and how they can be deployed.
AGMs are quite different in off gassing behavior than wet cell lead acid batteries, for example. And, your house is already full of LiIon batteries which soon will reach the price and ampacity to be good coach interior batteries.

Chris commented... "Batteries should never be hooked up inside the passenger compartment as they off gas hydrogen while charging. One word?
Hindenburg."
While I don't disagree, I wanted to note that in my '75 Avion the house battery stock location is in a metal box with a foam sealed lid, that is
vented by an inch and a half diameter tube that exits less than a foot away behind the license plate.
Question: Is this stock arrangement dangerous?
Thank you!

It would appear that considerably more development is needed before I would EVER put Lithium Ion (Li Ion) batteries in MY coach. I have no desire for a "burn to the lug nuts" happening!

afaik, the LiFePO4 based Lithium batteries do not have the same
combustion issues as the Lithium batteries that are in mobile phones.

The battery business did the misunderstanding to themselves:
Lithium Ion
Lithium Iron Phosphate (the additional spaces were quite intentional)
Here’s a fairly accurate comparison:

There has been some discussion on the reluctance to use lithium ion batteries for the “house” electricity.
Some 3 years ago I installed 2, 100 amp hour Lithium ion batteries in my coach. Removed the onan, installed 4, 80 watt PV panels on the roof do do the charging, and paired with these with a 1500 watt inverter/charger to keep all in balance.
All the lighting has been changed to LEDs and with the calculations I have figured I can run:
A 1,000 watt Microwave (short bursts), a vented propane catalytic heater, an all electric frig (under counter size), nightlly CPAP use, computer, printer, portable frig/freezer, as well as all the LED lights. So far I am using both the PV panels and shore power (the inverter keeps the two doing their jobs as necessary when not plugged into shore power.
The only drawback is the absence of a rooftop AC unit. Still working on a solution to that. (being in Alberta and avoiding the hot south helps)
I am very happy with the set-up and so far there have been no issues. The Lithium Ion batteries have proven to work flawlessly and are tucked under the rear bed. No venting is required.

Peter,
Inquiring minds would like to know the manufacturer of the batteries, where you got them, their dimensions, weight, how much they
were and any additional details you might deem relevant.
