Advice Please – Installing Lithium LiFePO4 batteries in a ’14 Discovery 40E

[Captain Morgan]

My 6 lead acid house batteries are shot and I'm going to replace them with Lithium LiFePO4 batteries. I will eventually install solar panels, but that'll be a separate project.

The batteries are at the rear of the coach and the back side of the compartment is wide open to the engine area. I'm trying to figure out how to close out this compartment so I can heat it when the temperature drops below freezing. I also want to vent it if it gets too hot while driving down the road, especially being so close to the engine.

Does anyone have any experience with closing out/insulating this compartment? Any ideas?

I really don't want to relocate the batteries to another compartment or inside the coach.

FYI: I've searched various on line resources but can't find anyone that's done it to a '14 Discovery 40E. I'm posting this on a couple of sites/groups, so my apology if you see this post more than once.

Not specific to enclosing that compartment but a thread I did on my upgrade. Might want to look as it has some things to consider when you do yours.

Perhaps another way to do this is to install or buy batteries already installed in, insulated boxes, complete with low power draw 12 volt heating pads.

I think they are out there.

If you post 2 or 3 good pic's from different angles of what this area looks like you'll probably get some good suggestions. Pictures are worth a 1,000 words.

Thanks Computerguy, I'm reading through your post now.

I installed 600ah of Lifeblue batteries with internal heaters. Plus they have built in bluetooth monitoring.
