I'd like to install lithium batteries somewhere inside our trailer but I don't have a lot of options. I'm considering under the bed or possibly in the cabinet behind the TV, but I'm not sure what if anything is back there. If nothing is back there I'm sue that I'd have to build something to support them. I am also considering leaving them up front in some sort of secure, heat-able box.

I'm wondering where others put their lithium batteries.
