Batteries to interior - slideout question

[EricM22]

I’m debating upgrading to lithium batteries on my 37L, and ideally putting them under the dinette seating, which is on a slideout. Want to put them inside for temperature purposes to keep them warm when camping in the winter months.

How can I handle the wiring going OUT of the slideout since it will move several feet? Is this a bad idea? What is the best way to do it so that wires will not bind and will not droop when driving down the road?

The way the slides are built, this would be difficult as you would be dealing with large 4/0 cables, welding cable is pretty flexible but I wouldn’t want it flexing in and out constantly. I installed my lithium in the small section in the front of the carpeted area which worked great. I run a small Xtreme bilge heater in this area and in 10 degree weather, this heater ran very little and kept this area 50 degrees which also kept the living area floor warmer. If this heater hadn’t worked so well, I had planned to just use the comment method of silicone heating pads or tank heating pads under the batteries and insulating this small area or just use heated batteries. It is very surprising how little heat it takes to keep the front area compartment warm.

What a fantastic idea. Thanks Rusty. That’s the way I’ll go.

For me, this area was pretty much a useless space for anything else.
