Our trailer has a battery compartment that is not heated. I have looked at putting lithium batteries in our heated basement but the space that would be available would make it difficult to get to the batteries and would require rewiring a lot of items that currently go to the battery compartment, possibly having to increase wire size due to the longer runs. If we change to lithium, I will have to calculate the price difference between non heated and heated vs changing the wiring and coming by up with a way to access the space in the basement.
We were is Southern Texas last Feb so cold temps can hit anywhere.
I would like to know how much the heated batteries use in power to keep them above the temperature to charge them.
