Lithium battery charging at or near freezing
Here's an issue I have come upon, freezing temperatures. I see the Lithium batteries will discharge down to 0 degrees F and shouldn't be charged below freezing 32 degrees F. So how would you handle...

Could running the frunace and turning on the lights for 20 minutes get the temperature up? I think insulating the outside of the step we’ll and leaving the step cover open all night may keep it above freezing. .there is a furnace duct a foot away from the step we’ll and I can direct the heat towards it or even make a vent tube and stick it down and at the batteries.. This won’t be an everyday occupancy, but maybe 5-10 times a year.
