Turning off the Charging Process

What is the exact scenario?

If you disconnect the batteries from the charger when it gets cold, you still need 12v from somewhere. That would be the converter if you have shore power.

No shore power? No battery because it is too cold? Now you need another battery that does work in the cold. (SiO2 says PT :) )

Is the battery able to discharge (run loads) in the cold but just can't be recharged in the cold? (I am unclear how that is with Li)

So what is the scenario? Some have avoided this whole thing with various types of heating for their Lis to keep them in their operational zones. Not sure how you power those heater things off-grid when the batts can't be run without them. Kind of confusing!

Up to you to better describe the worrisome scenario here.

No problem DIS-charging, as in supplying AC via converter... the issue is in RE-charging. The tank warmers were initially meant to be attached, via adhesive, to water and gray water tanks, but are easily adapted to the battery bay. Further, my research suggests minimal amp needs to keep them going, and these have an on/off switch. Of course, the batteries would remain connected, for they're needed to power not just the tank warmers, but everything else inside.... and I'm thinking there will be times I'm not connected to shore power.

Reality is, I was exploring possible solutions, and looking for experience. I chose Li's for a number of reasons, and recognized early on that charging in colder temps would be problematic, but y'all are more experienced than this rookie (3 years in), and my hope was to find options I hadn't considered...

Installing the batteries inside would be ideal but for the fact there's no place to hide them except the ward in the bedroom, or, the drawers under the dining bench seats - valuable storage to sacrifice...
