Recommended Battery Warmer Wraps For Lithionics G31 130Ah Batteries

Question:

I have two Lithionics G31 130ah batteries in my Airstream Flying Cloud. I dont want to de-install them this winter. Can you recommend heating blankets/pads for these batteries? I have access to both 30amp shore power and regular 110 electric where the trailer is stored. Thanks, John

A Lithionics G31 130AH battery would be 11.93" long x 5.91" wide so the best option would be to use two of the Kat's Heaters Thermal Battery Wrap # KH22200. With these wraps being 36" in length you would have just enough to fully cover each battery without overlap.

Personally I would plug the whole camper into shore power so that your converter is still powered and can properly charge up the batteries while in storage and just run the battery wrap lines to an outlet in the camper. Since there isn't a button on these to turn them off you'll want to get a timer from you local hardware store, like you would use for your Christmas lights, so periodically shut the wraps off since they're not meant for constant use.
