Hi Davydd,
I have not seen a rating for lower than 20 F on LI. I RV at -34 F. LI are not suited to that sort of temperature. If I'm wrong that's great.

Wrong. They do better in cold weather than lead-acid batteries. What you cannot do is bulk charge them in below freezing weather. Solution. Insulated heated battery box. Besides, few Bs are designed for use in sustained over 24 hours below freezing temperatures and I doubt many use their Bs in sustained below freezing temperatures.
