There are some top end manufacturers/retailers that offer models that can be charged down to -4F/-20C without damage, by borrowing some of the charging current, and self heating the batteries. Both Relion and LifeBlue make such a battery. There may be others.
I have 2 X 100 Ah Relion RB100-LT batteries (charged by 3 X 100W ZAMP panels off grid) and so far so good. We don't worry about running out of power any more.
