I strongly suggest going to the Battle Born website (manufacturer of DragonFly batteries) and also check out the Keystone website. There is a lot of great information on the LiFePo4 batteries on both sites, including what to do with the batteries in the winter. For what it’s worth, 41°F is the magic number, not 32°F. But fully charged and fully disconnected, they can tolerate sub-zero temperatures as long as you are not charging or discharging).
