In general this is correct, not all lithium chemistries fall into that exact spec. BB batteries can charged down to I believe it's 27 or 24 F. The OP's choice is pretty new to the market and it's been difficult to find specifications. Keeping your batteries above freezing however is by no means an engineering feat. Hard styrofoam insulation, aquarium or 3D printer bed heating blankets along with a relay and thermistor... Voilą. If you camp in very cold weather often then I would recommend mounting them inside your coach in a more climate controlled area.
