I used electrical heating on my old solarvan project. 150w max or something. I had the lithium cells in an insulated area and used an old electric blanket underneath them. You can even dissasemble the blanket and route the heating wire around the cells/battery/box. I used a vivarium habistat thermostat to control it. Worked very well.
