-40 is what I have seen. I will look for a source. The numbers you have been looking at are from lab testing for either minimum operating temp or minimum charging temps. Lab results are different and probably should be. I doubt there is regulation involved other than possible safety issues. Bob
PS your search should include LiFePO4. Each lithium chemistry has different stat's
