The cell spec sheet for most Lifepo4 cells say to not charge below 0c and it is wise to limit charging as you reach freezing. If you want to bypass the safety feature of your BMS you could remove the temp sensors and warm them up separately from the cells.

Click to expand... If it is report 8c, it is not limiting your charging due to temprature
