Please remember that both the upper and lower limits for charging are not the outside or ambient air temperature it is the temp inside the actual battery.

If your batteries are equipped with BMS to shut off charging at 24-32 degrees it is unlikely that you will ever actually see it stop charging unless your batteries are outside and the temp has been below freezing for several hours..

I regularly camp during the winter and I didn't buy nor was it recommended by Battle Born that I buy the heated batteries for my trailer. I keep them in the un-heated front compartment.
