The battery tested turned out that it had no low temperature cut-off. Will Prowse has done similar tests with the same results for the cheap batteries. If you plan on using the battery and know it will not get down below freezing it would be a good choice.
No Thanks!
Another Minnesota resident that finds a low-temp shutoff mandatory.

I don't know about that, laitly I have been finding the prospect of getting a battery with out the low temp shut off more desiriable, let me explaine.
if the battery comes with it and it actavates it totaly kills the battery. LFP batteries may not want to be charged much below 0, but they can be discharges to -20 for most of them... so in my mind it is almost betyter to build you own cold weather protection system that does two things. use a thermostat controled relay to shut off ny charge power at say 1 degree C ( battery temp not outside temp, as most of the time the discharge will keep the batteries above this temp) then you still have your ability to discharge and run stuff in the camper also warming up the battery. you could have a second relay that at -20 disconects the battery totaly and have them a normaly open relay so if there is a problem they fail open (disconected) you could also add one for a battery warming system that turns on and cycles the heat between set temps. you could use something like an ardunio or a raspberry PI to build one of these that would be reliable and cheep.
