Just checked the link, it does not say temperature range. It just says it has a low and high temp cut off. Now that would be bad; a cold morning and no battery! At least with the motorcycle, I could generate heat though the battery with a headlight load so it would warm up enough to crank over the engine.
The good thing is that you can bring them inside the heated area.
Temp range is anything over freezing. You can still use them if they are frozen but charging them is not advised. We have had many nights where temps dipped into the 20's but the batteries retained/stored enough heat to be over 32 degree F in the morning and good to go for charging and discharging. If one plans to spend time in frozen temps for sustained periods of time mounting the batteries in or near the heated living quarters is needed. Or, you can locally heat that compartment. One nice thing about LFP is that they don't fall off a power cliff in cold weather like led acid batteries.
On the high end they will tolerate very high temps. Well over 120 degrees.
