Cxeny LiFePO4 batteries

Anyone have any experience with these? I'm looking at 24V batteries, either two 200AH or four 100AH ones.

Many of these low-cost batteries don't mention low temperature cut-off protection, which makes me think they don't have it. We're full-timers, yes, but we prefer moderate temperatures to either high or low ones. I'm planning on moving the batteries from on the tongue to inside the pass-thru, so they won't be exposed to the weather. We haven't had the trailer long enough to know just how cold it might get in that space, but I'm guessing that it will be closer to what the inside of the trailer is like. Since the Nautilus system is in that same area, I would guess that it doesn't get all that cold. Do I really need to be concerned about the low-temperature protection? If so, what could I do? I could put a small space heater, I suppose, or look for a battery that has the low temp protection.

I'm not familiar with that battery, but low temp protection simply means that the BMS will prevent the battery from taking a charge when below a certain low temp. It is nice to have a feature to protect the battery when camping if temps could go below freezing. Since we do camping in spring and fall where temps do, sometimes fall below freezing, I went with a heated system. If relocating the battery in a heated environment, then heated or temp protection is not necessary.

You could put heat blankets on them.
