The qualms I have is #1, LiFePO4 shouldn't last in freezing cold weather. We have freezing temperatures 9 months out of the year, and sometimes a snow here and there in the summer.
And #2, the housing is plastic. I don't think that would be good for thermal management.
If I could make a mold of the module housings and cast them in aluminum and add some sort of heater for the winter, I would go with these. But that seems like a lot of work. |
I know LiFePO4 should not be used in sub-freezing weather. I did, however, use one as a starter battery in Vermont's winters for a few years, and it survived. Sometimes the weather was way below zero, and the lithium pack cranked the engine over reliably, and still works to this day.
I can't account for it, and I probably wouldn't recommend it, but anecdotally...
