This guy gets into it. By far the best I have seen. Anyone seriously considering LiFePo4 should watch this video.
I love my LiFePo4 system so far ..... I would have liked some of this info when I did my research.
Good BMS discussion as well. RELiON offers a low temperature series which would certainly interest some folks.
At the beginning, he mentions “they are a little bit heavier” ... I am not sure what he is referring to as a comparison. I took a chance with this “newer tech” because they are so much lighter than most of the standard batteries. Like, half the weight, to begin with, & secondly, you get 90%+ use of the listed AH.
In summary this video offers, beginning to intermediate thoughts, about availabile options.
