For BFL13 et al... FLA vs AGM vs Li vs heated Li
I have no dog in this discussion. Just passing the info: https://www.youtube.com/watch?v=iy3hga_P5YY Interesting!

Steve,
The high temperature information came from a seller, not a maker. It seems quite counter intuitive to me for a seller to post such negative information.
I decided to look for a more scholarly article. I searched for 'temperature at which damages starts on LiFePo4' and this is what I found.
"The LIBs, however, are still facing barriers that limit their application space [18], [41]. One of the major limitations is the impact of temperature to the proper operation of the LIBs. Generally, the acceptable temperature region for LIBs is -20 °C ~ 60 °C [42]. Pesaran et al. [43] showed that the optimal temperature range for LIBs is 15 °C–35 °C. Once the temperature is out of these comfortable regions, LIBs will degrade fast with increased risk of facing safety problems that include fire and explosion."
For my American friends 15 C to 35 C = 59 F to 95 F, and -20 c to 60 c is -4 F to 140 F.
There is no way I want any type of large secondary battery in my living space.
