Different chemistries have different characteristics. BatteryUniversity says that thermal runaway on LiFePO4 is ~270C (~520F), though I'm inclined to believe that you wouldn't want to be anywhere near that for longevity.

I believe Lithium Titanate would be the safest choice if you could find some cells for a reasonable price - NASA uses them in their spacecraft, and they handle the temperature swings found in space. |
Awesome, thanks! Out of curiosity, does your battery pack have any type of BMS?
