It's actually 20°F. You don't want to charge LiFePO4 batteries when their below 20°F. Freeze they should be fine.
My LiFePO4 batteries have lasted so long because they are not in the engine compartment.

I've been planning to relocate the battery to the former spare tire well in the trunk. It doesn't look like these lithium batteries can take the high heat of an engine compartment, from what I'm reading and what you all are saying.
I am in Coastal Southern Cali... It almost never ever freezes here, except high in the mountains. 20*F has quite probably not happened at my garage location in 20,000 years! Lol
