LiFePO4 is much better with full charge to discharge, repeatedly, and I don’t have to worry about coming back to a car in flames
I'm not so sure I'd say it's "much" better, but it does have a higher and flatter discharge curve which makes it easier to design around and use. As far as "flames" you needn't worry- I can personally attest to LiIon 18650's handling high heat quite well, as there was one in the console of my old Buick when an engine bay fire destroyed the car in front of my eyes, and the cell saw at least several hundred degrees for several minutes before it vented with flames. Pretty solid for safety I'd say I don't know of any 'clinical' tests for LiIon degradation due to storage and use in high heats thgough that does happen- also happens to LiFePo4 to a lesser degree. The big issue now is sourcing good LiIon18650 cells cheaply- they're not air-shipped to the US from China anymore
Either will do as long as you know what you're doing.
