It seems that LFPs have a wider operating temp than lead-acid batteries. But I see your point. As with any batteries, an increase in temp corresponds to a decrease in expected life. But then, LFPs are rated for thousands of charge cycles compared to lead-acid's hundreds. So even with non-ideal temps, I think LFPs would still come out on top in terms of performance and longevity.


lifepo4 is a type of li-ion. so yeah lifepo4 is a li-ion battery. there are other li-ion chemistry out there like NCA, NMC, etc.

i've seen ads by readygo. i wonder how long they actually last inside a hot engine bay.
