product descriotion temperature cutoff at -5C battery description says charge at +0C, is this a mistake?

no, Lithium batteries do not charge well at those temps. Some batteries have internal heaters that help with this problem.

This battery claims to have low-temperature (i.e., below freezing) protection. A review from 2020 says that wasn't the case then, is it now?

Yes, this battery comes with low-temp cut off protection, here is the specification sheet for your reference: https://m.media-amazon.com/images/I/B1OyZXAJndS.pdf

Burst discharge rate? i’m wondering if this could possibly replace a lead acid battery with 600cca

Our LiFePO4 batteries are not starter batteries and should not be used as such. That being said, the surge current is 100A for 10s 562-630-3002 support@expertpower.us
