If you want to lean into all of that Will Prouse has a fairly extensive
library of videos on YouTube tearing into various batteries and battery
assembly.  I think he is more focused on home power banks and server
rack batteries, but there is a tremendous amount of practical knowledge
there.  I don't recall if Will has torn into the portable power pack
market to the same degree, but its worth a look see.

Thanks. Will's reviews convinced me to buy 2 of the the LiTime Mini 12V 100Ah, LiFePO4s which fit in Group 24 boxes although they are slightly taller than lead-acids. They are spares kept ~75% charged for typically long but fairly predictable hurricane and ice storm outages, i.e. charge full, then discharge by 20 to 25Ah, which is overnight on my 12VDC freezer. Charge to BMS cutoff when a storm is predicted.
I use replaced-on-schedule medical AGMs for daily cycling to comply with the IRS rule that batteries listed for tax credit on Form 5695 must be charged purely from renewable sources, while used ones from flea markets etc aren't eligible for the credit and thus can be charged with grid power in bad weather like today's.
