I found a very good youtube video on lithium vs lead acid. It is by an engineer who did extensive side by side testing in the lab where he could get consistent results for each battery type he tested. It is somewhat long but very thorough.

It was done at BattleBorn but the results are the same for other manufacturers.
Thanks for finding and posting this.
Unfortunately they did not cycle the lead acid batteries BEFORE testing.
Lead acid / agm are rated at 25 amps discharge, so testing at 40 amps is not a level playing field.
The low voltage cut out is interesting. I wonder if going to 10.5 UNDER load is the same as discharging capacity to 10.5 volts?
Last winter because of snow cover my house bank went to 8 volts. It has recovered nicely.
I do use my rv at -34 f so Li unfortunately won't be in my future.
