Victron Energy lead-acid batteries: the AGM Deep Cycle series at 12V in 8Ah, 14Ah, 22Ah and 38Ah, plus the larger sizes in the range, built with absorbed electrolyte and a regulating valve.
AGM is still the sensible choice in a few specific cases: when a starter or standby battery has to sit for months with no electronics awake, when budget is the main constraint, and when the battery has to deliver very high inrush current for a few seconds.
The limit is depth of discharge: below 50% cycle life collapses, so for the same usable energy you need twice the nominal capacity of a LiFePO4.
