With three selectable charging modes—12V, 12V AGM, and 12V Lithium—the charger adapts to flooded, gel, AGM, SLA, VRLA, maintenance‑free, and LiFePO4 lithium batteries. Whether you’re powering a car, marine vessel, trailer, or RV, this solar charger offers a smart, reliable solution for all your 12‑volt battery needs.
