Samlex 15A Battery Charger - 24V - 3-Bank - 3-Stage w/Dip Switch & Lugs

The Samlex 15A Battery Charger – 24V – 3-Bank – 3-Stage with DIP Switch and Lugs is a professional-grade marine charging solution engineered for vessels, RVs, and off-grid power systems that demand reliable multi-bank battery management. This fully automatic three-stage charger handles all 24-volt lead-acid battery types—flooded, AGM, and gel cell—making it the versatile core of any serious boat's electrical infrastructure.

The three-bank architecture enables independent charging of multiple battery banks from a single 120V 60Hz or 230V 50Hz AC input, critical for managing house banks, engine start batteries, and auxiliary loads simultaneously without cross-discharge. Three-stage charging—bulk, absorption, and float—optimizes battery lifespan by precisely controlling voltage and current throughout the charge cycle. Dip switch configuration allows conversion to a two-stage algorithm for DC UPS operation on vessels with live DC loads, or use the unit as a standalone DC power supply. The 15-amp capacity delivers fast recharge times suitable for offshore fishing trips, extended cruising, and high-demand marine electrical systems. Integrated lugs provide direct battery terminal connection, eliminating reliance on shore power connectors and reducing voltage drop in the charging circuit.

This charger serves serious boaters who run multiple battery banks—whether weekend anglers with engine start and fish-finder power, or liveaboard cruisers managing house, thruster, and auxiliary systems. It's equally at home in RV setups, off-grid cabins, and marine electrical installations where multi-bank charging without intelligent switching is the standard. The dip-switch flexibility bridges traditional marine and modern UPS applications, making it a foundation component for vessels transitioning between AC dock power and DC-loaded systems.
