Keep your 24V system charged and ready without adding another maintenance task. This 20-amp, 3-bank onboard marine battery charger delivers controlled multi-stage charging and long-term battery care, so you're not troubleshooting before launch.


Highlights

  • Balances Charge Across 3-Bank Chargers: Distributed-On-Demand technology sends available amps to the batteries that need it most.
  • Keeps Batteries Ready During Storage: 4-stage charging with Auto Maintain and Recondition helps prevent capacity loss over time.
  • Matches Multiple Battery Types: 12 selectable profiles support Flooded, AGM, GEL, and LiFePO4 batteries.
  • Adapts to Limited Shore Power: Selectable power levels reduce AC draw when running on constrained power sources.
  • Shows Charging Status in Real Time: Digital display provides voltage, amperage, and system status at a glance.
  • Supports Mid-Size Battery Banks: 20 Amps at 24 Volts DC supports battery capacity up to 400 Ah.

Features to know about

Charge Goes Where It's Needed

When one battery bank is drawn down more than the others, fixed-output chargers can leave the system uneven and harder to trust. Distributed-On-Demand Technology automatically senses demand and directs available charging amps to any one bank or across multiple banks as needed. On a 3-bank system, charging stays focused where it's needed, so you're not second-guessing which battery is going to lag behind.

Maintains Battery Health During Storage

Batteries that sit without proper maintenance lose capacity, and that usually shows up when you're expecting everything to be ready. This unit cycles through Charge, Condition, Auto Maintain, and Recondition stages to keep batteries at proper levels between trips. After 21 days in Maintain mode, it automatically de-sulfates to restore lost capacity, so you can leave it connected and come back to batteries that are ready to work.

Dial In the Right Charging Profile

Multi-bank systems are only as reliable as the charging profile behind them. This charger includes 12 selectable profiles and supports Flooded, AGM, GEL, Lithium (LiFePO4), and Calcium batteries with custom settings available. Matching the correct profile keeps charging behavior consistent across the system, so you're not dealing with uneven performance between banks.

Adjusts to Shore Power Limits

Not every dock or marina delivers consistent power. This unit includes selectable power levels that let you reduce AC input to 100%, 75%, 50%, or 25%. That keeps charging stable in low-power situations without overloading circuits, so you're not managing breakers just to keep batteries charged.

Monitor Output and System Conditions

Charging issues are easier to catch when you can see what's happening in real time. The digital information center displays system voltage and amperage, while built-in fault indicators alert you to wiring issues or adverse conditions. You can quickly confirm output and spot problems before they turn into dead batteries.

Runs on Standard Household Power Worldwide

Charging shouldn't depend on having perfect power conditions. This unit uses 100-240 VAC input at 50-60 Hz with power factor correction and auto-ranging input, so it works across a wide range of shore power setups. That keeps charging simple whether you're at home, at the dock, or traveling between locations.
