Minn Kota MK-330D 3 Bank x 10 Amps

Keep your boat's batteries primed for every adventure with the Minn Kota MK-330D, a rugged 3-bank on-board charger delivering 10 amps per bank for a total of 30 amps of reliable power. Designed for serious anglers and boaters who demand non-stop performance, this charger uses smart digital technology to monitor and optimize every charge cycle, ensuring your 12V batteries—whether flooded lead acid, AGM, or lithium LiFePO4—are ready when you are.

Why Boaters Trust the Minn Kota MK-330D for Peak Performance

Unlike basic chargers that plug in and hope for the best, the MK-330D stands out with its microprocessor-driven intelligence. It tracks ambient temperature, battery state-of-charge, and more to deliver charges up to twice as fast in hot conditions. This means shorter recovery times—typically 4-6 hours for a full recharge after a long day on the water—getting you back to fishing or cruising without delay. Its automatic shut-off prevents overcharging, extending battery life and saving you money on replacements over time.

Key Features That Set It Apart

• Multi-Stage Charging Mastery: Progresses through bulk, absorption, and maintenance phases for a complete, safe charge without stress on your batteries.
• Smart Temperature Compensation: Adjusts charging rates based on environmental conditions, preventing under- or over-charging in sweltering summers or chilly mornings.
• Clear LED Feedback: Real-time displays show charge progress, maintenance mode, errors, and full-charge status—no guessing games.
• Triple Bank Design: Independently charges three batteries simultaneously, ideal for multi-battery setups in bass boats, pontoons, or center consoles.
• Built for Brutal Conditions: Waterproof aluminum housing resists shock, vibration, and saltwater corrosion, standing up to the harshest marine environments.

Seamless Compatibility for Modern Marine Batteries

This charger handles a wide range of 12V batteries rated from 40-130 amp hours, including flooded/wet cell, maintenance-free, AGM, and lithium LiFePO4 options. Whether you're powering a trolling motor, electronics, or lights, it adapts to your setup. Connect via ring terminals with included fused output cables, and plug into standard 120V shore power—fully universal for effortless integration into 12V, 24V, or 36V systems.

Effortless On-Board Installation and Daily Use

Mount it right in your battery compartment for a clean, permanent solution that beats lugging around portable units. Its compact footprint (16-1/4 inches long, 7-1/2 inches wide, 4 inches high) and 20-pound build make it sturdy yet unobtrusive. Pre-wired with 6-foot cables, setup is straightforward: secure the mount, connect to batteries with positive and negative leads (observing polarity), and route the AC cord to your outlet. Built-in protections against short circuits, reverse polarity, arcs, and ignition keep operations safe.

Engineered Durability for Year-Round Reliability

Crafted with saltwater-tested corrosion resistance and vibration-proof construction, the MK-330D thrives where others fail. It's FCC compliant and UL-listed to marine standard 1236, backing its 3-year limited warranty with proven toughness. Boaters report it handling everything from tournament trails to family outings without a hitch, maintaining peak output even after seasons of heavy use.

Real-World Tips for Maximizing Your Charger's Potential

To get the most from your MK-330D, always charge batteries promptly after use—don't let them sit depleted. In extreme heat, its digital smarts shine by ramping up amps safely. Pair it with quality batteries matching its specs for optimal longevity. Regular checks on connections ensure peak efficiency, and those LED codes make troubleshooting a breeze, like spotting a bad connection before it strands you.

Equip your vessel with the Minn Kota MK-330D and experience charging that matches your passion for the water—reliable, fast, and tough enough for whatever comes next.
