Minn Kota On-Board Precision Charger MK-345 PCL 3 Bank x 15 AMP LI Optimized Charger
Minn Kota On-Board Precision Charger MK-345 PCL 3 Bank x 15 AMP LI Optimized Charger Product Description
Unlock Peak Performance for Your Boat's Batteries
Picture this: you're gearing up for dawn patrol on your favorite fishing spot, but a dead battery sidelines your plans. With the Minn Kota MK-345 PCL, those frustrating mornings become a thing of the past. This powerhouse 3-bank charger delivers 15 amps per bank, fueling your 12V lithium LiFePO4, AGM, or flooded lead-acid batteries with smart, tailored precision. Anglers swear by it because it slashes charge times while extending battery life, letting you chase bass or stripers without the downtime.
What sets it apart? It's not just charging—it's revitalizing. Lithium batteries, lighter and longer-lasting than traditional lead-acid, demand specific curves to avoid damage. This unit wakes sleeping lithium cells from standby and adjusts on the fly, ensuring every electron counts toward more hours on the water.
Smart Features That Think Like an Angler
Every bank operates independently, so you can mix battery types—one for your trolling motor, another for electronics, and the third for starting power. Here's how its tech edges out basic chargers:
- Per-Bank Battery Selection: Dial in lithium, AGM, or flooded lead-acid for each bank. No guesswork, just safe, optimized charging that prevents overvoltage or sulfation.
- Temperature-Smart Charging: Sensors detect heat or cold swings—common in garages or marinas—and tweak the charge rate. This means faster top-offs in summer swelter or winter chill without risking battery health.
- Voltage Stability Magic: Shore power flaky? It compensates for dips below 120V, maintaining steady output so you charge reliably from any outlet.
- Equalization for Lead-Acid: Routine cleanings desulfate plates automatically on plug-in, with a manual deep clean button for neglected batteries. Lithium users skip this, staying in multi-stage bliss.
- Digital Brainpower: Microprocessor control orchestrates multi-stage cycles—bulk, absorption, float—for pinpoint accuracy. LED lights keep you posted on progress, errors, or full charge.
Pro tip: For tournament anglers, pair it with high-draw lithium setups. It revives "dead" LiFePO4 packs that other chargers ignore, saving you from costly replacements.
Rugged Design Built to Withstand the Elements
Boats endure spray, bumps, and salt air—this charger's waterproof, shockproof shell laughs it off. Mount it onboard or in your rig; it's vibration-resistant for rough trails to the launch. Saltwater anglers, rejoice: full compatibility means no corrosion worries. At 9.25 x 11 x 3 inches and 14.5 lbs, it's compact yet beefy, with ring terminals for secure, no-fuss connections.
Running 700W from shore AC, it powers through 3-5 hour charges for typical group 24 or 27 batteries. Backed by a rock-solid three-year warranty, it's peace of mind in a box.
