Minn Kota On-Board Precision Charger MK-440 PCL 4 Bank x 10 AMP LI Optimized Charger - 1834401

Minn Kota MK-440PCL Precision On-Board Charger | 4-Bank x 10 Amp (1834401)

Power your entire marine battery system with the professional-grade Minn Kota MK-440PCL Precision Charger. Featuring 4 independent banks and a high-speed 40-amp total output, this charger is specifically optimized for Lithium (LiFePO4) batteries, making it the ultimate power solution for 36V trolling motor systems plus a dedicated 12V cranking battery.

Precision Performance for Multi-Battery Systems

The 1834401 model is engineered to provide a perfect charge to every battery in your boat, regardless of chemistry. Because each bank is digitally controlled and independent, you can charge a mix of battery types—such as three Lithium batteries for your trolling motor and one AGM battery for your engine—simultaneously. The MK-440PCL ensures that no battery is undercharged or overcharged, protecting your investment and maximizing your time on the water.

Key Features:

• 4 Independent Charging Banks: Manage up to four 12V batteries at once. Perfect for 24V or 36V systems with additional house or starting batteries.

• Lithium (LiFePO4) Optimized: Features a dedicated charge profile to ensure Lithium batteries reach a full charge safely. It even includes a "wake-up" feature for batteries in BMS standby mode.

• Multi-Chemistry Support: Each bank features a selectable dial, allowing you to choose the correct profile for Lithium, AGM, or Flooded Lead-Acid batteries independently.

• 10-Amp True-Rated Output: Delivers a consistent 10 amps per bank for rapid recovery times between fishing trips.

• Automatic Temperature Compensation: Sensors adjust the output voltage based on ambient temperature to prevent battery damage in extreme heat or cold.

• Low-Line Voltage Compensation: Designed to deliver a full, steady charge even when using long extension cords or when dockside power is fluctuating.

• Battery Equalization & Desulfation: Automatically conditions flooded lead-acid batteries to prevent sulfation and extend overall battery life.

• IP68 Waterproof Construction: Fully potted and sealed to protect against water, salt, shock, and vibration in the harshest marine environments.
