The Minn Kota MK-440 PCL is a 4-bank, 40-amp on-board charger engineered specifically for anglers running 12-volt lithium (LiFePO4) battery systems alongside AGM or flooded lead-acid banks. Each bank is independently configurable to match its battery chemistry, and a microprocessor-driven multi-stage charging algorithm delivers a full charge in 4–6 hours while actively compensating for temperature swings and low-line voltage. Waterproof, shock-resistant construction makes it a reliable permanent installation in any marine environment, including saltwater.

Features:

• Per-bank battery type selection for Lithium (LiFePO4), AGM, or flooded lead-acid chemistry — guarantees a safe, protected charge for each bank
• Automatic temperature compensation senses ambient conditions and adjusts the charge curve for consistent accuracy
• Low-line voltage compensation maintains a fast, steady charge even when AC outlet output falls below 120 volts
• Battery equalization mode cleans and conditions flooded lead-acid batteries on every charge cycle; a manual button triggers a deeper equalization cycle on demand
• Microprocessor-based digital control delivers a faster, more precise charge and can automatically wake dead 12-volt lithium (LiFePO4) batteries from standby
• LED indicator lights communicate charge stage, maintenance mode, error notifications, and charge completion status
• Automatic multi-stage charging manages voltage and current throughout the full cycle for a fast, safe result
• Waterproof, shock-resistant, and vibration-resistant construction built for permanent on-board installation
• Backed by a full 3-year replacement warranty
