The Minn Kota MK-220 PCL is a 2-bank, 10-amp-per-bank on-board charger built around lithium LiFePO4 optimization — delivering charge curves engineered specifically for the high demands of lithium batteries while remaining fully compatible with AGM and flooded lead acid banks. Per-bank battery-type selection, automatic temperature compensation, and low-line voltage correction work together to keep charge times tight and battery life long, whether you're running one chemistry or two. Waterproof, shock-resistant construction makes it a reliable permanent install on any vessel.

Features:

• Per-bank battery type selection covers Lithium LiFePO4, AGM, and flooded lead acid — each bank charged with its own optimized curve for a safe, protected result
• Automatic temperature compensation senses ambient temperature shifts and adjusts output to maintain charge speed and accuracy
• Low-line voltage compensation corrects for outlets delivering less than 120V, keeping charge output consistent regardless of power source quality
• Battery equalization (flooded lead acid) cleans and conditions the battery every cycle and supports a deeper manual equalization cycle at the push of a button
• Microprocessor-based digital control manages voltage and current throughout every stage of the charge cycle; also capable of waking dead 12V lithium LiFePO4 batteries from standby automatically
• LED indicator lights report current charge stage, maintenance mode, error notifications, and full-charge status
• Automatic multi-stage charging sequences voltage and current delivery for a fast, precise, and battery-safe charge every time
• Waterproof, shock-resistant, and vibration-resistant housing engineered for permanent on-board installation
• Backed by a full 3-year replacement warranty
