The Minn Kota MK-345 PCL is a 3-bank, 45-amp total on-board charger optimized for 12-volt LiFePO4 lithium batteries — while also supporting AGM and flooded lead-acid chemistries. Per-bank battery-type selection, automatic temperature compensation, and microprocessor-driven multi-stage charging keep each battery receiving a precise, protected charge every cycle. The digital control system can even recover a dead lithium battery from standby automatically, and waterproof, shock- and vibration-resistant construction makes it a reliable permanent install on any vessel.
