Minn Kota MK-550PCL Precision On-Board Charger | 5-Bank x 10 Amp (1835500)

Power your entire vessel with the ultimate marine charging solution: the Minn Kota MK-550PCL Precision Charger. Featuring 5 independent banks and a massive 50-amp total output, this charger is specifically optimized for 12V Lithium (LiFePO4) batteries, making it the premier choice for professional anglers and boaters with complex 36V or 48V trolling systems plus dedicated house and cranking batteries.

The Multi-Bank Masterpiece

The 1835500 model eliminates the need for multiple chargers. Whether you are running a 36V trolling motor system alongside a 12V house battery and a 12V cranking battery, the MK-550PCL handles it all. Each bank is digitally controlled and can be set to a different battery type, ensuring that every individual battery in your fleet gets the specialized care it deserves.

Key Features:

• 5 Independent Charging Banks: Charge up to five 12V batteries simultaneously. Perfect for 24V, 36V, or 48V series/parallel configurations.

• Lithium (LiFePO4) Optimized: Formulated with specific charge curves for Lithium batteries, including a unique feature that can "wake" Lithium batteries from BMS-induced standby mode

• Selectable Battery Types: Mix and match your battery chemistry.⁵ Set each bank independently to Lithium, AGM, or Flooded Lead-Acid.

• 10-Amp Output per Bank: Provides a rapid, true-rated 10-amp charge to each battery, significantly reducing downtime between trips

• Automatic Temperature Compensation: Built-in sensors adjust the charge based on ambient temperature, protecting lead-acid batteries from boiling in the heat or undercharging in the cold.

• Low-Line Voltage Compensation: Maintains a consistent charge even when shore power is weak or when using long, low-quality extension cords.

• Battery Equalization: Automatically cleans and conditions flooded lead-acid plates with every charge to maximize capacity and life.

• Durable & Waterproof: IP68-rated waterproof construction that is saltwater-tested and resistant to heavy vibration and shock.
