Dual Pro SS4 4 Bank Battery Charger w/3 Bank B.O.S.

The Dual Pro SS4 4 Bank Battery Charger with 3 Bank B.O.S. is the ultimate solution for marine enthusiasts seeking reliable and efficient battery management. Designed specifically for marine and boating applications, this powerful charger ensures your batteries are always balanced and ready for extended adventures on the water.

Product Overview

The SS4 4 Bank Battery Charger kit includes Dual Pro’s advanced Battery Optimization System (B.O.S.) - 12V - 3-Bank (PN: BOS12V3) and the robust Sportsman Series Battery Charger - 40A - 4-10A-Banks - 12V-48V (PN: SS4). This combination ensures optimal battery performance, longevity, and balanced power distribution, making it an essential addition to any marine power setup.

Battery Optimization System (B.O.S.) - 12V - 3-Bank

The Battery Optimization System actively shuttles energy between batteries to maintain balance within your battery pack. By ensuring each battery operates at equal voltage before, during, and after charging, B.O.S. significantly enhances battery strength and longevity.

Key Benefits of B.O.S.

• Prevents imbalance in battery packs, ensuring the pack's overall performance is not hindered by weaker batteries.
• Ideal for watercraft applications where the trolling motor battery is used for peripherals or to assist the cranking battery.
• Extends the life of each battery within the pack, providing quadruple run time on the water.

Advanced Technology

B.O.S. utilizes the BSAP-24 algorithm to accurately predict and select the battery that requires additional energy to match the other batteries in the pack. This intelligent management system ensures each battery remains in optimal condition, preventing premature failure and enhancing overall performance.

Features

• Available in 6V, 8V, and 12V configurations
• Supports up to six batteries in a series
• Battery Selection and Prediction (BSAP-24) algorithm
• Less than 1mA sleep mode for energy efficiency
