Dual Pro SS3 3 Bank Battery Charger w/3 Bank B.O.S.

The SS3 3 Bank Battery Charger with B.O.S. is the ultimate solution for marine and boating enthusiasts seeking to optimize their battery performance and longevity. This comprehensive kit combines the advanced Battery Optimization System (B.O.S.) with the robust Sportsman Series Battery Charger, ensuring your vessel's power systems remain balanced and efficient, even in the most demanding conditions.

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

The Battery Optimization System (B.O.S.) actively manages and balances energy distribution between your batteries, enhancing overall pack strength and extending battery life. In marine applications, where multiple batteries often support various onboard systems, maintaining balance is crucial to prevent premature battery failure and ensure consistent performance.

How B.O.S. Enhances Your Battery Pack

B.O.S. continuously shuttles energy between batteries connected in series, ensuring equal voltage before, during, and after charging. This dynamic balancing significantly increases run time on the water by preventing any single battery from becoming the weak link in your power system.

Traditional battery packs often suffer from imbalance, especially when auxiliary systems like trolling motors or peripherals draw power from the same batteries used for starting the engine. B.O.S. addresses this by using a sophisticated BSAP-24 algorithm to predict and adjust energy distribution, thereby extending the lifespan of each battery and optimizing overall performance.

Key Features of B.O.S.

• Available in 6V, 8V, and 12V configurations
• Supports up to six batteries in series
• Advanced Battery Selection and Prediction (BSAP-24) algorithm
• Ultra-low power consumption with less than 1mA sleep mode
• High transfer rate of up to 7.5A
• Self-powered design
• Compatible with any battery chemistry

Applications for B.O.S.

• Marine and boating power systems
• Golf carts and utility vehicles
• Industrial battery setups
• Aerial equipment power management
• Solar power systems
• Electric vehicles
• Communications infrastructure
• Defense and military applications
