Dual Pro SS3 Auto 3 Bank Battery Charger w/2 Bank B.O.S.

The SS3 Auto 3 Bank Battery Charger with 2 Bank B.O.S. is the ultimate solution for marine enthusiasts looking to optimize and maintain their boat’s battery performance. This comprehensive kit ensures your marine batteries remain balanced, extend their lifespan, and deliver reliable power whenever you hit the water.

B.O.S. Battery Optimization System - 12V - 2-Bank

The B.O.S. Battery Optimization System actively manages energy distribution between your boat's batteries, ensuring each battery in the series remains balanced. In marine applications, where trolling motors and peripheral systems draw power from the same battery pack, maintaining balance is crucial for preventing premature battery failure and maximizing performance.

How It Works

B.O.S. continuously shuttles energy between batteries wired in series, balancing the voltage before, during, and after charging. This ensures that all batteries in the pack operate at optimal performance levels, quadrupling your run time on the water.

Key Features

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