Dual Pro RS4 4 Bank Battery Charger w/3 Bank B.O.S.

The RS4 4 Bank Battery Charger with 3 Bank B.O.S. is an essential kit for marine enthusiasts seeking reliable power management for their watercraft. This comprehensive system ensures your batteries remain balanced and fully charged, providing optimal performance and extended battery life during your boating adventures.

Included Components

This kit features Dual Pro’s cutting-edge technologies: the B.O.S. Battery Optimization System (12V, 3-Bank, PN: BOS12V3) and the RealPRO Series Battery Charger (24A, 4-Bank, PN: RS4). Together, they offer a robust solution for maintaining and charging multiple batteries in marine applications.

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

The B.O.S. Battery Optimization System actively manages energy distribution between batteries to maintain balance within the battery pack. This proactive energy shuttling enhances battery strength and longevity, ensuring that your boat's power systems remain reliable.

In marine settings, where trolling motor batteries often support peripheral systems or assist cranking batteries, maintaining balanced voltage across the battery pack is crucial. The B.O.S. continuously monitors and equalizes the voltage, preventing any single battery from becoming the weakest link.

Key benefits of the B.O.S. include:

• Balanced battery packs for maximum performance
• Extended battery life through optimized energy distribution
• Quadrupled run time on the water
• Advanced BSAP-24 algorithm for precise battery selection and prediction

By addressing premature battery failure caused by unbalanced packs, the B.O.S. ensures each battery operates at its best, providing reliable power for all your marine needs.
