Dual Pro SS2/BOS12V2 2-Bank Battery Charger with B.O.S. System 20A 12V/24V

The Dual Pro SS2/BOS12V2 is a complete battery management solution combining a 2-bank Sportsman Series charger with the advanced B.O.S. (Battery Optimization System). This kit includes the SS2 20-amp charger delivering 10 amps per bank and the BOS12V2 2-bank optimization system, designed specifically for marine and powersports applications where battery balance is critical.

B.O.S. Battery Optimization System

The B.O.S. system actively shuttles energy between batteries wired in series to maintain equal voltage levels before, during, and after charging. This prevents the common problem of battery packs becoming unbalanced, where the entire system is limited by the weakest battery. The proprietary BSAP-24 (Battery Selection and Prediction) algorithm continuously monitors and redistributes energy to ensure maximum performance and significantly extended battery life.

B.O.S. Key Features:

• 12V configuration for 2-bank systems
• Transfer rate up to 7.5 amps for efficient balancing
• Self-powered with ultra-low sleep mode (less than 1mA draw)
• Compatible with all battery chemistries including wet cell, AGM, and gel
• Extends battery life and increases runtime by maintaining pack balance

Sportsman Series SS2 Charger

The SS2 charger features DeltaVolt intuitive charging technology with fully automatic, multi-stage charging for optimal battery health. Waterproof and rugged construction makes it ideal for marine environments in both fresh and saltwater. Advanced microprocessor control ensures safe, efficient charging with LED indicators displaying real-time charge status.

SS2 Charger Features:

• 20-amp total output with independent 10-amp banks
• Approved for 12V and 24V systems with wet cell and AGM batteries
• Zero spark technology and reverse polarity protection
• Temperature-compensated charging for accuracy in varying conditions
• Battery maintenance mode prevents overcharging
• On-board diagnostic codes for troubleshooting
• Waterproof, fully automatic operation
• Meets ISO 8846 Marine standards and US Coast Guard ignition protection requirements
• FCC Parts A & B interference-compliant
• 5-foot DC charge cables, 3-foot AC power cord

Applications:

Perfect for bass boats, saltwater fishing vessels, pontoon boats, trolling motor systems, golf carts, utility vehicles, and any application where multiple batteries are used in series. The B.O.S. system is particularly valuable in marine applications where the trolling motor battery is also used for electronics and accessories.

This combo kit provides professional-grade battery management with the reliability that has made Dual Pro the preferred choice of boat manufacturers and over 750,000 satisfied customers. The repairable, serviceable design ensures long-term value and sustainability.
