Dual Pro PS4/BOS12V2 4-Bank 60A Battery Charger with 2-Bank BOS System

The Dual Pro PS4/BOS12V2 is a complete battery management solution combining a Professional Series 4-bank battery charger (60A total output, 15A per bank) with a 2-bank Battery Optimization System (B.O.S.). This kit is designed for serious boaters who need reliable charging and battery balancing for 12V-48V battery systems.

Battery Optimization System (B.O.S.) - 2 Bank:

The B.O.S. actively shuttles energy between batteries wired in series to maintain equal voltage across the pack. This intelligent balancing prevents the common problem where batteries become mismatched, limiting overall performance to the weakest battery in the system. The proprietary BSAP-24 (Battery Selection and Prediction) algorithm identifies which batteries need additional energy and automatically transfers power to maintain balance before, during, and after charging. This technology dramatically extends battery life and increases run time on the water.

B.O.S. Features:

• BSAP-24 algorithm for intelligent battery selection and energy distribution
• Transfer rate up to 7.5A between batteries
• Self-powered operation with less than 1mA sleep mode
• Compatible with any battery chemistry including wet cell, AGM, and gel
• Supports up to six batteries in series
• Available in 6V, 8V, and 12V configurations

Professional Series PS4 Charger - 4 Banks, 60A Total:

The PS4 delivers 15 amps per bank across four independent outputs, providing reliable charging for 12V to 48V battery systems. Featuring Dual Pro's DeltaVolt® Intuitive Charging Technology, this fully automatic charger adapts to battery conditions and environmental factors for optimal charging performance. The waterproof, rugged construction is designed for harsh marine environments in both fresh and saltwater applications.

PS4 Charger Features:

• Four independent 15A charging banks (60A total output)
• DeltaVolt® microprocessor-controlled charging technology
• Fully automatic multi-stage charging with maintenance mode
• Temperature-compensated for optimal performance in varying conditions
• Waterproof and ignition-protected construction (US Coast Guard 33 CFR 183.410)
• Approved for wet cell and AGM batteries (gel battery models also available)
• LED indicators show charge state for each bank
• Zero spark technology and reverse polarity protection
• On-board diagnostic codes for troubleshooting
• ISO 8846 Marine compliant and FCC Parts A & B interference-compliant
• 5-foot DC charge cables and 3-foot AC power cord included
