Dual Pro RS3/BOS12V2 3-Bank Battery Charger with 2-Bank BOS System

The Dual Pro RS3/BOS12V2 is a complete battery charging and optimization system that combines a RealPRO Series 3-bank charger (18A total, 6A per bank) with a 2-bank Battery Optimization System (B.O.S.). This integrated solution is designed for marine applications where maintaining balanced battery packs is critical for maximum performance and longevity.

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

The B.O.S. technology actively shuttles energy between batteries wired in series to maintain equal voltage levels before, during, and after charging. Batteries in a pack naturally become unbalanced over time, and the pack's overall performance is limited by its weakest battery. This is especially common in marine applications where trolling motor batteries are used for accessories or to assist cranking batteries. The B.O.S. uses a sophisticated BSAP-24 algorithm to predict which battery needs additional energy and automatically balances the pack, extending battery life and increasing run times up to four times.

B.O.S. Features:

• Works with 6V, 8V, and 12V battery configurations
• Supports up to six batteries in series
• Battery Selection and Prediction (BSAP-24) algorithm
• Energy transfer rate up to 7.5A
• Less than 1mA sleep mode for minimal battery drain
• Self-powered operation
• Compatible with all battery chemistry types

RealPRO Series 3-Bank Charger (RS3):

The RS3 delivers 18A total output across three independent 6A charging banks for 12V-36V systems. This charger is engineered for everyday use in bass boats, pontoons, runabouts, and other watercraft. Each bank operates independently with fully automatic charging and maintenance mode to keep batteries at peak performance.

Charger Features:

• Universal input voltage (100-240 VAC 50/60Hz) for worldwide use
• Approved for Wet Cell and AGM batteries
• Waterproof, rugged construction suitable for fresh and saltwater
• Independent LED indicators show each battery's charge state
• Fully automatic operation with battery maintenance mode
• Reverse polarity protection
• Ignition protected (US Coast Guard 33 CFR 183.410)
• ISO 8846 Marine standards compliant
• FCC 15 Parts A and B interference compliant
• 5-foot DC charge cables and 3-foot AC power cord
• Two-year warranty

Applications:

• Bass boats and fishing boats
• Pontoon boats and runabouts
• Other marine watercraft
• Golf carts
• ATVs and recreational vehicles
• Automobiles

This system provides an affordable, reliable solution for boaters who need advanced battery management without the complexity of installation restrictions. Simply plug it in and the system automatically handles charging and optimization.
