Common Concerns Answered
Is the B.O.S. system complicated to set up?
While the B.O.S. system employs advanced algorithms, its wiring connections are typically straightforward. The manual provides detailed guidance, and marine-grade connectors ensure a secure and optimal installation for effective battery balancing.
Is 6A per bank sufficient for my large battery bank?
The 6A per bank is optimized for maintaining battery health and standard charging cycles, particularly when paired with the B.O.S. system's balancing capabilities. For extremely large banks requiring rapid charging, higher amperage chargers might be considered, but this unit excels at battery longevity and performance.
The price is higher than basic chargers; is the B.O.S. truly necessary?
The Dual Pro B.O.S. system actively prevents premature battery failure due to imbalance, a common issue in multi-battery configurations that significantly extends overall battery lifespan and can effectively quadruple run time. This proactive maintenance offers long-term cost savings and superior system reliability.
Frequently Asked Questions
What is the B.O.S. Battery Optimization System and how does it work?
The B.O.S. (Battery Optimization System) is Dual Pro's proprietary technology that actively monitors and equalizes the voltage across batteries connected in series. It intelligently shuttles energy between battery banks using its BSAP-24 algorithm to ensure all batteries maintain optimal charge levels, preventing imbalance that leads to reduced performance and premature failure.
What is the difference between the B.O.S. and the RealPRO Series charger?
The RealPRO Series charger is responsible for delivering the electrical current to charge the batteries, providing 12A total output across two 6A banks. The B.O.S. system works in conjunction with the charger, managing and optimizing the charge distribution between batteries to ensure they remain balanced, thereby enhancing overall battery health and lifespan.
Can this charger be used with different battery chemistries like AGM?
Yes, this Dual Pro RS2 charger with the B.O.S. system is approved for use with both traditional Wet Cell batteries and Absorbed Glass Mat (AGM) batteries, offering versatility for various marine electrical system configurations.
What is the warranty period for the Dual Pro RS2 charger?
The Dual Pro RS2 charger comes with a comprehensive two-year warranty, providing assurance of its durability and performance in demanding marine environments.
Is this charger ignition protected for marine use?
Absolutely. This charger is ignition protected, meeting US Coast Guard safety standards (33 CFR 183.410), which is critical for safe operation in gasoline-powered vessels and environments where flammable vapors may be present.
