Common Concerns Answered
Is the B.O.S. system difficult to set up?
While some users report a slight initial complexity in understanding the B.O.S. system, the overall installation is straightforward. The manual provides detailed guidance, and the system is designed to integrate seamlessly with your existing battery setup.
Is 6A per bank sufficient for my batteries?
The 6A per bank is ideal for maintaining optimal charge and extending battery life, particularly with the B.O.S. balancing active. While not intended for extremely rapid charging of very large banks, it is highly effective for standard charging cycles and battery health maintenance.
Is this charger a good investment if I haven't had battery issues before?
The Dual Pro RS2 with B.O.S. offers proactive battery health management, preventing future issues related to imbalance. By actively balancing batteries in series, it significantly extends their lifespan and optimizes performance, offering long-term value beyond reactive charging.
Frequently Asked Questions
What is the B.O.S. Battery Optimization System and how does it work?
The B.O.S. (Battery Optimization System) actively monitors and balances the voltage across multiple batteries connected in series. It accomplishes this by intelligently shuttling energy between batteries to ensure they maintain uniform charge levels, thereby preventing premature failure caused by individual battery strain.
What is the difference between the B.O.S. and the RealPRO Series charger?
The RealPRO Series charger (RS2) is responsible for delivering the charging current to the battery banks, providing 12A total output. The B.O.S. is a separate, complementary system that works in conjunction with the charger to actively manage and balance the voltage of batteries within a series connection, ensuring optimal charge distribution.
Can this charger be used with different battery chemistries like AGM?
Yes, the Dual Pro RS2 charger is approved for use with both traditional Wet Cell batteries and Absorbed Glass Mat (AGM) batteries. The B.O.S. system is also compatible with any battery chemistry.
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 reliability and performance.
Is this charger ignition protected for marine use?
Yes, this charger is ignition protected according to US Coast Guard standards (33 CFR 183.410), making it safe for use in potentially flammable marine environments.
