Description
Dual Pro RS3 3 Bank Charger w/BOS | Boat Supply Store
For anglers running multiple trolling motor batteries offshore, this system prevents premature failure and quadruples run time by actively balancing battery packs. The RealPRO Series charger provides independent outputs at 18A each, with automatic charging and maintenance modes. The integrated B.O.S. (Battery Optimization System) utilizes a BSAP-24 algorithm to shuttle energy between batteries wired in series, maintaining equal voltage and improving overall performance and longevity for up to six batteries.

Common Concerns Answered
The initial cost is higher than standard chargers; is it worth the investment?
The Dual Pro RS3 with B.O.S. represents a significant upgrade over standard charging systems. Customers consistently report quadrupled battery run times and extended battery life, making it a cost-effective solution over time by preventing premature battery replacement and ensuring reliable performance.
I'm concerned about the complexity of the B.O.S. system's wiring.
While the B.O.S. system has specific wiring requirements for series connections, the manual provides detailed instructions. For those unfamiliar with marine electrical systems, professional installation is recommended to ensure proper setup and optimal performance.
The AC power cord is only 3ft long; is this sufficient for most installations?
The 3ft AC power cord may require an extension cord depending on your specific installation location. It is designed for direct proximity to an AC power source, and users often integrate longer extension cords as needed for optimal placement within their vessel.
Frequently Asked Questions
What is the B.O.S. (Battery Optimization System) and how does it work?
The B.O.S. actively monitors and balances voltage across batteries wired in series. It intelligently shuttles energy between them using the BSAP-24 algorithm to ensure all batteries maintain an equal charge state, preventing overcharging of one battery and undercharging of another, thereby enhancing overall pack performance and longevity.
What is the amperage output per bank for the RealPRO Series charger?
The Dual Pro RS3 charger provides an 18A total output, distributed independently across its three banks, resulting in a 6A output per bank.
Can this charger be used with different battery chemistries like AGM?
Yes, this charger is approved for use with both Wet Cell and Absorbed Glass Mat (AGM) batteries, offering versatility for various marine applications.
What is the warranty period for the Dual Pro RS3 charger?
The Dual Pro RS3 charger comes with a two-year warranty, providing confidence in its durability and performance.
Is this charger ignition protected for marine use?
Yes, this charger is ignition protected, meeting US Coast Guard 33 CFR 183.410 standards, which is crucial for safety in potentially hazardous marine environments.
