Product Overview

RS3 3 Bank Battery Charger with B.O.S. Technology

This kit includes Dual Pro's B.O.S. (Battery Optimization System) and Dual Pro's RealPRO Series Battery Charger, designed to efficiently manage and extend the life of your batteries.

B.O.S. (Battery Optimization System)

The B.O.S. actively redistributes energy between batteries to maintain balance, enhancing battery strength and longevity. In applications where multiple batteries are interconnected, it is vital to ensure they remain balanced to maximize performance and lifespan.

B.O.S. facilitates energy transfer among batteries in series, ensuring equal voltage during charging and run time, effectively doubling your operational duration without premature battery failures typically associated with mismatched power levels.

The innovative BSAP-24 algorithm predicts which battery requires additional charge, systematically prolonging each battery's life and improving overall pack performance.
