Description
Dual Pro SS2 2 Bank Battery Charger w/BOS | Boat Supply Store
Maintain peak battery performance and drastically extend service life in multi-battery configurations with this integrated charging and optimization system. The Dual Pro SS2 charger provides a robust 10A output to each of its two banks, supporting 12V/24V operation and multi-stage charging for Wet Cell and AGM chemistries. Its core innovation is the proprietary B.O.S. (Battery Optimization System) utilizing a BSAP-24 algorithm to actively shuttle energy, maintaining equal voltage across series-wired batteries and effectively quadrupling on-water run time by preventing premature degradation.

Common Concerns Answered
Why is this charger more expensive than basic models?
The higher initial cost reflects the integration of Dual Pro's advanced B.O.S. Battery Optimization System, which actively manages and balances battery packs. This proprietary technology significantly extends battery life and improves on-water performance, leading to substantial long-term cost savings by reducing premature battery replacement.
Is installation complicated?
Installation is rated at a 3/5 difficulty, requiring basic electrical knowledge. While the charger unit is typically mounted on-board, the B.O.S. system adds a few straightforward connections between batteries, which are clearly detailed in the provided manual.
Does the B.O.S. system drain power when not actively charging?
No, the B.O.S. system operates with an exceptionally low sleep mode draw of less than 1mA, ensuring minimal impact on battery standby power when not actively engaged in charging or balancing.
Frequently Asked Questions
How does the Dual Pro B.O.S. system improve battery life?
The B.O.S. system uses a proprietary BSAP-24 algorithm to shuttle energy between batteries wired in series. This process actively maintains equal voltage across the battery pack, preventing individual batteries from becoming overcharged or undercharged, which is a primary cause of premature failure in multi-battery systems and significantly extends overall battery longevity.
What is the charging output for each bank on the Dual Pro SS2 charger?
The Dual Pro SS2 charger provides a dedicated 10A charging output for each of its two banks, offering a total combined output of 20A.
Is the Dual Pro SS2 charger waterproof and suitable for saltwater use?
Yes, the Dual Pro SS2 charger features a waterproof, rugged construction specifically designed for reliable operation in both fresh and saltwater marine environments.
Can the Dual Pro SS2 charger be used with different battery chemistries like AGM or Gel?
The Dual Pro SS2 charger is approved for use with Wet Cell and AGM batteries. It is not specified for Gel batteries.
What is the power consumption of the Dual Pro B.O.S. system in sleep mode?
In sleep mode, the Dual Pro B.O.S. system consumes less than 1mA of power, ensuring minimal drain on the batteries when not actively engaged.
