Common Concerns Answered
Why is this charger more expensive than basic models?
The higher price reflects the advanced integration of Dual Pro's Battery Optimization System (B.O.S.) which actively manages battery health in series configurations, alongside the multi-chemistry charging capabilities (Lithium/AGM) and robust marine-grade construction. This system is designed for significantly extended battery life and performance, offering a long-term value proposition.
Is the B.O.S. system complicated to set up?
The B.O.S. system requires correct series wiring of your battery bank, which is a moderate installation step. While the charger itself is plug-and-play, understanding how the B.O.S. intelligently balances voltages may require a brief review of the manual, but users consistently report that the benefits in battery longevity outweigh any initial learning curve.
Will this charger fit my existing battery setup?
This charger is designed for marine applications and specifically for boats utilizing multiple batteries in series for trolling motors or other high-draw systems. It is compatible with both Lithium and AGM chemistries, offering flexibility. The B.O.S. system's effectiveness is optimized for batteries wired in series.
Frequently Asked Questions
What is the B.O.S. (Battery Optimization System) and how does it work?
The B.O.S. is an active battery balancing system that monitors individual battery voltages within a series bank. It intelligently shuttles energy between batteries using a BSAP-24 algorithm, ensuring all batteries maintain equal voltage. This prevents individual batteries from being over-discharged or over-charged, thereby extending the overall lifespan and performance of the battery bank.
Can this charger charge both Lithium and AGM batteries?
Yes, the SS4 Auto charger is specifically designed to automatically detect and optimally charge both Lithium (LiFePO4) and AGM (Absorbed Glass Mat) battery chemistries.
What is the amperage output per bank for the SS4 Auto charger?
The SS4 Auto charger provides an independent output of 10 Amps per bank, for a total output of 40 Amps across the four banks.
Is this charger waterproof?
Yes, the Dual Pro SS4 Auto charger features a waterproof design, essential for harsh marine environments.
How does the B.O.S. system improve battery life and performance?
By actively balancing the voltage across batteries in series, the B.O.S. system prevents premature failure of individual batteries that might otherwise be overstressed. This equalization ensures that the entire battery bank performs more consistently and achieves its maximum potential run time, significantly extending overall battery longevity.
