Dual Pro is known for producing durable and repairable marine electronics. While availability of parts for very old models can sometimes be a consideration, the SS4 series is designed for longevity and serviceability, ensuring support for its advanced features and robust construction.
Frequently Asked Questions
What is the B.O.S. (Battery Optimization System) and how does it function?
The Battery Optimization System (B.O.S.) is Dual Pro's proprietary technology designed to actively balance voltage across multiple batteries wired in series. It monitors individual battery voltages and intelligently shuttles energy between them to ensure all batteries in the bank maintain an equal charge level, preventing overcharging or undercharging of any single battery and thereby maximizing overall system health and lifespan.
What is the specific charging output for each bank on the Sportsman Series charger?
Each of the four charging banks on the Dual Pro SS4 Sportsman Series charger provides an independent output of 10 Amperes (10A).
Is this charger compatible with both wet cell and AGM batteries?
Yes, the Dual Pro SS4/BOS12V3 is approved for use with both traditional wet cell batteries and absorbed glass mat (AGM) batteries.
Can this charger be safely operated in saltwater environments?
Absolutely. This charger is designed and tested for use in both fresh and saltwater marine environments, featuring rugged, waterproof construction to withstand harsh conditions.
What is the maximum battery system voltage this charger can support?
The Dual Pro SS4/BOS12V3 is engineered to support battery systems ranging from 12 Volts up to 48 Volts.
