Dual Pro SS4 Auto 4-Bank Battery Charger with 2-Bank B.O.S. for Marine, Lithium, and AGM Batteries

SS4 Auto 4 Bank Battery Charger with 2 Bank B.O.S.

This kit includes Dual Pros B.O.S. Battery Optimization System - 12V - 2-Bank (PN: BOS12V2) and Dual Pros SS4 Auto 40A - 4-Bank Lithium/AGM Battery Charger (PN: SS4AUTO).

B.O.S. Battery Optimization System - 12V - 2-Bank

B.O.S. actively shuttles energy between batteries to keep the pack balanced, increasing battery strength and longevity.

Batteries in a pack will become out of balance and the pack is only as good as its weakest link. In watercraft applications, this is further compounded when the trolling motor battery is used for peripherals and/or to assist the cranking battery.

B.O.S. actively shuttles energy as needed between batteries wired in series to ensure equal voltage before, during, and after charging.

B.O.S. keeps packs balanced, enabling maximum performance, and quadruple run time on the water.

Premature battery failure due to an unbalanced pack has been, unfortunately, accepted as the norm for decades. The B.O.S. answers this call with a BSAP-24 algorithm that can accurately predict and select the battery that needs additional energy to match the other batteries within the pack. This simultaneously and successfully extends the life of each battery in the pack, as well as increasing run times.

Features:

• Available in 6V, 8V, and 12V configuration
• Up to six batteries in a series

AutoProfile Intuitive Charging Technology Lithium/AGM

Professional and Sportsman Series chargers have set the standard in the marine industry for more than two decades, known as the safest, most reliable, and best performing chargers in the industry.

AutoProfile Intuitive Charging Technology provides flexibility for the charging system, ready for the ever-changing lithium battery technologies. No matter if users choose Lithium or AGM batteries for the boat, Dual Pro is ready to keep a boat on the water longer, enhancing battery performance and extending battery life.

The Dual Pro SS4 Auto 4-Bank Battery Charger with integrated 2-Bank B.O.S. (Battery Optimization System) offers a comprehensive solution for maintaining and extending the performance of multiple batteries in series configurations. Designed for marine, industrial, and recreational applications, this system ensures your batteries are balanced, healthy, and ready for peak performance. The B.O.S. actively shuttles energy between batteries to keep the pack balanced, which helps prevent premature battery failure and maximizes runtime on the water or in other demanding environments. This technology is particularly beneficial when batteries are used for multiple functions, such as trolling, cranking, or powering peripherals, where imbalance can significantly reduce overall battery life and performance.
