(Battery Optimization System) - 12V - 3-Bank (PN: BOS12V3) and Dual Pro&';s Sportsman Series Battery Charger - 40A - 4-10A-Banks - 12V-48V (PN: SS4).B.O.S. (Battery Optimization System) - 12V - 3-BankB.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.
