PS3 3 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 Professional Series Battery Charger - 45A - 3-15A-Banks - 12V-36V (PN: PS3).

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
  • Battery Selection and Prediction (BSAP-24) algorithm
  • Less than 1mA sleep mode
  • Transfer rate up to 7.5A
  • Self-powered
  • Any type of battery chemistry

Used in Any Application Where Batteries Are in Series:

  • Marine
  • Golf
  • Industrial
  • Aerial Equipment
  • Solar Power
  • Electrical Vehicles
  • Communications
  • Defense/Military

Dual Pro PS3/BOS12V2 Battery Charger and Battery Optimization System Kit combines a 45A Professional Series battery charger with a 12V two-bank B.O.S. Battery Optimization System. Designed for series-connected battery packs, this kit helps boaters, anglers, and equipment operators maintain balanced batteries while supporting dependable charging in marine, golf, utility, and other recreational applications.


The B.O.S. actively shuttles energy between batteries as needed to help equalize voltage before, during, and after charging. Its Battery Selection and Prediction (BSAP-24) algorithm identifies which battery needs additional energy, helping the battery pack operate as a more balanced system. This is especially useful in watercraft where trolling motor batteries may also power accessories or assist the cranking battery.


The Dual Pro Professional Series charger delivers 45 amps through three independent 15A banks and is designed for 12V to 36V battery systems. DeltaVolt intuitive charging technology, fully automatic multi-stage charging, battery maintenance mode, temperature compensation, and LED charge-status indicators help simplify routine battery care. Waterproof construction, reverse-polarity protection, zero-spark technology, and ignition protection support use in fresh and salt water environments when installed according to applicable requirements.


Key Features:

  • Integrated battery management: Combines the PS3 charger and BOS12V2 system for charging and balancing series-connected battery packs.
  • 45A three-bank charging: Provides three independent 15A outputs for 12V to 36V battery systems.
  • Active battery balancing: Transfers energy between batteries to help maintain equal voltage across the pack.
  • Automatic charging control: Uses multi-stage charging, maintenance mode, temperature compensation, and LED indicators.
  • Marine-ready construction: Designed for fresh and saltwater use with waterproof construction and ignition protection.

Product Details:

  • Brand: Dual Pro
  • Part number: PS3/BOS12V2
  • Charger: Professional Series, 45A, three 15A banks
  • Battery system: 12V to 36V
