RS4 4 Bank Battery Charger with 2 Bank B.O.S.

This kit includes Dual Pro’s B.O.S. Battery Optimization System - 12V - 2-Bank (PN: BOS12V2) and Dual Pro’s RealPRO Series Battery Charger - 24A - 4-Bank (PN: RS4).

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

Beautifully Made and Worth the Cost!
Color: XY010-Silver
It's beautiful, sturdy and able to hold quite a few chains, rings, earrings, bracelets all in one place without them tangling up. Also, because it's so neat, it doesn't take up much space. I'm very happy with it!

beautiful
Color: XY010-Silver
Purchased for granddaughter to keep in her bathroom. She normally removes jewelry and leaves on sink. A $40 bracelet was lost into the waste basket so this will prevent that. Came flat so I gently bent the branches and it is now a 3 dimensional tree . Beautiful.

Awesome -- they work perfectly
Style: Updated 3.46in Magnet L Red Hooks 2PCS
Got these to store a DeWalt cordless drill and impact driver on the side of a Gladiator garage cabinet -- and they work perfectly for that. The magnet is incredibly strong, easily supporting the bare tools, and seems even to work perfectly well with an 8ah XR battery on the tool -- not that it's necessary since I don't store them like that. I like that the magnet is padded with rubber. Very nice units, I will get more for sure to store other items.
