SS3 Auto 3 Bank Battery Charger with 3 Bank B.O.S.

This kit combines Dual Pro’s B.O.S. Battery Optimization System - 12V - 3-Bank (PN: BOS12V3) and Dual Pro’s SS3 Auto 30A - 3-Bank Lithium/AGM Battery Charger (PN: SS3AUTO).

B.O.S. (Battery Optimization System) - 12V - 3-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.

  • Available in 6V, 8V, and 12V configuration
  • Up to six batteries in a series
  • Battery Selection and Prediction (BSAP-24) algorithm

Perfect Sink Organizer — Compact, Sturdy, and Stylish
Color: Black
This large sponge holder for the kitchen sink is exactly what I needed to clean up my countertop clutter. The 90-degree L-shaped design fits perfectly into the corner by the sink, making great use of space without getting in the way. The metal construction feels solid and durable, and it holds everything neatly—sponges, soap, and a dish brush all in one place. I especially like that it allows items to drain and dry properly, which helps keep things cleaner and more hygienic. Setup was quick and simple, and the minimalist design looks great with modern kitchen décor. It stays stable, doesn’t tip over, and keeps essentials easily within reach. Overall, this sink caddy is a smart, practical storage solution that’s both functional and attractive. A small upgrade that makes a big difference—highly recommended!

Sponge Holder
Size: 7.125 x 2.875, Color: Black, Size: 7.125 x 2.875, Color: Black
This sponge holder is a simple upgrade that makes a big difference in keeping the sink area clean and organized. The suction cup holds firmly to the side of the sink, so it doesn’t slide around or fall off like cheaper options. It easily fits both a sponge and a steel scrubber, keeping them elevated and allowing them to dry quickly, which helps prevent odors and bacteria buildup. The open wire design is especially useful because it allows water to drain instead of pooling at the bottom. Installation is quick and requires no tools—just press it onto a clean surface and you’re good to go. It also keeps the countertop clutter-free, which is a nice bonus. Overall, it’s durable, functional, and does exactly what it’s supposed to do. Great value for anyone looking to keep their kitchen sink area tidy and hygienic.
