SS4 Auto 4 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 SS4 Auto 40A - 4-Bank Lithium/AGM Battery Charger (PN: SS4AUTO).

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

Would buy again and again
Color: Black, Size: 35.4 Inches
These are beautiful! I thought they’d be hard to install, but very straightforward and easy. They are quality and sturdy. I staggered the shelves and they hold a lot. Great value for the quality. I will be buying more for another room in the house.

Color: White, Size: 15.7 Inches
The mounting and the color were excellent. I hung this in my bathroom and thought it was going to be a hard install for me. The hardware that came with this was very self explanatory. The fit was perfect and the quality was great. I would surely buy this item again in the future

Floating Shelves
Color: White, Size: 15.7 Inches, Color: White, Size: 15.7 Inches
I purchased a set of white floating shelves for my bedroom a couple months back, and I must say, they have definitely added a touch of modern elegance to the space. The installation process was surprisingly simple and straightforward, making it a breeze to set up the shelves exactly where I wanted them. The package came with all the necessary hardware, including sturdy brackets and screws, ensuring a hassle-free setup experience. I will say that the wall anchors included are not the best quality and I used a third party set. The sleek and minimalistic design of these floating shelves instantly caught my eye, and I couldn't be happier with how they complement the overall decor of my room. The clean lines and the bright white finish pop with the walls, providing a chic and uncluttered display area for my decorative items, and cherished keepsakes. They truly elevate the aesthetic appeal of any room and create an illusion of more space, which is always a bonus. However, one aspect that did disappoint me slightly was the visibility of the screws underneath the shelves. While the overall appearance is sleek and sophisticated, this minor flaw hinders the shelves from achieving a truly seamless "floating" effect. I understand that the screws are essential for stability and security, but I wish the manufacturer had found a way to conceal them better, perhaps with a cleverly designed cover or by providing white screw caps. Despite this minor setback, I still appreciate the functionality and attractiveness of these floating shelves. They have undoubtedly decluttered my living space and allowed me to proudly showcase my favorite items. I have received compliments from friends and family on how the shelves enhance the ambiance of the room. In conclusion, if you are seeking easy-to-install, stylish white floating shelves to add a contemporary touch to your home, these shelves are an excellent choice. Their seamless installation and sleek appearance make them a delightful addition to any room. Although the visible screws detract slightly from the overall aesthetic, the shelves' overall performance and elegance more than make up for it.

Good Product
Color: White, Size: 15.7 Inches
Well designed and sturdy. Though not real wood I think they will last. It took me an hour to install the first shelf. That was all on me. I was slow measuring and placing the shelf bracket. I kept dropping the level and doing other crazy things. But the second and third shelves were easy after I learned what I was doing. Even though the screws, etc were provided I used Easy Anchor drywall anchors rated at 50 pounds. Just drill it in the sheet rock then screw the screw through the hole in the bracket until it clicks, (you have to listen). That means the ends of the plastic anchor flips out like a toggle bolt. Continue tightening the screw and that is it. Think I read somewhere that the board wobbles. These were tight as could be and no wobble. I did learn to only "tighten" just one end of the bracket sort of snug and let it hang. Then raise it to level and mark the other holes with a pencil. Don't put the other screws in until you are sure you can see the plastic anchors' holes though the bracket. Then place and tighten all the screws. The only negative I saw was that they could have sent the same or similar anchors that I have. But they didn't call me. Guess they didn't have my number.
