SS2 2 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 Sportsman Series Battery Charger - 20A - 2-10A-Banks - 12V/24V (PN: SS2).

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

Used in Any Application Where Batteries Are in Series:

  • Marine
  • Golf

  • Aerial Equipment
  • Solar Power
  • Electrical Vehicles

Easy to assemble but overpriced for what you get
I like this rack. Especially because it was very easy to assemble. Although it is only suitable for one size spice bottles. It wont hold larger or taller spices which was a small issue for me. But overall i found it good quality. But i think the price is a bit overpriced for what you receive and for the functionality

Excellent way to store spices
In the description it clearly states only 4 oz spice jars are recommended, so keep that in mind when ordering. I also included in my pictures one of their pictures showing the size recommendation for your cabinet, that way you can check that too before ordering. Doing both of these things will provide a happier buying experience and minimize frustration with the product itself. I already had a tiered spice rack that fit my larger and bulk spices beautifully. I felt having my larger spices with my smaller spices made it difficult to access certain items and it just felt chaotic. To solve that issue I order this spice rack organizer for the smaller spices. It was super easy to assemble. All hardware is included and in addition to the hardware to put this together they also included screws, that way if you would like to screw the spice rack into the cupboard itself you can. I did not choose to screw the spice rack down. I have had no issues with it moving around when I use the pull out. It pulls in and out smoothly and with barely any effort. The pull out design I feel maximizes space and allows you to see everything all the way to back of the rack. This rack is great for any size space and holds a lot of spices. I had additional room to more spices that I did not need even after adding all the small spices that would fit into each of the pull outs. I feel the price reflects the quality of the product. Yes it is a steep price and can be viewed as expensive, on the other side you get what you paid for. It is aesthetically pleasing and I am planning on at some point buying spice jars that you fill yourself to use on this spice rack. Eventually I am hoping to be more organized and even have my bulk spices be placed in the individual jars that I fill myself while keeping the bulk container in my pantry. I am extremely pleased with this heavy duty spice rack and do recommend it to others.

Sturdy, Space-Saving Organizer That Makes Cabinets Way More Functional
The **BOIVSHI 2-Tier Vertical Pull-Out Spice Rack Organizer** is a really practical upgrade if you’re trying to clean up a cluttered cabinet or pantry. The vertical design makes excellent use of narrow spaces, and the **smooth sliding rails** are one of the best parts—it pulls out cleanly so you can actually see everything instead of digging through shelves. The metal frame feels solid and heavy-duty, and the chrome finish gives it a clean, modern look that blends well inside most cabinets. It’s especially helpful for organizing spice jars, oils, sauces, or small pantry items so everything stays upright and easy to grab. Installation is fairly simple, and once mounted, it feels stable when sliding in and out. The motion is smooth enough that it doesn’t feel like it’s going to jam or tip items over, which is a common issue with cheaper pull-out racks. One thing to keep in mind is sizing—this type of organizer works best in **standard-width cabinets**, so measuring your space first is important. Also, like most pull-out systems, it’s more about **function and accessibility** than maximizing sheer storage volume. Overall, it’s a very effective way to turn wasted cabinet space into organized, accessible storage. If you’re tired of stacked spice jars or cluttered shelves, this is a strong upgrade.

A Sturdy Spice Rack With Some Perks and Some Limitations
We really needed a new spice rack that holds a variety of bottle sizes, and this one is made for a pretty brand-specific bottle style. It does hold some of the older model metal containers, so it looks like we will be adapting to the newer sizes and shapes. This organizer is easy to assemble and fits the space I designed perfectly. The bottom shelf is very sturdy, and the top shelf is not quite as solid, and I'm not sure exactly why. One thing is for sure: when you fill this spice rack to capacity, you will have all the spices necessary for a well-stocked kitchen. We have not filled it up, but my guess is that we can fit between 35 and 40 individual spice bottles and cans. Overall, it is at the higher end of value for the money, but it may serve us perfectly through the years and prove itself to be an excellent value and keep all of our spices well organized.
