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.

Features:

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

It really cools - Extremely soft - Not too heavy
Size: Queen (90" * 90"）, Color: Luxury Grey, Size: Queen (90" * 90"）, Color: Luxury Grey
This comforter arrived packaged very well from the manufacturer. It arrived sealed in plastic inside a box. The color and appearance of the comforter received looks like what was shown in the listing. This comforter is extremely soft. It feels very cool to the touch. It has a great cooling effect. It is also not too heavy. A lot of cooling bedding products like this feel heavy. While this does have some weight it is not too much. It is easy to move around. The comforter is easy to refresh and cool off again after extended use. I just uncovered myself, lifted and moved the comforter around a little, then covered back up. This made it feel cooler again. I am very happy with this comforter so far. I like the color and design. I really like feeling cool when falling asleep. This will be great when the temperatures start going up. I will update this review later if anything changes after washing a few more times and longer use. I think this will be a good comforter for most hot sleepers who like to cover up all year.

Feels seriously amazing!
Size: Twin（90“ * 67”）, Color: Luxury Grey
This is my second cooling comforter from this brand and this one is just as amazing as the first. It’s silky soft and makes a significant temperature difference. It’s like magic; you don’t need to do anything special to cool it before bed. If you do want extra coolness, you can place it in front of your AC or turn on your fan for a little bit before bed and It absorbs the extra coolness but either way it lasts all night. I use it with the cooling pillow, and the hot summer nights are no match. It’s easy to wash, really silky, smooth, and actually cool against the skin. It also somehow has a weighted blanket-like feel without being heavy. I standby this blanket so much that this is my second one, highly recommend!

Super Soft, Lightweight, and Surprisingly Cozy
This ended up being so much better than I expected. The first thing I noticed is how incredibly soft it is - it has that plush, velvety feel that makes you want to keep reaching for it all day. It’s lightweight but still warm, which I really like. It gives you that cozy, wrapped-up feeling without being heavy or overwhelming, so it works well for everyday use on the couch or even for sleeping. For reference, I’m 5’2” and it’s big enough to comfortably use as a full snuggle blanket. It also looks really nice draped over furniture. The texture adds a little dimension, and the clean, simple color gives it a polished look that doesn’t feel cheap. One thing to note is that it arrives compressed, but it fluffs up nicely once opened and feels much fuller after a little time. The only thing to keep in mind is that lighter colors will naturally show dirt more easily, so that’s something to be aware of with regular use. Overall, this has easily become my go-to daily throw - soft, comfortable, and much nicer than I expected for the price.

luxury fleece throw blanket ribbed plush texture cozy aesthetic blanket
This is one of those blankets that instantly makes a space feel more cozy and put together. The first thing that stands out is the texture. It has that plush, ribbed look that’s been really popular lately, very similar to those oversized lounge chairs and couches with the same soft, fluffy pattern. It looks especially good draped over furniture and adds a nice aesthetic touch instead of just being functional. It’s also genuinely soft and comfortable. The fleece has that “cloud-like” feel without being heavy or stiff, and it’s warm enough for everyday use without feeling overly thick. The size at 50 x 60 inches is great for lounging, whether you’re watching TV or just relaxing. I really appreciated how it was packaged. Instead of being secured with a bunch of plastic fasteners, it was simply wrapped with a ribbon, which made it easy to open and avoided the usual hassle of cutting out plastic tags. It also arrived vacuum sealed and had no odor at all, so it was ready to use right away. They even included a full-color instruction card, which was honestly a nice touch. It goes over care and even styling ideas, which adds to the overall presentation and makes it feel more polished. For the price, this feels like a great value. It looks good, feels good, and works well both as a functional blanket and as part of your home decor.

Good value, packed nice and small for travel or gifting, fluffs up thick
I ordered this throw - which, by the way, is OEKO-tex and CERTipur rated - because I don't have a white, fluffy throw in my otherwise cream and tan colored house. It arrived vacuum sealed and wrapped with a bow in a miniscule bag measuring 2" x 8" by 8". If you want to travel, say on a cruise ship or on a vacation for a week, and bring a comfort item, this is for you. It's so small that it won't take up hardly any room in your suitcase, but once you arrive at your destination, wow. It expands and fluffs up beautifully. It's super soft and really thick and comfy. It washes and dries very well. (On a cruise ship you could wash in the shower and wring, then hang to dry - it would probably dry overnight, or faster out on the balcony). I tried to get a close-up of the fluffiness but my camera wouldn't cooperate. At $15.99 it's competitively priced and comes with the added bonus of being vacuum sealed. Also has a instruction booklet for keeping the throw looking its best. Highly recommended.
