PS4 Auto 4 Bank Battery Charger with 3 Bank B.O.S.

This kit includes Dual Pro’s B.O.S. Battery Optimization System - 12V - 3-Bank (PN: BOS12V3) and Dual Pro’s PS4 Auto 15A - 4-Bank Lithium/AGM Battery Charger (PN: PS4AUTO).

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

must-try. Five stars from me!
Size: 4.2 Fl Oz (Pack of 1)
I recently tried the **ELBBUB Whipped Tallow Cream**, and I can confidently say it's one of the best skincare products I've ever used! From the moment I opened the jar, I was struck by the light, fluffy texture that feels luxurious and indulgent. This cream absorbs beautifully into the skin, leaving it feeling incredibly soft and hydrated without any greasy residue. It’s perfect for daily use and works wonders on dry areas, especially during colder months. My skin feels plump and nourished, and I've noticed a significant improvement in its overall texture and appearance. The ingredients are clean and wholesome, giving me peace of mind about what I'm putting on my skin. I also appreciate the subtle, natural scent that isn’t overpowering, making it suitable for anyone sensitive to strong fragrances. What truly sets this cream apart is its versatility. I’ve used it on my face, hands, and even as a body moisturizer, and it performs flawlessly across the board. It's become an essential part of my skincare routine, and I can’t recommend it enough! If you’re looking for a rich, effective moisturizer that truly delivers, the ELBBUB Whipped Tallow Cream is a must-try. Five stars from me!

So soft I love!!
Size: 4.2 Fl Oz (Pack of 1)
I have been using this tallow cream for months now and my skill feels so moisturized every time I use it. I have had it for a while and still have half of the jar left so, a little does really go a long way. I really wanted to switch to a natural product to avoid putting harsh/unnecessary chemicals on my face. I also have pretty dry skin which was another big reason why I wanted to try tallow for my face. It is fragrance free which is I do like. I have not noticed much of a change in my skin appearance, largely because I do already have good skin but I love the way it makes my face feel. I did not notice any major breakouts when I started using this product, though I have never had sensitive skin. My boyfriend does have sensitive skin though and he uses it from time to time and has never complained about breakouts. I think this product is worth trying, though everybody's skin is different so you just have to test it out and see!

Highly recommend
Size: 4.2 Fl Oz (Pack of 1)
This is a great product. I’ve probably ordered at least 10 jars at this point. I use it as my every day facial moisturizer. It’s not greasy, I’ve had no break outs, it has virtually no smell, and I love that there are no random unnecessary ingredients added. My husband (who has very sensitive skin) now also uses it as his dairy facial moisturizer. Highly recommend!

Very thick, rich cream. Good for hands or overnight.
Size: 4.2 Fl Oz (Pack of 1)
I like this, but I don't love it. It's very rich and creamy, no discernible scent, and feels good going on. The beeswax in this makes it a good "barrier cream", great for overnight. This is very moisturizing, but it does not seem to penetrate as deeply as another tallow cream that I tried which has no beeswax. It's a nice sized jar for the price. This is really good for hands. I'm still on the hunt for a really good tallow cream that doesn't contain wax or olive oil...the search continues.

Non-greasy
Size: 4.2 Fl Oz (Pack of 1)
Very smooth and non-greasy. Helped my cracked heels in about three weeks! I use it on my face and haven't had any issues with break-outs or oily skin. Nice product, worth the money. I have bought twice and will again.
