SS3 3 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 Sportsman Series Battery Charger - 30A - 3-10A-Banks - 12V-36V (PN: SS3).

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

Not chew proof for little puppies
Color: Rings, Size: Small
Our first Chihuahua when she was a puppy loved chewing on this and pieces never came off. Our second Chihuahua I guess was a heavier tour and he was able to get pieces flaked off.

Great for teething puppy
Color: Pacifier, Size: Small
I was trying to find something very sturdy for our puppy that she could not bite pieces off of and this toy has been great. She loves it and it has held up very nicely. They are not soft so it is great for our teething pup. They are also the perfect size if you have a bigger pup like we do. She is a 4 month old pit mix. I would say they would be too big for a small breed puppy

Good size ball for my big boy
Color: Purple
My big boy loves this ball. He chews and chews and chews on it and it ain't made a dent in it. It's made a good quality rubber. It's got a squeaker in it. He hasn't managed to get it out which is not normal because normally he can get a squeaky out within 10 minutes. He goes through toys like I don't know what so it's being being a good. Really good ball. We've had it for about 2-3 months now and he hasn't been able to break into it and get squeaky out or even make a dent into it. That would tear up the the rubber

Sturdy ball, holding up well.
Color: Purple
I have a ball obsessed Shih Tzu. This has become his security blanket. He literally takes it everywhere and even sleeps with it next to him. Dexter loves any ball. All shapes and sizes. He will play fetch all day long if you let him. He doesn't know when to quit. It can be 100 degrees out with 80% humidity and he'll fetch all day long. This is a larger ball, I think just over 3 inches. It is entirely too big for a Shih Tzu, but it is perfect for Dexter. He came to us with a ball similar to this that he has since lost. He carries it in his mouth by placing his incisors in the indentations and lets it hang out the side of his mouth. Quite comical actually, but it works for him. We have bought him balls more for his size, but they're too small and he gets them lost under cabinets, furniture or any nook and cranny the ball will fit. And being obsessive, he will bark and carry on because he can't get to the ball until you come and rescue it. Difficult on our old knees. So he ends up getting the smaller balls taken away from him. The other night he was laying and chewing on this ball. It sounded like he was shredding this ball to pieces. I was afraid he would choke or swallow the rubber pieces, so I took it away from him. There wasn't anything wrong with the ball. It looked brand new. No chew or bite marks that I could see. I was impressed. It does have a squeaker, but I can barely get it to squeak and I have strong hands. A larger dog with a stronger bite force could probably easily make it squeak. It claims to have a beef scent to the toy, and maybe that is why he likes the ball so much. But I sniffed it and couldn't smell anything, which is fine by me, it won't have an obnoxious smell to where I don't want it around me.

Dogs love balls
Color: Orange
Most dogs love to play with balls. This is a ball. It squeaks and can handle a lot of strong chewing. Quite durable and a good size for medium and up sized dogs. (Honestly even smaller dogs would have fun with this).
