RS4 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 RealPRO Series Battery Charger - 24A - 4-Bank (PN: RS4).

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
  • Less than 1mA sleep mode
  • Transfer rate up to 7.5A
  • Self-powered
  • Any type of battery chemistry

Used in Any Application Where Batteries Are in Series:

  • Marine
  • Golf
  • Industrial
  • Aerial Equipment
  • Solar Power
  • Electrical Vehicles
  • Communications
  • Defense/Military

So soft, nice padding, & color perfect for a dog’s bed
Color: Beige, Size: 41" x 27"x 4", Color: Beige, Size: 41" x 27"x 4"
Of course, this dog bed came lumpy, but once you roll it out and manipulate it it lays perfect. My dog Loki outgrew the little one that we had but this one is perfect. He’s 55 pounds and I would say it’s even a little bit big for him. We will definitely keep it though. It’s so soft and pretty and Loki will not leave it so it’s a win-win.

Great Pet Beds!
Color: Grey, Size: 41" x 27"x 4"
These dog beds are wonderful! I have two large dogs (65-70 lbs) who lay on them daily. They’ve maintained their shape and thickness. The size is perfect, and they’re easy to spot clean. I definitely recommend them, especially if using in a carpeted room. Great value!

Single greatest thing I’ve ever bought for my dogs
Color: Charcoal, Size: 35" x 23"x 3.5", Color: Charcoal, Size: 35" x 23"x 3.5"
Few years ago we got our dog a dog. It was a bad idea. Our first dog is incredibly smart. He’d much rather hang out with humans, sitting in his own chair at the table while we play board games and chat than chase a ball. He uses talking buttons and picked it up quickly. Even as a little puppy he was kind of serious and when we’d take him to the dog park he’d mostly just run around barking at other dogs who were having too much fun. Then came his brother who turned out to be the absolute opposite in every way. A silly, goofy, snuggly, floppy little muppet of a dog. Highly empathetic and Looooves to make people laugh. Our other dog mostly wanted nothing to do with him, barely tolerating him at the best of times. We thought, surely he’ll learn to love his brother. But 3 years later… nope. Our first dog loves a good pillow so I thought this might make a good gift. I had no idea just HOW good. For some reason ever since our dog opened this gift he’s been obsessed. But so has our other dog. We initially were worried it would become one more thing for them to fight over BUT we were wrong. The dogs have been getting a long SO well! As long as it’s on this pillow, our first dog allows our second dog to come close enough to touch him. They sleep next to each other, they wrestle, there’s no growling or grumping and our first dog will come over and lay next to his brother if he’s laying on this. We’ve started calling it The Peace Pillow. Anyway, I could have just said “it’s great” but it might actually be magic. Your experience may vary.

Super soft, cozy, and great quality Dog Bed
Size: Small 24"x18", Color: White, Size: Small 24"x18", Color: White
This pet mat exceeded my expectations. The material is incredibly soft and plush, and you can tell right away that it’s made with comfort in mind. My pet laid on it immediately, which is always the best sign. It provides just the right amount of cushioning without being too thick or heavy. The quality is excellent — the stitching feels sturdy, the fabric doesn’t shed, and it holds its shape well with regular use. It’s lightweight and easy to move around, making it perfect for use in crates, on the floor, or even on furniture for extra protection. Cleaning is simple, and it still looks great after use. Overall, this mat offers great durability, ease of use, and excellent value for money. It’s stylish, practical, and extremely comfortable for pets. I would absolutely recommend this to anyone looking for a cozy, high-quality mat for their dog or cat 🐾

Cushion for the pooch’n
Size: Small 24"x18", Color: Brown
I’ve been using the ULIGOTA Dog Bed Crate Pad Plush Soft Crate Bed in my dog’s crate for daily resting and overnight sleep. Right out of the package, it’s clearly designed for comfort first. The plush top feels soft and inviting, and it immediately makes the crate look more like a cozy sleeping space rather than a hard plastic tray. Once fluffed up, it provides a decent layer of cushioning that’s noticeably more comfortable than a bare crate floor or thin mat. In terms of fit, it sits well inside standard crate sizes and doesn’t bunch up too badly once settled. The anti-slip bottom helps keep it in place during normal movement, which is especially helpful for dogs that reposition a lot while sleeping. Comfort-wise, it works well for small to medium dogs that just need light padding. It’s warm and soft enough for everyday use, and most dogs seem to settle into it quickly. However, it’s not a high-density or orthopedic-style bed, so it doesn’t offer much support for dogs that need joint relief or extra structure. Durability is average. It holds up fine under normal sleeping use, but it’s not ideal for heavy chewers or dogs that dig aggressively. Like most plush crate pads, it’s more of a comfort layer than a rugged long-term solution. Pros: very soft plush surface, comfortable for everyday crate use, easy fit in standard crates, non-slip backing helps stability Cons: not chew-resistant, limited support for heavier or senior dogs, cushioning is on the thinner side Overall: a solid, budget-friendly crate pad that improves comfort and warmth significantly over a bare crate, but best suited for calm sleepers rather than heavy chewers or dogs needing orthopedic support.
