RS3 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 RealPRO Series Battery Charger - 18A - 3-6A-Banks - 12V-36V (PN: RS3).

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

  • Aerial Equipment
  • Solar Power
  • Electrical Vehicles

  • Defense/Military

High quality
Color: 5pack, Size: Large
Our Aussie lives these toys! She hasn’t torn any up yet. She did manage to tear off an ear from the cheetah but the rest of the toy is intact after a lot of tugging and biting. Comes with 2 squeakers for more fun. She loves playing with these and will toss them up in the air and chase it by herself.

Mixed Bag of Dog Squeaky Toys for Small Dogs
Color: 12pack, Size: Small
I recently purchased the SHARLOVY Dog Squeaky Toys for Small Dogs, a pack of stuffed animal puppy toys, and while they offer some positive aspects, there are a few drawbacks that prevent me from giving them a higher rating. One positive aspect of this toy pack is the variety it offers. With 12 different plush dog toys included, there is a range of options to keep my small dog entertained and engaged. The cute designs and soft textures are appealing, and they provide a good selection for different play sessions. The squeaky feature of these toys can be entertaining for dogs, and it adds an element of interactive play. The squeaker is relatively durable and has held up reasonably well during playtime, adding an extra level of excitement for my dog. However, the durability of these toys is a concern. While they are suitable for small dogs and light chewers, they may not withstand the rigorous chewing of more aggressive chewers or larger breeds. The seams on some toys have come apart relatively quickly, resulting in stuffing coming out or potential choking hazards. It is important to supervise playtime and monitor the condition of the toys closely. Another drawback is the size of the toys. While they are marketed for small dogs, some of the toys in the pack are quite small and may pose a choking risk for dogs that are prone to swallowing or have a tendency to tear apart toys. It is essential to choose the appropriate toy size based on your dog's breed and chewing habits. In terms of value for money, the price point for this toy pack is reasonable considering the number of toys included. However, the longevity of the toys may impact the overall value, as they may need to be replaced more frequently for dogs that are rough with their toys. In conclusion, the SHARLOVY Dog Squeaky Toys for Small Dogs offer a variety of cute and soft toys that can entertain small dogs during playtime. The squeaky feature adds to the fun, but the durability of the toys and potential choking hazards are concerns. It is important to choose appropriate toy sizes and supervise playtime to ensure the safety of your furry friend. If you have a small dog and are looking for a variety of soft and squeaky toys, this pack may be worth considering. However, if your dog is an aggressive chewer or larger in size, it may be more prudent to explore more durable and size-appropriate options to ensure the toys can withstand your dog's play habits.
