RS3 3 Bank Battery Charger with 2 Bank B.O.S.

This kit includes Dual Pro’s B.O.S. Battery Optimization System - 12V - 2-Bank (PN: BOS12V2) and Dual Pro’s RealPRO Series Battery Charger - 18A - 3-6A-Banks - 12V-36V (PN: RS3).

B.O.S. Battery Optimization System - 12V - 2-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

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference. Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design. Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.
