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

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

Shirt worth buying several times
Size: XX-Large, Color: Anthracite Polo Stripe
Purchased another of same order and have found them to be excellent. Comfort, sizing, and quality. Can be dressed up or dressed down and they look great either way. Worn in very hot weather and have not been oppressed by sweat. Nice. Will be purchasing more. Sizing was great. Loose and long enough to land just right over pants pocket top.

Great Quality and Comfortable Fit
Size: Large, Color: Washed Blue
I picked up the Amazon Essentials Men’s Golf Polo Shirt, and I’m really impressed. The fabric is soft, breathable, and lightweight — perfect for hot days on the golf course or casual wear. The fit is spot-on, not too tight or too loose, and it looks sharp tucked in or out. It’s held up well after multiple washes without shrinking or losing shape. For the price, it’s excellent quality and a great value. If you need a reliable, comfortable polo for sports or everyday wear, this one is a solid choice. Highly recommend!

Good quality, but runs a bit short
Size: X-Large, Color: Light Grey Heather
Overall, this is a solid polo for the price. The fabric quality is better than expected, with a nice balance of softness and durability. It’s not paper-thin, but not heavy either, and it does a good job wicking moisture and drying quickly, which is exactly what you want from a golf-style shirt. Functionally, it works well for casual wear, work, or being mildly athletic without committing to actual exercise. Sizing is mostly on point, and I didn't notice any shrinkage after washing, but I always make sure to air dry this type of material and not throw it in the dryer. My only real gripe is the length. It feels like the shirt should be about 1–2 inches longer. If you raise your arms, people may catch a glimpse of your six-pack (hopefully), and if you bend over… well, let’s just say you'll want to be mindful of who's behind you. If Amazon fixed the length, this would be an easy five-star staple.
