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 quadruples 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 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

Good value
Size: 40, Color: Black With Black Strip
My husband and brother in law both found these pants to fit a little smaller than regular dress pants.....mostly they were tighter in the thighs but the length/waist was perfect. They each ordered a size or two up and had the pants tailors to fit. They looked very sharp and were of a good quality considering they were not super expensive. I hope they have the chance to wear these more often!

Reasonable quality, slightly small, definitely unhemmed
Size: 42, Color: White With Black Strip, Size: 42, Color: White With Black Strip
If these pants are the right look for what you want/need, they're a reasonably good quality option. But that said, in practice these looked a little "cheesy" with the black stripe. I can't say for sure that's a result of how the product is made/how it looks, but I just couldn't see myself wearing them. That's assuming I could wear them... In terms of fit, they were slightly small in the waist for both pairs I ordered. I'm not sure what I thought they meant when I read that they were unhemmed, but for those looking for pants to take out of the box and wear... these aren't for you. The ankles are not "finished" and require hemming to make them look acceptable. (This was my fault, so I didn't count off for this)

They stand out, and are flashy, but sizing is complicated.
Size: 34, Color: Black With White Strip, Size: 34, Color: Black With White Strip
High-quality pants and flashy. The stripe adds a lot of attention for reasons both good and bad. The materials they were made are excellent quality. Pants are thick, but not too thick, and are lightweight, guaranteeing easy movement. Comfortable - could wear these all day. I do love their appearance. They made me feel like a million bucks. :) The only problem is sizing and fit. I normally wear size 34 for waist in jeans and dress pants like these, but the 34 I got didn't fit at all - too tight. So, I ordered a 36, and it fit, but barely. When I sat down, there was too much tightness in my "masculine area". I also ordered a 38, and, well, they were just too big - practically hung off me. A 37 would probably work for me in these, but they don't offer such a size. I have to return the 34 and 38. Will keep the 36, see if I can have it altered in some way. Length was fine. Being 1.86 meters, often the length in these pants is a little on the short side. In the photo, I'm wearing size 36 and the black pair with the gold stripe, which is actually more of a flashy yellow. I liked how I looked in them, but they were a little too tight at times, the belt wasn't even necessary. It enhanced the outfit though, don't you think.
