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 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

Color: 8-in-1 Deluxe Wine Set - Silver
Love love this set!!! Especially the wine aerator/Pourer it’s a game changer especially if you like to entertain. You can line up a couple of different variety of wine bottles attach the pourers and let your guest serve themselves. The wine pourer is measured so you don’t over pour and it automatically stops… love this and getting a few more pourers to have ready when I have guests iver!!

A Disaster, Don’t Buy 8-in-1 Set
Color: 8-in-1 Deluxe Wine Set - Silver
A Disaster. Can only give this 8-in-1 gift set one star. The electric aerator has a mind of its own. The second time it was used, an hour after the first pour, it then decided to start pouring on its own, drenching the counter and floor with wine until my wife and I figured out what was going on and got up to try to shut it off. It wouldn’t shut off and had to be pulled out of the wine bottle still running on its own. Half of a very good bottle of wine was wasted. It never did shut off. Had to be thrown in the trash outside still running. Funny now as I describe it, but not funny at all when it happened. The rest of the set so far is working well. If you have to buy this brand, please don’t buy the set with the electric aerator. It's fully automatic all right, but that’s a very very bad thing.

Effortless and Elegant Wine Opener!
Color: 7-in-1 Black, Size: Rechargeable Set
I absolutely love my CIRCLE JOY Rechargeable Wine Opener! From the moment I opened the box, I could tell it was well-made and stylish. The sleek design looks great on my kitchen counter, and it feels sturdy in my hand. The performance is amazing — it removes corks quickly and smoothly with just the press of a button. No more struggling with manual corkscrews or broken corks! The built-in rechargeable battery lasts a long time, and the charging base keeps everything neat and organized. It also comes with handy accessories like the foil cutter, which works perfectly every time. I’ve used it for several dinner parties, and my guests are always impressed by how effortless it is to open a bottle. If you enjoy wine and want to make your experience easier and more elegant, this electric wine opener is a must-have. It’s functional, beautiful, and makes a perfect gift for any wine lover! 🍷

Fabulous Product!
Color: 7-in-1 Black, Size: Rechargeable Set
This wine opener is fabulous! Foil cutter is sharp and works well. Easily removes the cork, then releases the cork from the corkscrew with a touch of a button. Also seals the wine which I have stored on its side in my wine refrigerator without any leaks. Charges quickly and I have opened many bottles of wine without needing to recharge it. Have had this item for a few months and if it continues to work this well, I will be amazed and very satisfied. Very reasonably priced as compared with similar products that I considered. Most of the other products cost more and did not do all of the functions that the Circle Joy does.
