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

Lay flat handle is a game change
This dog steak is made of quality steel easy to install and has held up overtime. I would highly recommend. I bought this dog steak over two years ago. Immediately and easily screwed it into the ground for a secure hold. The lay flat handle is convenient for attaching a cable or rope to tie your dog up to. The lay flat handle, makes it easy and convenient for mowing your lawn. I have never once pulled it or moved it in order to mow our grass and after two years, it has remained as secure as it was the day I screwed into the ground.

Don’t waste your money
Color: Colorful
My dog wouldn’t have any thing to do with these. The hole where you fill with water doesn’t close in anyway, so water leaks all over. Wouldn’t purchase again.

10/10 Recommend
I purchased this for our trip to Texas from Alabama with our 2 year old American bulldog in tow. I wanted something that was able to keep her secure, but something that would be comfortable for her. I was also concerned about sizing because even though she is a medium sized dog, she has a wide chest. I got an XL. It fit her perfectly with the adjustable straps, it was easy to get it on and off of her, she didn’t mind it at all, and the straps were strong enough to keep her safe and in place.
