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

Dog lives it
Flavor Name: Chicken, Size: 20-70Lbs
Good solid dog toy. Dog loves it. Dog doesn't chew though it. Just don't step on it, it hurts with bare feet.

No Appeal
Flavor Name: Variety Flavored, Size: 20-70Lbs
6 Golden Retriever household and purchased these hoping they would like them. Unfortunately they do not. They do not seem to have much scent or appeal and went to the bottom of the basket. On the plus side, the seller reached out and offered an appreciated refund. Raised 1 star for response and responsibility.

Dog uninterested
Flavor Name: Bacon, Size: 20-70Lbs
My dog is a huge chewer and is constantly chewing on all sorts of different bones I've gotten her over time. This is the only one I've ever gotten that she refuses to touch, even when repeatedly offered it while I attempt to hype it up. She has a reachable toy bin where I store half her toys, and she pulls things out as wanted, and I swap out the toys in there when she seems to get bored. I left this bone in there for 4 months just to see if she would ever come around to it, but nope. Nothing.

My Dog Hasn't Destroyed Yet But Trying
Flavor Name: Chicken, Size: 20-70Lbs
My large 85-pound dog has chewed-up and destroyed just about every toy I've purchased for him over the past 3 years all within a week of purchase-- this one has lasted intact (although showing signs of wear) loner than most. Overall, I recommend.
