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.

Features:

  • Available in 6V, 8V, and 12V configuration
  • Up to six batteries in a series
  • Battery Selection and Prediction (BSAP-24) algorithm

Carefully Researched Gives Insight To 19Th Century Occurances of: American, Canada, and Mexico!
Format: Hardcover
This book is a treasure as it covers not only the American Civil War but what intricate details are behind it and more, in addition covers the same eras for the Dominion of Canada, and French take over of Mexico along with the factors leading to "Cinco De Mayo," and more. As an avid reader of American History also as a amature historian this book is carefully detailed and gives insight to the racial and political beliefs at the life and times of the 19Th. Century. It deserves a place on your bookshelf and/or library. In these contemporary times, I am still more than pleased the the border frontiers between the Republic of Canada and United States of America remain the: "Longest Undefended Borders" in the entire globe.

Another Thought Provoking Book
Format: Kindle
Having read Professor Taylor's American Republics I greatly anticipated this volume in his series. The examination of both the Canadian and Mexican stories in this book along with the American Civil War helps provide context to the traditional narrative. I find his approach useful as it shows how the interactions between the US and its neighboring nations evolved. I'm hoping he continues the series

A Minority View of our History
Format: Kindle
If you want to learn more about American history from the perspective of minorities, this is a crowning achievement. It is long so I focused on reading the chapters on the US and it gave me an understanding of just how brutal the challenges were but how significant the slow process of building our multicultural society was as well.

Eye opening!
Format: Hardcover
I've read tons of books and biographies connected to American history, perhaps because I'm the son of immigrants, but have never read a survey like this one. By describing in luscious and sometimes horrific detail the wars being fought in Mexico and the main Canadian provinces alongside our Civil War, we get patterns, intersections, and insights that simply would not be available reading about any one struggle. I love this book which is teeming with wonderful portraits and dramatic scenes.

A worthy and worthwhile fourth volume in the series
Format: Kindle
Once again, Taylor frames a critical period of the past in terms of the continent of North America and ties the US Civil War to the one occurring concurrently in Mexico and Canada's move toward Dominion. All thoughtfully told and expertly researched.
