SS4 Auto 4 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 SS4 Auto 40A - 4-Bank Lithium/AGM Battery Charger (PN: SS4AUTO).

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

The Bible of Self-Improvement
Format: Kindle
First, let's get something out of the way... which version to buy. I ordered my copy on launch day and after dealing with 48 hours of anxiety waiting for it to show up, I couldn't take it any longer and ordered the Kindle version as well. Bottom line... You need them both. One to have right away and always with you, and the book itself to markup, highlight, write in the margins and run through the ringer. Everything in the 2005 release is here, but there's more... so much more. Updated stories from people who have implemented The Success Principles, where they started, and where they are today will keep you engaged and on the edge of your seat. You won't be able to put this book down (but you really have to so you can implement). It is written with the mastery of a thriller novel, yet finessed ever so finely so that you not only learn the principles, but implement them. The new section, "Success in the Digital Age" fills a desperate void. We are overloaded with information, new technology and social media platforms. Most people are guilty of these being replacements for other time-wasting activities but fail to monetize and take advantage of them. Jack clearly lays out how to do it, instead of the digital age controlling you. I've been on pins and needles waiting for the Tenth Anniversary Edition (even though I read the first version 7 times). It is everything you could ask for (and more) in a self-help book. Ordered ten more copies to give as gifts (and so that at least one is always in my office). Congratulations on a job extremely well done. No stone was left unturned.

This book could not only change your life... it could change the world!
Format: Kindle, Format: Kindle
This book is an absolute must read for anyone who wishes to achieve a more successful and happier life. Jack Canfield reveals the specific requirements, methods and principles for breaking through and achieving success in life, work, health and love. So whether you need to boost your team's revenues at the office, expand your personal creativity to figure out that big idea, break out of a negative pattern that is keeping you from finding love, or simply to create more balance in your life, this book will help you pave the way to achieving true and sustainable success. I'd like to add that after I read this book, I loved it so much that I took Jack's life changing workshop - Breakthrough to Success - and I can testify that this stuff works! Because of the workshop and finding the will to follow the timeless principles in this book, I have finally found how to achieve multiple breakthroughs that were eluding me over the years. Yes, the Success Principles absolutely work! One more thing - recently, I've been serving as a strategic consultant to a global humanitarian organization on a project that will transform the lives of millions of people - this has given me the privilege of traveling and meeting people all over the world, including poverty stricken countries like Somalia. (For fun, I'll attach a pix of me in a slum in Rawalpindi Pakistan.) I now see that the one vital component for transforming and lifting the Third World out of poverty is to shift consciousness in exactly the way that the Success Principles encourages. Therefore, I am 100% in support of Jack's vision of bringing the Success Principles to millions of people all over the world. I'm all in!

TAKE IT TO THE NEXT LEVEL
Format: Paperback
Upon reviewing Jack Canfield's 'The Success Principles'; I found it a worthy read. To delve into stereotypes, it will mostly be read by young men. This means that the fundamental weakness of young men needs to be talked about - which is sex. Napoleon Hill devoted a whole chapter to 'Sex Magnetism' in his magnum opus 'Think And Grow Rich.' You should definitely read that book. Staying away from sex for two or three months will definitely build force, and give you a competitive edge. Mr. Canfield's book is remarkable in it's breadth. You need first of all to be responsible for the results you are getting in your life,surround yourself with good people, chunk down your goals, take action, and learn from the feedback you are getting. The weakness in this book is all those people who have good intentions, who want to learn; but who sabotage themselves; or at least at a subconscious level think they are unworthy of reaching their goals. For them I would suggest karma yoga and either Sufi practice or Christian mysticism. The karma yoga will take you to a higher plane than your problems, whereas the Christian mystical training or Sufi training will heal your heart, and stop you from failing again and again. You have a handbook in your hands which will solve many of your problems. If you take action, see how life responds, and work and adapt. Five stars!
