SS4 4 Bank Battery Charger with 2 Bank B.O.S.

This kit includes Dual Pros B.O.S. Battery Optimization System - 12V - 2-Bank (PN: BOS12V2) and Dual Pros Sportsman Series Battery Charger - 40A - 4-10A-Banks - 12V-48V (PN: SS4).

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.

  • Available in 6V, 8V, and 12V configuration

  • Up to six batteries in a series

  • Battery Selection and Prediction (BSAP-24) algorithm

Delivers what it promises
Format: Kindle
This book delivers exactly what the title promises—powerful asset protection strategies that actually work. The author expertly explains trusts, estate planning, and legal structures in a way that’s easy to understand but also incredibly effective. As a business owner, I found the sections on passing a company to the next generation particularly valuable. The insights on lawsuit protection and tax-saving strategies alone make this book worth the investment. Whether you own real estate, run a business, or simply want to safeguard your wealth, this is the go-to resource you need. Highly recommended!

This book is for everyone
Format: Kindle
Wealth of information wonderful advice to implement into your trusts and protect your assets. Chapter 2 was most helpful. This chapter covers many different trusts some I have never heard of . The chapter starts off with a quote “ You have to make sure that your assets and your back are protected before you make any big decisions.” Adam Rich. This chapter explains what a trust is. The trust involves three key roles. The grantor, the trustee and the beneficiary. Covers pro and cons of setting up a trust. Explains about revocable and irrevocable trusts. Two trusts that caught my interest are special needs trusts and Medicaid trusts very interesting reads. So much more I only touch on a little. Very good read very informative.

Great for sensitive skin!
Size: 60 Count (Pack of 12)
We absolutely love these water wipes! They’re so gentle on my baby’s skin and have never caused any irritation or redness. I love that they’re mostly water and don’t have a strong smell or harsh ingredients. They’re soft but still durable enough to clean really well without falling apart. I also appreciate that they don’t feel overly wet or soapy just clean and simple.These have become our go-to wipes, especially for sensitive skin. If you’re looking for something gentle, effective, and safe for your little one, I definitely recommend these!
