SS4 Auto 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 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.

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

Fairly stable. Good value for the price
Size: 16 Inch, Size: 16 Inch
Great set of stands. You have to tighten them pretty snugly to minimize wobble. Given they are metal they’ll have a little bit more give than solid wood. Even so, a tall desk I built with them remains stable and level.

I love it!!!
Size: M Desk Unfinished 3/4-in and 1/2-in
Easy to assemble, all the pieces were in the box. I set everything out to be sure. Instructions were easy and clear, took about 10 min to put together. Seems to be quality pipe, strong stable build even at just hand tight. When I put the desk top on it was already level so bonus there. This kit is a great value, before I found the M desk I was looking on Pinterest for pipe leg designs thinking a trip to the hardware store and I could make it for cheaper, which was not the case. I 100% will recommend, and will purchase again.

Real steel pipe
Size: O Desk Unfinished 3/4-in and 1/2-in
This pipe table leg set was great. It's real steel pipe like from the hardware store. It does have a layer of oil on it so that must be stripped using dawn or some other degreaser before handleing and painting. It is also offset in the middle bar so if you use it as a desk you get more leg clearance. I used it as a table base so I bought matching middle braces to set the middle support in the center of the table. Once together it looks great. I highly recommend getting this if you want a good quality pipe base.

Price / Quality - Office Desk - Perfect
Size: H Desk Unfinished 3/4-in and 1/2-in
Purchased two sets to create a custom L shaped desk for the office. Placed a pine stained top. Perfect to handle a monitor, multiple laptops, normal office equipment. Extra benefit is the cross piece at the bottom as a foot rest. Very sturdy while sitting on carpet. Compared to normal pipe material purchased in large box store -- could not have asked for a better product for the price. Looking at other products for additional projects for around the house for the product and vendor. - Highly Recommend.
