SS4 Auto 4 Bank Battery Charger with 3 Bank B.O.S.

This kit combines Dual Pro’s B.O.S. Battery Optimization System - 12V - 3-Bank (PN: BOS12V3) and Dual Pro’s SS4 Auto 40A - 4-Bank Lithium/AGM Battery Charger (PN: SS4AUTO).

B.O.S. (Battery Optimization System) - 12V - 3-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

Flimsy and cheap screws
Screws snapped off when I tried to drill htem in and no matter how I try to get the leg pieces in they will NOT stay. Falls apart, screws snap off, the middle axle holes arent even lined up so you cant install one of the pieces in the first place.

Easy to assemble. Works well. Looks nice.
Color: Light Grey, Color: Light Grey
Works for what we need. Easy to put together. Diagram provided was clear. One of the lil screws didn't fit perfectly, but it works well enough. Came with all the lil tools you need to assemble. Product frame is sturdy and hardware (seems heavy duty enough, metal and not plastic) all fits together very nicely. Would buy again if i need another one.

Great value!
Color: Light Grey
I purchased this for a divider in the sanctuary of our church. Making a private prayer corner.. It is way better than expected. Follow direction . When you make the "M" shape put close together. I had the letter tops to far apart and it complicated things. Otherwise it was awesome. Would definitely buy another one if needed
