RS4 4 Bank Battery Charger with 3 Bank B.O.S.

This kit includes Dual Pro’s B.O.S. Battery Optimization System - 12V - 3-Bank (PN: BOS12V3) and Dual Pro’s RealPRO Series Battery Charger - 24A - 4-Bank (PN: RS4).

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.

Features:

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

Used in Any Application Where Batteries Are in Series:

  • Aerial Equipment
  • Solar Power
  • Electrical Vehicles
  • Communications
  • Defense/Military

Decent for the price
Color: 2 Dark Brown, Color: 2 Dark Brown
Bought the color 2 thinking it would be brown but it’s almost Black (my own ignorance). I saw a YT vid by Kie Rashon where she sort of left the front of her hair out so I was hoping to do the same but it’s too dark for my hair (you can’t tell in the pics). I would recommend checking Kie out on YT for more details. I do like it though so I will probably give this one to my sister and reorder a different color. Wish they provided pics of how the wig in other colors look. Edit: So I repurchased this piece in DR Hazelnut Brown (the lighter color). I took some leave out in the front so please note that’s my hairline, not the wig’s. It blended well with my hair color. My texture is a little curlier but I just did a braid out on the front to help it blend. Wig tangles very easily. I’m going to experiment with co-washing to see if that reverts it to its origami condition.

Not this one
Color: 1B Off Black
After buying my first Outre wig I have bought several since until I bought this particular one and I was disappointed from the moment I open the package. The look, texture, fullness, or lack of fullness was very disappointing. The wig only cost 30.00 dollars but had I bought it in a wig shop it probably would have cost much more, but when you order online that is a chance that you take. I wouldn't recommend this particular wig if you are looking for the look that the picture portrays. Try one of Outre's others.

Doesn’t last long
Color: DR HAZELNUT BROWN, Color: DR HAZELNUT BROWN
I love a synthetic wavy wig but this one didn’t even last the entire weekend like most do. Look very cute the first day but after that it just didn’t do what I needed it to do any
