RS3 3 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 RealPRO Series Battery Charger - 18A - 3-6A-Banks - 12V-36V (PN: RS3).

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.

A Lungful of Freedom
Size: 9.7" x 9.3" x 1.8"
Dateline: The Passenger-Side Footwell of a Toyota Venza, Sunday Night. We spend our lives in sealed metal boxes, hurtling through a thick, invisible soup of our own collective filth. A foul cocktail of exhaust fumes, road dust, tire particles, and whatever strange, pollen-based miasma the world decides to throw at us on any given day. To breathe that poison in, unfiltered, is an act of slow, unwitting suicide. You need a line of defense. A gatekeeper for your own lungs. Enter the Bosch 6055C HEPA Cabin Air Filter. It is not a glamorous part. It is not a performance upgrade that adds horsepower or prestige. It is a simple, pleated rectangle of paper and charcoal, a humble guardian destined to live out its days in a dark plastic cave behind your glovebox. But its mission is a noble one. The replacement process is a moment of pure, unadulterated, five-minute victory over the dealership's service department. You pop open the glovebox, you unclip the old filter tray, and you pull out the old soldier. And what you find is a horror show. A grey, matted testament to the unseen war it has been fighting on your behalf, choked with leaves, dirt, and the ghosts of a thousand diesel trucks. It is the face of the enemy. You unwrap the new Bosch filter. It feels solid, well-made. The pleats are clean and numerous. I laid it side-by-side with the outgoing Denso filter—a brand that supplies the automakers themselves—and I could find no meaningful difference. The quality was equal. The construction, robust. This was no flimsy, cut-rate pretender. This was a serious piece of hardware from a serious company. You slide the clean, white Bosch into the tray, snap it back into its dark little home, and close the glovebox. The deed is done. You have performed a life-saving transplant on your vehicle's respiratory system in less time than it takes to listen to a single pop song. And the value… the value is the sweet, sweet punchline. For a fraction of what a dealership would charge you for the same simple service, you have installed a top-tier, HEPA-grade filter from one of the most respected names in the business. You have guaranteed yourself a clean, breathable bubble of personal space as you navigate the toxic jungle of the modern roadway. This is not just a filter; it's a small, affordable act of rebellion. It’s a declaration that you, and you alone, are the master of the air you breathe. It is a simple, effective, and profoundly satisfying piece of gear. Highly recommended.

Great Upgrade to your Cabin Filter. Fits 2018 Subaru Outback
Size: 9.7" x 9.3" x 1.8"
This is a great filter upgrade to your cabin filter. This is better than the Subi standard part. Fits my Subaru outback. NOTE: Subi marks their filter with an 'up' arrow; however, this filter is marked with a 'airflow' direction. Direction of air flow is toward the blower motor so it will point downward when you install it.

Air flow direction
Size: 9.7" x 9.3" x 1.8"
Good product. Fits fine. This is not a Toyota part so Air Flow Arrows on filter should face down in a 2015 Toyota Rav4.
