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 quadruples 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 series
  • Battery Selection and Prediction (BSAP-24) algorithm
  • Less than 1mA sleep mode
  • Transfer rate up to 7.5A
  • Self-powered
  • Any type of battery chemistry

Used in any application where batteries are in series:

  • Marine
  • Golf
  • Industrial
  • Aerial Equipment
  • Solar Power
  • Electrical Vehicles
  • Communications
  • Defense/Military

Gentle, Effective Cleanser That Leaves Skin Feeling Clean Without Drying
Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Bottle)
I’ve been using the La Roche-Posay Toleriane Purifying Foaming Facial Cleanser for a bit now, and it’s been a really solid addition to my routine. The cleanser has a light, foaming texture that spreads easily and does a great job removing dirt and oil without being harsh. It leaves my skin feeling clean and refreshed, but not tight or overly dry, which is something I’ve struggled with using other face washes. I also appreciate that it’s gentle enough for sensitive skin. There’s no strong fragrance, and it hasn’t caused any irritation or breakouts. It feels like a good balance between being effective and still mild enough for daily use. The bottle is simple and easy to use, and a little goes a long way, so it should last a while.

Gentle, Effective Cleanser With Great Value Refills
Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Refill)
Very reliable cleanser with clean formula and refill option. Fragrance-free, and doesn't irritate my skin. Excellent for daily use. The refill bag is a bit hard to navigate though, kind of floppy to pour from, and the cap broke of for me the first time.

Good Option for Sensitive Skin.
Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Bottle), Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Bottle)
I've been using this foaming facial cleanser for a few months and overall, I've had a good experience with it so far. I usually use it at night, and I start by removing my makeup with micellar water, then use this cleanser in the shower, followed by moisturizer. One thing I will say is that even though my skin tends to lean oily, this cleanser does leave a bit of a tight, slightly dry feeling on my skin after washing. I wouldn't really describe it as super moisturizing, but it's not a dealbreaker for me since I always follow up with moisturizer and it fixes that feeling right away. It also hasn't caused any irritation or breakouts for me, which is a big plus since I do have sensitive skin. It definitely feels non-greasy and very lightweight. The texture comes out as a gel, but it foams up really easily once you start using it. I also don't notice much fragrance in it, which makes it a good option for sensitive skin overall. Overall, I'd say it's a good product to try out. Just be aware that it can feel a little drying afterward!

Good quality product and value for the money
Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Bottle)
I girl loves this product so much that I always buy one before the one been used runs out. Aside from all the vitamins and minerals included in this formula, one can tell how good the product is by just using for a short period of time. It has never irritated my skin nor my girl’s. The texture is perfect “ not to runny/ not to lose. The container is mostly a value pack, so it is not very portable, but at the end I prefect a big size to make up my value for the money. I recommend the product and will continue buying it.

Skin feels so clean
Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Bottle)
This cleanser is awesome for oily skin. Little to no scent and face feels soooo clean after. Very convenient pump and love buying in this larger size. If you have dry/combo skin, this can be a little too drying. Luckily, LRP has a version of this for dry skin that's incredible, too!
