SS3 3 Bank Battery Charger with 2 Bank B.O.S.

This kit includes Dual Pro’s B.O.S. Battery Optimization System - 12V - 2-Bank (PN: BOS12V2) and Dual Pro’s Sportsman Series Battery Charger - 30A - 3-10A-Banks - 12V-36V (PN: SS3).

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.

Features:

  • Available in 6V, 8V, and 12V configuration
  • Up to six batteries in a 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

Perfect 220V Power Extender
Used this on a recent European trip and it worked perfectly, providing me with the extra outlets I needed to power my PC, multiple chargers and phones. European pin connection with US outlets and USBs. If you are planning to go to a country with 220V, don't expect to use a 110V extender with a plug connector - it may well burn out (though most electronics will work fine when connected to 220 via their chargers and power supplies). This one is compact and easy to pack. I have a larger 220v strip purchased for another trip and this one will be traveling with me from now on due to its compact size and lower weight.

Absolutely great for travel but not enough wattage to charge a macbook without the macbook brick.
So this thing is absolutely amazing for travel. The extension cord is a great length. The usb ports are secure and snug and it really works very well, it's by FAR my favorite adapter to travel with. I do have one nitpick - the photos clearly show it charging a macbook and yes, it can but not with a straight cable you still need to plug in the macbook power brick to it. I was hoping to avoid that but this adapter does not have enough wattage to charge a macbook without the brick. I included two photos showing the difference in wattage between this and an macbook power brick.

Great for use in Italy!
We spent 3 weeks in Italy in May of 2023. This was so easy to use for making sure all of our cell phones and power bricks were fully charged for the next day of discovery while in Italy. Plugged in effortlessly everywhere we stayed in Italy. We used all the charging ports and the USA outlets for two dual voltage power packs (remember the Italian grid is 240VAC not 120VAC like in USA) and my dual voltage CPAP power brick. No problems any where - it worked flawlessly. I would not suggest using it for curling irons or blow dryers or any very high wattage devices and anything you plug into it that does not say dual voltage on the device may be destroyed and possible catch fire! So do be aware of what you use with it as it does not drop the voltage to 120VAC from the 240VAC Italian wall outlets. Nice feature is that it comes with an adapter you can use when you get back to USA so you can use it at home till you pack your bags for the next trip!

Worked as expected, lots of USB ports.
Just used on my trip to Paris, worked well and I liked having so many USB ports. The long cord was great because my hotel was rather vintage and the outlets weren't in convenient places. Glad to see it will also work for my next trip. I appreciated that it came with adapters for the US also so I could test it at home before I left.

Perfect for travel!
These "extension cord" power adapters were perfect for us during a recent trip to Europe! They come with multiple adapters so that you can use the adapter in several countries. Best of all, one of the adapters is for North America, so we can still use them at home! Each adapter has three 3-prong plug sockets (meaning you can use either 2-prong or 3-prong plugs), one of which is set slightly apart from the other two to accommodate a larger plug. Each has four USB ports, plus one USB-C port. Plus, it has a 5-foot extension cord, so you can reach that one socket that never seems to be where you actually need it to be! That made it perfect to be able to set the adapter on the bedside table and charge all of our devices at once, but still keep our phones close at hand for checking time, setting alarms, etc. With all of that in one little box, we were able to eliminate the bag-full of various adapters we've had to pack for past trips. Definitely recommend these for your travel needs!
