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 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

These are BRIGHT
Color: Yellow & Spot Flood Combo, Color: Yellow & Spot Flood Combo
These are dang BRIGHT! Let’s see how they hold up over time. Using them as Ditch/Spot lights and are great. I had to buy some spade connectors to complete the install but other than that it’s easy to complete the install. I had some brackets from another company to complete my install so the fit looks great.

Color: Yellow & Spot Flood Combo, Color: Yellow & Spot Flood Combo
**Update** Changed from 3 to 4 stars I contacted the seller in regards to the deffective light. They were amazing and sent a replacement immediately. Great communication and customer service, so far so good, if it happens again I will update the review. ___________________________________________________ I loved these lights; they were super easy to install and had great brightness; unfortunately, after 6 months, water started to get inside, and now they don't work anymore; it's a shame... I sent an email to customer service, and I'm still waiting for their response. If anything I'll update this review. If it wasn't for that, I would have given them 5 stars.

CAN be used for simple Home Theater but really shines when playing music.
Style: R-S202BL, Configuration: receiver only
First: YES, you can use this as an AV receiver *IF* you have a simple home theater setup and are willing and know how to run a digital to analog audio converter from your TV to the inputs of the receiver. BestBuy sells an inexpensive and intuitive unit. HOWEVER, if you have several devices associated with your home theater (i.e. more than 2 -- then this probably isn't a great option for you). I generally prefer Vintage Stereo equipment -- My ideal receiver was the Yamaha CR-2020. But sadly, those are hard to come by and have are more expensive and like a used car -- you don't really know what maintenance you have ahead of you. I had inherited a Sony AV receiver that pre-dated HDMI. It worked and I could even program my Logitech remotes with it. However, it really didn't bring the best sound out of my speakers -- a pair of original Large Advents. Plus, it seemed like it was starting to give up the proverbial ghost. My AV setup is pretty simple since I dumped Time Warner -- or whatever they are calling themselves these days. I have a TV, Roku Streaming stick and that's it! I don't have a living room that would accommodate 20 speakers and a sub without tripping over them (my cats and dog and kids shoes provide enough of an obstacle field). The downside -- this isn't really intended to be an AV receiver. No Optical Audio in... no HDMI ports... you have to make it work if you want to use it for your TV as well. I purchased an Insignia Digital to Analog Audio converter -- you plug in the HDMI cable from your TV into the input and use RCA cables as the output to plug into the receiver. This little gizmo was about 25 bucks so I was still saving quite a bit of money over "full-featured" AV receivers. The sound for the TV is fine -- You aren't going to be fooled into thinking you are in an IMax theater or anything. But that wasn't my primary concern. I really wanted my music to sound great. And playing music is where this receiver really shines! I *REALLY* like the Bluetooh connectivity so that I can play from my computer, cell phone without having to use a patch cable to plug into the receiver. It has a very simple interface -- mainly because there just isn't that much functionality. push a few buttons and you'll be able to figure it out without a manual. I know several reviewers have commented on the flimsy clips for the speaker wire but I have some fairly heavy gauge wire and it doesn't works just fine. I don't use banana plus -- just run the copper straight in. Once you get it set up, you shouldn't have a problem -- it isn't like you are constantly re-wiring your speakers. I was able to purchase this for less than 120 bucks and it drives my vintage Large Advents really well. It provides a beautiful full sound for a wide variety of musical genres. Maybe one of these days, I'll stumble across another great vintage receiver. But for the money and the convenience of a remote and bluetooth, this receiver can't be beat. [NECAR}
