RS3 3 Bank Battery Charger with 3 Bank B.O.S.

This kit includes Dual Pros B.O.S. (Battery Optimization System) - 12V - 3-Bank (PN: BOS12V3) and Dual Pros RealPRO Series Battery Charger - 18A - 3-6A-Banks - 12V-36V (PN: RS3).

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.

  • Available in 6V, 8V, and 12V configuration

  • Up to six batteries in a series

  • Battery Selection and Prediction (BSAP-24) algorithm

Excellent Pepper Grinder
Color: Upgrade Black, Size: Rechargeable
I've had several pepper grinders over the years, and none was as easy and smooth to use as this one. It fills easily, and it grinds evenly and smoothly with a gentle press of the button. I am glad there are two, just in case one does give out, I will have the other to use, as I am not interested in grinding salt. It runs so effortlessly that you have to be a little careful when picking it up that you do not accidentally engage the button before you want the pepper to come out. I love it, and came back here after using it for two months just to let you know.

Greatest Kitchen Item I've Bought in Years
Color: Upgrade Black, Size: Rechargeable
These grinders are awesome. No more tedious grinding, or endless shaking! I love the adjustable grind levels (I like mine fairly coarse), and these hold a charge for a long time - months. My friends are super impressed when they visit, and will probably be buying these too.

Fast and efficient!
Color: Upgrade Black, Size: Rechargeable
These are a very nice set. Our other pair started grinding the salt and pepper as soon as you flipped it over and made a mess. This set here you have to push the button first. Also it is faster at grinding. Recommend!

Who knew laziness could be so rewarding?!
Color: Upgrade Black, Size: Rechargeable
Super happy with this purchase. With the press of a button I have freshly ground salt and pepper...makes a big difference in taste. I appreciate the lighted bottoms which make it easier to see the quantity being dispensed. The charge has lasted a full month so far with near daily use. They are attractive on my counter and the tray they sit in collects the loosened remnants and is very easy to clean. May give as gifts this year!

Poor Grind Mechanisms
Color: Upgrade Black, Size: Rechargeable
Salt grinder fell apart in 6 weeks. The item looks nice, but the grind settings on both the salt and pepper did not yield truly different grind. They always came out the same size, regardless of setting. About 5 weeks in, the clear plastic bottom came off of the salt grinder. I wasn't even using rock salt, just coarse salt. I could not get the piece back in. Then, the entire grind assembly came out as I was cooking. This item did not even get daily use. I purchased a different brand several years ago, I wish I had purchased that one again. I thought I was getting a good deal based on reviews. **UPDATED 9/19** Seller made reasonable accommodations to make it right. Very pleased with how this was handled. Stars reflect customer service,
