SS2 2 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 - 20A - 2-10A-Banks - 12V/24V (PN: SS2).

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.

  • Available in 6V, 8V, and 12V configuration
  • Up to six batteries in a series
  • Battery Selection and Prediction (BSAP-24) algorithm

Protection
Style: SPF 50
I love this product, especially my husband because it’s all-natural. It contains minerals that leave a slight white residue on the face. While it would be nice to have a clearer texture, it does a beautiful job of protecting you from the sun.

Worked well near the equator
Style: SPF 50
I bought this product because I was going to be in the field for a month, outside, every day, all day, in Tanzania at high altitude. A severe sunburn would be hard to treat in the remote area we were in, but also I am very careful about protecting my skin from aging. I had to have mineral based sunscreen because as a whitewater kayaker I know it’s the only truly water resistant kind and it was going to be sweaty. And since I knew I was going to be putting it on every day, and we didn’t have running water in the field (bucket showers only) I didn’t want it to feel gross. (I really wanted to try the spray but I didn’t want to put anything pressurized in my luggage.) And I had already discovered the Coola face sunscreen (30spf version) which had impressed me with how silky smooth and not greasy it is. Now this IS greasier because it is a higher SPF. BUT I think this product is as good as you’re going to get with the protection you’re getting. Like I said, I’m a white water tiger, so I have used a LOT of mineral sunscreens. This was hands down the most comfortable one I’ve used. And it was effective. I didn’t burn once—only time I did burn was when I forgot to put it on one day toward the end of the trip, when we were out for just a couple hours—and I got the first 2nd degree burn I’ve ever had in my life. That was what this stuff had protected me from, all day every day, the entire trip. I did tan a little but I think that was mostly from the few times I was not covered during short bouts or it was cloudy. For my face I used the Coola 50spf face product.

Love this stuff!
Style: SPF 50
I use this every day and I love how it is frangrance free and creamy. I have a very fair complexion and I will say it leaves a slight white cast but it doesn’t bother me because it almost makes my fairness more creamy looking. My skin texture has improved since wearing it daily and no allergies from it. I highly recommend especially if you have fairer skin otherwise it may leave a cast .

Excellent mineral sunscreen with minimal white cast.
Style: SPF 50
This is one of the healthier sunscreens I’ve found so far. You’re not likely going to find a mineral sunscreen that doesn’t leave some white cast. However, this one rubs in pretty good with minimal cast. You can dab on and rub in fairly easily… as long as you don’t use too much the white cast should be minimal. I am not sure how well this would work on darker skin tones. My arms are a medium skin tone… my legs are more of a light-medium tone. I prefer mineral sunscreens, and this is the best one I found so far and compatible to Supergoop mineral play. If you liked that one, you would likely enjoy this Coola one too.

Would not recommend
Style: SPF 50
I literally never write reviews but felt compelled to write one for this sunscreen because I was very caught off guard by all the positive reviews. This sunscreen leaves the most insane white sheen that never soaks in and gets on EVERYTHING. I put this on and drove to the beach and had sunscreen on my car seat, the steering wheel, the center console, the door, EVERYWHERE! It took forever to clean up and was such a hassle and that was after having let the sunscreen soak into my skin for an hour. Also the sunscreen is really thick and difficult to spread and makes you look ghostly white. Plus, the sunscreen has a really odd odor that reminded me of play dough? That might not be a negative thing for everyone but I found it unpleasant. There are definitely better mineral sunscreens out there. For the price I expected a much better product.
