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

This kit includes Dual Pros B.O.S. Battery Optimization System - 12V - 2-Bank (PN: BOS12V2) and Dual Pros SS3 Auto 30A - 3-Bank Lithium/AGM Battery Charger (PN: SS3AUTO).

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

Great Protection w/out the White Cast
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
We had been using the ThinkBaby mineral sunscreen for years. I wanted to look for a similar alternative but with less white cast. I actually bought this on a whim because it had the fastest shipping at the time (needed it for an outdoor event we were going to). We are now three purchases deep with this product. In my opinion, I think it gives the same amount of sun protection as before without the white cast. It rubs in great. Non-greasy. Initially, the lack of added fragrance was a little off-putting because we were so used to the typical coconut or citrus scents, but we all got used to it. Definitely on my list of subscription purchases now. I wish it was available in a larger size.

Smells good, covers well, it does leave a white sheen, I don’t need to reapply.
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I use this just once on my face in the morning, apply makeup over it, and I haven’t burned yet! Been using it for two years now. Unfortunate thing is that my face is not tan at all because it doesn’t allow any rays. LOL So I my makeup has to match the rest of my body… I stay under an umbrella at the beach for about half of the time that I’m there. Otherwise I am out in the sun. And I do not reapply this. I am in the sun between the hours of 9 and 1 PM and I’m in and out of the shade and sun half of the time. Still no burning. Actually I don’t think I reapplied it at all once I got home from the beach and I was out at the pool regularly for another hour with no shade. So it seems to be pretty darn good! Some people say they don’t like the smell, but I specifically bought it because I love love love the coconut smell. My daughter says it smells like bananas but I don’t like the smell of bananas and I don’t think it smells like that. It does definitely leave a white sheen. Hence my need for make up.

Great for Hawaii!
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I spent hours trying to find a sunscreen that was “reef safe” since I was going to be spending a lot of time near corals and this was the best one I found. It doesn’t have any of the 3 ‘O’ ingredients that are known to damage reefs. And the zinc is non nano as well. Sunscreen goes on easily. One of the better mineral sunscreens I’ve tried, this one actually smooths out like lotion and feels hydrating. Only leaves a slight pinkish hue, but that is inevitable with mineral sunscreens (that’s literally how they work in reflecting the sun). I could feel it on even in the ocean so I get protected, but still reapplied almost every 2 hours. No burns! I didn’t use it on my face but my partner did and it never stung his eyes nor caused any breakouts!

Stick format is thick and difficult to rub in moderate climates
Style: SPF 50, Size: 1 count (Pack of 1)
I wanted to like it because the small stick format seemed very convenient to keep in my bag for emergency sunscreen reapplication with no chance of leaks. But I think I have learned my lesson about stick sunscreen - in order to hold together in a stick, it has to have a thick and chalky consistency. Which makes it hard to apply and hard to rub in. It's so thick that if I rub the stick over my entire face it feels like I'm applying way too much with a super heavy white cast, and if I dab here and there and try to spread it around, it's so thick it doesn't feel like it spreads into good coverage. The scent is fine. Update: I have found a specific use case for this - in extreme UV conditions like the equatorial tropics in midsummer, it's a good base layer under a more liquid mineral sunscreen, to add extra protection to the most exposed skin, like tops of shoulders, chest, nose and top of forehead. The thickness makes it protect better. It also softens a little and rubs in better in hot temps.

Needs to be warmed, but works great for quick face re-application
Style: SPF 50, Size: 1 count (Pack of 1)
I love mineral sunscreen, it really works the best. But I also do not love mineral sunscreen because it's hard to apply. I don't think it matters what you do, they're just always difficult to apply and always leaving the white. This one isn't much different. I'm a scuba diver and my face sunscreen is washed off quickly doing multiple dives. I also get a weird "mask sunburn" if I don't reapply... but since I'm a diver I can't bring myself to buy or wear sunscreen that's not reef safe into the ocean. I was unsure if this would work because it's pretty solid. I threw it in my bag and once the sun warmed it up a little, I was able to apply it fairly easily between dives. I don't think it works unless it's warmed a bit first, but I like it for this purpose.
