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

This kit combines Dual Pro’s B.O.S. Battery Optimization System - 12V - 3-Bank (PN: BOS12V3) and Dual Pro’s SS3 Auto 30A - 3-Bank Lithium/AGM Battery Charger (PN: SS3AUTO).

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

Eucerin for the Win...Again!
I love this tinted sunscreen. It's so lightweight and blends in really well. Since it blends in, it is good for all shades of skin. It doesn't have a strong smell like a lot of other sunscreens have, so that is a huge bonus. So far I'm really loving it. I am definitely a Eucerin girly. I love all things Eucerin at this point.

A hydrating sunscreen but won’t provide the coverage
I’ve been using CeraVe sunscreen, so that’s my baseline. It’s thicker, slightly pigmented, and very hydrating.. Switching to Eucerin felt like moving from a cozy blanket to a light sheet. It’s definitely thinner and less pigmented, so at first it didn’t give me that same immediate glow or coverage I was used to. That said, on its own, it’s still a good sunscreen. It spreads easily, feels comfortable, and does the job without heaviness. After using it for a while, I’ve kind of settled into a rhythm: • If I want a bit of coverage and that hydrated, supple finish → I reach for CeraVe • If I just need straightforward sun protection → Eucerin works perfectly fine One small downside is the packaging. The pump is convenient, but toward the end, I can already tell there’ll be product left that’s hard to get out since you can’t really squeeze or open it easily. Overall, I’d say Eucerin is a solid, lightweight sunscreen. Just don’t expect that tinted, slightly “makeup-like” effect if you’re coming from something like CeraVe. It’s more of a quiet, reliable everyday option than a multitasking one.

Ok for sunscreen
Works fine as sunscreen. Did make me look a little red but might be a reaction as I have very sensitive skin. Didn't notice any color change so basically it's just sunscreen.

Great sunscreen that feels light on skin
Great sunscreen that matches my skin tone and is very light. Its not makeup and also doesn't leave any white sunscreen residue. I can have sensitive skin when it comes to sunscreen and this is very gentle on my skin. Highly recommend!
