SS3 Auto 3 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 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.

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

Impressed so far
Style: Standard Grip, Size: 25ft, Color: Chartreuse
I have a large back yard, a pool and a stationary hose reel bolted to the house that holds around 250 feet of hose (depending on the hose). During the summer especially, we use this hose a lot. The reel had 200 feet of pretty good quality, heavy duty residential hose on it. That hose lasted over 20 years but was starting to show it's age and had been repaired several times. What's more, my wife hated the stuff. Her primary complaint was how heavy it was. She really struggled to drag it around the yard or wind it back on the reel. So it was time to replace it. My criteria: brass fittings, reasonably heavy duty and durable, decent price. Her criteria, lighter! So I searched the reviews and looked at damn near everything amazon sells and picked this stuff. I ended up buying two 50 foot hoses and one 100 foot hose. So, here's what I think. The hose ends are heavy duty brass and well crimped. The little bits of plastic sleeve on each end are just branding and don't provide any other useful purpose. This isn't a criticism, just an observation. I cut them off. As others have mentioned, the female fittings are crimped a little tight. This makes it somewhat difficult to tighten them without twisting the hose. I put a little white lithium grease on mine and held the things in my hand - twisting back and forth until they lubed up and loosened up. No harm, no foul, I'd rather a little tight than loose. Once that was done, I connected all the sections and stretched the whole thing out in the yard. I connected one end to the faucet (hose reel), slapped a nozzle on the other end and turned on the water. It was a warm summer day, I let the hose fill with water and then went down the entire 200 foot length untwisting and straightening it all out. Then I left it bake in the sun for a couple hours under pressure. After that I turned off the water, and started inspecting the hose. I have about 80lbs of water pressure, left under pressure and cooking in the sun, the hose definitely swelled a little diameter wise, but no bulges or anything untoward. Connections all looked good, no leaks or malfunctions. So, I turned off the water and took off the nozzle and started winding it up on the reel. Now right away I could tell that this stuff was more pliable and significantly lighter then the hose it replaced. I carefully spooled it up on the reel and threaded a brass shutoff and brass quick connector on the end. That was the middle of June, 2023. It's now December 2023. The verdict. I like the stuff, and more importantly, so does my wife. From my perspective, I like the color, it's easy to see and find in the grass, I don't trip over it or worry about not seeing it before I run over it while cutting the grass (you can laugh, but that accounted for one of the previous "repairs" I mentioned earlier). Now, when you pull hose off a reel, it tends to come off pretty straight, which automatically alleviates a bunch of twisting and kinking issues. Still, as you drag this stuff around the yard it keeps its shape pretty well and doesn't twist up or kink. It's flexible and yet "stiff" enough to drag around corners without issue. The hose itself has definitely faded a little colorwise, the end that gets the most use is less orange then the hose that spends most of its time wrapped on the reel, but not unduly so. After a summer of use, I'd have to say it's held up well, without any signs of terminal wear and tear. What does my wife think? She loves the stuff. It's much easier for her to use and wind back up. She really is the primary user, she does 90% of the pool "stuff", plant tending, gardening and watering. If she likes it, I'm good. So, we'll see, in a couple more years, if this hose doesn't hold up, I'll come back and let you know. For now I'd have to say, if you need a new hose, try this stuff.

Great hose!
Style: Standard Grip, Size: 100ft, Color: Chartreuse
5 stars without hesitation. This Flexzilla Garden Hose 5/8 in. x 100 ft. is legitimately one of the best hoses I’ve used. It’s actually flexible like advertised, doesn’t fight you every time you move it around, and it feels way more durable than the cheap stiff hoses from big box stores. I honestly don’t understand a lot of the complaints, mine has held up great, doesn’t kink nearly as bad as others I’ve owned, and is super easy to coil up. Solid hose.

If you want to buy your last hose then flexzilla is your hose.
Style: Standard Grip, Size: 50ft, Color: Chartreuse
O.K. if you are reading my review I can honestly say that I don't think anyone knows what they are buying with this hose like I do as Amazon has the record of when I bought 100 feet of this hose. Long Long Long term user=purchased in 2017. I used this hose today and it looks-feels-works like it did the day I hooked it up on my reel. So flexible you can use it for a tourniquet if required. Hot-cold it don't matter this hose is the best. I am 70 yrs. old and it is the best hose I ever used in my life. Buy this hose once and then be done. Never kinks and not to heavy when moving around. Buy some and get on with whatever work you need to wash and then roll it up and forget about it.

Hose kinks.
Style: Standard Grip, Size: 100ft, Color: Chartreuse
I bought this hose 2 months ago and really like how light it is and easy to pull around the yard. However, I am having a problem with it kinking all of the time. It is really frustrating to have to go back and straighten it out when I am watering.
