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

This kit includes Dual Pro’s B.O.S. (Battery Optimization System) - 12V - 3-Bank (PN: BOS12V3) and Dual Pro’s 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

Perfect
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
Honestly one of the best headlight restoration kits I’ve used. The instructions were simple, the process was easy to follow, and the results were way better than expected. My headlights were heavily oxidized and yellow, and after using the 2000/3000 grit sanding steps with the ceramic coating, they looked almost brand new again. The ceramic finish made them crystal clear and glossy. Definitely worth the money and much better than cheap polish-only kits.

Very happy with the outcome, worked perfectly
Size: 1 Count (Pack of 1)
I was very happy with the CERAKOTE Ceramic Headlight Restoration Kit. The instructions were simple to follow, and the whole process was much easier than I expected. My headlights were cloudy and dull before using it, but after completing the steps, they looked dramatically clearer and much closer to new. The kit included everything needed, and I liked that it did not require any extra tools or complicated equipment. The results made a noticeable difference in the appearance of the vehicle, and the headlights also seem brighter at night. Overall, this is a great product that does exactly what it claims. I would definitely recommend it to anyone looking for an affordable and effective way to restore foggy headlights.

Highly Recommend – Amazing Results on My Honda Accords!
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
I recently used the Cerakote Headlight Restoration Kit on both my 2008 and 2014 Honda Accords, and I’m genuinely impressed. The headlights on both cars were badly oxidized, hazy, and yellowed from years of sun exposure. After following the kit’s instructions, they look crystal clear and almost like new again. The process is pretty straightforward and beginner-friendly. It does take roughly an hour per headlight set if you follow all the steps carefully and allow proper air drying time before the final clear coat. There’s a bit of elbow grease involved with the sanding and polishing stages, but nothing overly difficult. The kit provides everything you need, and the instructions are clear. The results are excellent! Both cars now have headlights that look factory-fresh. I’m really happy with how bright and clear they are at night. Best part? I saved a ton of money by restoring them instead of buying expensive OEM replacements. The only minor uncertainty is long-term durability (how well the clear coat holds up after a couple years of sun, weather, and car washes), but for the price and the dramatic improvement I saw, it’s absolutely worth it. I’d definitely buy this kit again if needed. Highly recommended for anyone dealing with cloudy headlights. Great product that delivers professional-looking results at a fraction of the cost!

Best product I've tried so far but still temporary. YMMV.
Size: 1 Count (Pack of 1)
This product really does work. It is the best I've used. I purchased in September 2024 and am writing this review in May of 2026, roughly one year and 8 months later. I noticed product failure a little after a year after application and it has been degrading slowly since. Currently the product is visible like a layer of clear paint flaking off and you can physically scratch some off. Here are the pros and cons. Pros: Clarity, relative ease of use, value Cons: Taping and sanding, doesn't last for as long as you own your car as claimed Best used as a temporary fix. Bottom line, would I use it again? Yes. What am I doing today? Replacing the headlights completely. Why? I plan on keeping my car for longer than a year.

Review After Using on 3 Different Cars over 3 years
Size: 1 Count (Pack of 1)
Cerakote Headlight Restoration Kit : After Using on 3 Different Cars over 3 years This is my second time purchasing the Cerakote Headlight Restoration Kit, and I’ve now used it across three different vehicles. At this point, I feel comfortable saying this product genuinely works when used correctly. Before trying this kit, I considered replacing my headlights entirely. The cheapest replacement set I found was around $150 just for the parts. Installation would have required removing the grille, bumper, and other components, which adds time and complexity. For an older vehicle, that didn’t make financial sense. Instead, I chose to restore the original headlights. Cost and Value My first package cost me $17, and I restored two cars with that single kit ( about 9$ per pair). That alone made it worth it. For under $20: I restored two separate vehicles Avoided buying new headlight assemblies Avoided removing the bumper and grille Compared to a $150+ replacement plus labor, the savings are significant. Durability 1 year+ under direct Cali sunlight (currently on year 2 and still good) First Car – Learning the Process The first time I used the kit, my results were decent but not perfect. That was mainly because I didn’t fully understand how sanding and polishing actually work. ( this reoxidized fastest under 8 months, but it was mostly my fault) I didn’t initially realize: The headlight needs to stay wet during sanding Oxidation must be completely removed before applying clear coat Even pressure matters/ 50% overlap coverage when appling ceramic Once I understood that sanding is the most important step, everything improved. Second Car (beater) Major Improvement The second vehicle was heavily oxidized and yellowed. I used the remaining material from that same $17 kit and restored it completely. The clarity difference was dramatic. It looked close to factory condition, and night visibility noticeably improved. That was when I realized the product itself is solid; the key is proper technique. Third Car ; Recent purchase By the third car, the process felt straightforward. I followed the instructions carefully, kept the surface wet while sanding, and applied the clear coat evenly in one smooth pass. The final result was clear, glossy, and uniform. No haze, no streaking. Durability On my first vehicle, the restoration lasted close to a year perfectly( I sold that car this year and it still had clear headlights), and that car was parked outside in direct sun most days. For a DIY kit at this price point, that level of durability is impressive. Final Thoughts I seriously considered spending $150 on replacement headlights( this was cheapest ) and dealing with removing body panels. Instead, I spent $17 and restored two cars. Now having used it on three vehicles, I can say this kit is effective, cost-efficient, and worth the time if you follow the process properly. It does require effort and patience, but the results justify it. I would purchase it again.
