Victron 100A Battery Isolator Argodiode 100-3AC: High-Efficiency Schottky Diode Battery Isolator for Dual and Multi-Bank Charging

Reliable Simultaneous Charging Without Battery Interconnection

The Victron 100A Battery Isolator Argodiode 100-3AC is a robust diode battery isolator engineered to enable simultaneous charging of 3 separate battery banks from a single alternator, without electrically connecting the batteries together. This ensures that discharging an accessory or auxiliary battery—such as a house bank in a caravan, boat, or 4WD—will not drain the starter battery, preserving engine start capability and reducing the risk of being stranded. Unlike generic split-charge relays or basic isolators, this Victron unit uses advanced Schottky diode technology to minimise voltage drop, delivering more efficient charging and longer battery life.

Designed for 12V and 24V DC systems, this isolator is ideal for marine, automotive, and off-grid applications where reliable multi-battery management is critical. Its low forward voltage drop—approximately 0.3 V at low current and 0.45 V at rated output—reduces energy loss and heat generation, ensuring more of the alternator’s output reaches your batteries. This is a significant advantage over conventional silicon diode isolators, which can drop 0.7 V or more, leading to chronic undercharging and premature battery failure.

Advanced Schottky Diode Technology for Superior Performance

At the core of the Victron 100A Battery Isolator Argodiode 100-3AC are high-efficiency Schottky diodes, which provide a lower forward voltage drop compared to standard PN-junction diodes. This means less power is wasted as heat, and the alternator can operate closer to its intended voltage setpoint. The integrated voltage compensation diode allows you to fine-tune the alternator’s output voltage to offset the small remaining drop, ensuring batteries reach a full state of charge. This feature is especially valuable in systems where battery longevity and performance are paramount, such as in deep-cycle AGM or lithium battery setups.

Additionally, the Victron 100A Battery Isolator Argodiode 100-3AC includes a current-limited alternator energize input which is essential for modern alternators that require a DC voltage on the B+ terminal to initiate charging. Without this input, a diode isolator would block the return voltage, preventing the alternator from starting. The energize circuit provides a safe, controlled current to the B+ terminal when the engine run/stop switch is closed, ensuring reliable alternator activation.

Built for Demanding Environments

Victron’s Argo Diode isolators are constructed with a durable anodised aluminium heat sink that efficiently dissipates heat, allowing continuous operation at high currents without thermal throttling. The compact footprint—60 x 120 x 115 mm (2.4 x 4.7 x 4.5 inches)—and light weight of 0.8 kg (1.8 lbs) make installation straightforward in tight engine bays or electrical compartments. Heavy-duty M6 Studs stud terminals ensure secure, low-resistance connections for high-current cables, while the 6.3 mm Faston connectors for compensation and energize simplify wiring.

All models are rated for mounting on non-flammable surfaces and are tested to withstand the vibration, temperature extremes, and salt-laden air common in marine and automotive environments. This rugged design reduces the risk of premature failure and electrical faults that can occur with lesser-quality isolators.

Key Features

  • Simultaneous charging of 3 battery banks from one alternator without interconnection
  • Low voltage drop Schottky diodes: ~0.3 V at low current, ~0.45 V at rated output
  • Integrated voltage compensation diode to optimise alternator output
  • Current-limited alternator energize input for modern alternators
  • Heavy-duty M6 Studs stud terminals for secure high-current connections
  • Compact, lightweight aluminium heat sink for efficient cooling
  • Suitable for 12V and 24V DC systems
  • Robust construction for marine, automotive, and off-grid use

Applications

The Victron 100A Battery Isolator Argodiode 100-3AC is an excellent choice for a wide range of dual-battery and multi-battery systems, including:

  • Marine vessels: separate starter and house battery banks
  • Caravans and motorhomes: charging auxiliary batteries while driving
  • 4WD and off-road vehicles: powering winches, fridges, and camping accessories
  • Commercial vehicles: maintaining separate battery systems for equipment
  • Off-grid solar systems: combining multiple charge sources without back-feed

Installation Considerations

When installing a diode battery isolator, it is important to account for the slight voltage drop across the diodes. The integrated compensation diode can be used to adjust the alternator’s voltage regulator, but in some systems, additional wiring modifications may be required. For optimal battery health and charging performance, consult the Victron ‘Energy Unlimited’ book or seek advice from a qualified auto electrician or marine installer. Proper cable sizing and termination are critical to minimise additional voltage losses and ensure safe, reliable operation.

Upgrade your battery management system with the Victron 100A Battery Isolator Argodiode 100-3AC and enjoy the peace of mind that comes with Victron’s proven reliability and engineering excellence. Whether you’re outfitting a bluewater cruiser, a remote-area tourer, or a commercial fleet vehicle, this isolator delivers the performance and durability you need to keep all your batteries charged and ready.

If Your Dog Can Rip The Hood Off Your Car--This Is The Dental Toy For Him/Her
I am always curious about buying the "number one best seller" that Amazon lists in any product category. And when it's an add-on item offered at a reasonable cost, I'm even more curious. From reading the reviews, it appears that some dog owners ordered this item and were disappointed in it for a number of reasons, primarily because the 'hardness' of the toy caused dental problems. Obviously no one wants to buy a dental toy that actually causes teeth problems. However, some small breed owners must not be aware that their particular breed is subject to dental issues regardless of what toys they chew. Just off the top of my head, this type of problem often occurs with Yorkies, Chihauhaus, and Chinese Cresteds. You can use virtually any dental care method in existence and still watch your Chinese Crested's teeth fall out. So small breeds shouldn't be given tough Nylabone toys like this Dinosaur model. If you watch any dog chew on this particular toy, you will quickly notice how small his/her teeth are in relation to the toy, and you will probably be surprised by the leverage and power he/she puts into each bite. They gnaw, they gnash, they continue to work at it until those tiny teeth lose the battle against the tough Nylabone. Comparing this to human teeth, everyone knows someone who fractures/cracks a tooth somehow. That's because our front "chicklet" teeth bite down on something hard, get broken from falling on your face, getting hit in the mouth, having teeth weakened by cavities, and from not seeing a dentist/hygienist on a regular basis--usually because we're afraid of a little pain. We're always looking for relatively tough dental toys for our 182 pound Cane Corso named Dante. He tears apart any toy we buy him, usually in a matter of minutes. But this particular Nylabone Dura Chew has survived for months now. If you look at the size of his teeth, length and thickness, you will see a dog with the teeth and jaw muscles strong enough to tear the hood off your car--which is exactly what he did to our Prius. So if your dog is capable of ripping hoods off cars, this treat should be good for your pet monster. Just keep an eye on the toy so that you can toss it before it breaks down and is swallowed.

Best Nylabone Fido & I Agree
My dogs love these Dino Nylabone's. Over the years I have bought at least 30 of these nylabones for 3 different dogs. Two of which have loved the Dino shaped Nylabones the best. The third loves the nylabone daily dental bone the best but the dino is a close second. The T-Rex is their favorite but they like all dino shapes. Depending on the dog's chewing mood these have lasted anywhere from a month to 6 months before needing replacing. My super chewing husky will chew one up pretty quickly in about a month, my moderate chewing pit bull would take 3-4 months and my slow light chewing shiba inu would take 6 or more months. I typically have 2-3 chewable items per dog (it helps prevent toy hoarding and aggression) and these dino toys are always among the favorites. *These are chewing style nylabones they are not supposed to be consumed quickly as a snack or treat. I consider these like a hobby or activity for my dogs to do not something they eat or a toy they play with. Chewing is a natural part of dog behavior and is good for dental hygiene. Giving your dog items they are supposed to chew on is a good way to prevent your dog from chewing on things he isn't supposed to.* These are the white nylabone material which is a tougher material than the beige color nylabones. The white nylabones should be used for aggressive chewers. Beige nylabones are good for light chewers. The T-Rex is about 6" by 5" the Long neck is about 3.5" by 7 inches and the Stegosaurus is about 6.5" by 4" they all seem to last about the same amount of time. I can usually get them for $4-5 on amazon which makes them one of the best deals for a chewing nylabone which is another huge plus. Overall My dogs and I love the Dino Nylabones and I will buy them as long as they are made. Great Product

Dog loves it and it's very durable, but not indestructible
I have a dog with very strong jaws. She's only thirty-five pounds but she goes through most toys like they're bubblegum. Even as a small puppy, she would destroy anything and everything. By the age of five or six months we had to give up on soft and rope toys altogether, and at a year old, she is limited to only hard chews like Kong, Nylabone, etc. Even then, she destroys most of these with relative ease. She's gone through chews others have recommended as long-lasting in literally ten minutes. The only toy she has that has lasted more than a month or so is her original red Kong, which she mostly licks instead of chews. I initially bought the dinosaur for my other, less toy-murderous dog, but the power chewer quickly stole it from him. She was in love. She carried it everywhere and chewed on it constantly. I'm not sure if it's the shape or the texture she likes, or some combination thereof, but whatever the case, it instantly became her favorite. Even the most durable hard toys normally only last a few weeks with her, but her dino is going on two or three months now. It's chewed beyond recognition, all the nubs worn down, and it's very rapidly nearing the end of its life because little bits of plastic are falling off, but it still lasted far longer than most toys do. A few weeks ago I bought her a second one, in a different shape, and she's equally as enamored with it. All in all, it's not going to be indestructible if you have a power chewer, but it certainly lasts a heck of a lot longer than most!

Tough enough to Survive the big, bad CHARLIE!
I purchased this for my 80 pound yellow lab, Charlie. Charlie is a very powerful chewer. Toys typically last about 2.3 seconds in his grasp. Since Charlie's toy budget had ballooned to a point where I had to choose whether to fulfill his appetite for destruction, or pay the mortgage, I knew something had to change. This is how I came across this nylabone chew. It appeared tough enough that charlie may get at least an hour of play from this toy before it was destroyed. The price was reasonable enough that it fit within what was left of the depleted toy budget. So I bought it. Two quick days later, and the box arrived. I gave the package to Charlie, and told him it was another new toy for him to destroy. The smell of the nylabone vented through the cardboard, and he started to wag. He tore open the box and found the bone inside. At this point, he is elated. I removed the packaging and told him to go at it. That was weeks ago, and the dinosaur bone still has yet to be defeated. Sure, it is missing a few spines, and his tail is heavily chewed, but the bone is not yet destroyed. That isn't from a lack on trying on Charlie's part. He chews on the bone almost daily, and hasn't gotten tired of it yet! If you have a big dog who's toy budget is getting out of control, buy this bone! Small bits will come off here and there, so if your dog likes to eat what he destroys, keep an eye on him. However, all of the small bits that have come off Charlie's bone thus far are small enough that they should pass no problem. A great bone, and if they release similar bones in the future, Charlie will be a happy customer.

Dogs who chew will love this!
I have a puggle who chews all of the time, and she has been through a variety of Nylabone products, all of which she absolutely loved. I am a huge fan of anything Nylabone, and when I saw this one, I immediately had to get it for her because not only did it look like something she would love, but the design promotes good dental health. She has had it for a month now, and she is constantly chewing on it. Not only has it helped to keep her teeth clean, but it is much more durable than other Nylabone toys. She chews it every day, carries it around and drops it all over the place, and it has barely worn at all. I highly recommend this toy for dogs who love to chew! I do have to share one negative to this toy though.... if your dog likes you to "tug" with them for their toys, this one isn't for you. It hurts to grab and pull on it. Not much of a negative, but I want to give a fair review, so if you are looking for a strong tug toy, go with a smooth surfaced large Nylabone and save your hands some pain :)
