Victron 180A Battery Isolator Argodiode 180-3AC: High-Efficiency Schottky Diode Battery Isolator for Dual and Multi-Bank Charging

Reliable Simultaneous Charging Without Battery Interconnection

The Victron 180A Battery Isolator Argodiode 180-3AC 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 180A Battery Isolator Argodiode 180-3AC 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 180A Battery Isolator Argodiode 180-3AC 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 200 mm—and light weight of 1.5 kg make installation straightforward in tight engine bays or electrical compartments. Heavy-duty M8 stud terminals (Approx. 5/16") 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 M8 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 180A Battery Isolator Argodiode 180-3AC 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 180A Battery Isolator Argodiode 180-3AC 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.

Arthurian Fae Quest…say less.
Format: Kindle
A fae centered Arthurian tale unlike any I’ve read so far. The author did a great job at descriptive world building, with scenes easily playing out in my minds eye. There was plenty of action, suspense, and even a touch of horror. An enemies to lovers, slow burn romance, a quest, with plot twist and turns aplenty. There was a love triangle, which I’m not usually a fan of but, it played out well in this story line. The FMC, Morgan Pendragon, was so blatantly naïve, yet I typically expect as much in a ‘book one’ of a series, especially one that features a fairly sheltered princess. I was happy to read that in spite of this, she still showed a strong sense of morals, fire, and spine. Now our MMC? Kairos Draven, aka Void’s Edge. Oh, how I’m a sucker for a smoking’ hot grumpy warrior alpha with a witty mouth, and a strong sense of “touch her and die” attitude, so you know who held all my cards. That ending? Just made me swoon all the harder. Now add a battlecat that rivals the size of a horse…and well Ms. Briar Boleyn you have well and truly stolen my heart. I’m excited to see where the story goes from here, and follow along to see more of the characters growth. I went into this story fairly blind, and I think I enjoyed it all the more because of it. Once the story got going, it had me in an absolute chokehold and it was difficult to put down.

Not a bad start
Format: Kindle
3 stars Thank you Netgalley and Briar Boleyn for the ARC! A camelot/king Arthur retelling with fae. I was hooked by the idea of this book immediately and was eager to jump into this world. • slow burn • enemies to lovers • who did this to you Morgan Pendragon watched her mother die by her father's hand when she was just eight years old, hiding under the bed. Morgan is believed to have the tainted blood of the fae in her veins and is cast aside so that her fathers illegitimate son, Arthur, can become the king. She's seen his cruel treatment of the fae firsthand, so when he sends her on a journey to find a fae weapon she seizes the opportunity to do more with her life. Along the way, she finds more than she could have imagined. I don't know a whole lot about King Arthur and Camelot but I had a lot of fun with this story! The plot has some similar tropes to popular romantasy books (From blood and ash) but there's enough originality here that it doesn't feel like I'm reading a copy. I liked how the fae were different in appearance than what is typical in most fantasy books I've read. In this book they have blue hair, violet skin and a wide range of other characteristics. I thought that the world building was easy to follow and I could easily immerse myself into this world. After reading the blurb I kept wondering when she was going to go on the journey to find Excalibur and it doesn't happen until around the 45% mark. The story is a bit slow at times but starts to pick up once they begin their journey to find Excalibur. The John Wick style Inn was a fun concept that I enjoyed reading about. There are a lot of similarities to this and FBAA and I would have liked to have it be a little more different, but I'm hoping book two will have the story turn into something of its own. Overall I enjoyed reading this story and I'm looking forward to reading book two especially after that ending.

Right from the start, I was drawn in by the prologue!!!
Format: Paperback, Format: Paperback
Queen of Roses (Blood of a Fae #1) by Briar Boleyn Genre General Fiction ( Adult), Romance, Sci-Fi & Fantasy, Dark Romance “More primordial than the stars. My name was on his lips as he promised unspeakable darkness to any who came between us.” Right from the start, I was drawn in by the prologue!!! I’m a big fan of “touch her, and you die” vibes, but I mean, what’s also not to love about a unique Arthurian retelling with gender twists, a treacherous royal court, a dangerous quest, magical Fae & mystical monsters, entwined with a bit of spice! Morgan, Princess of Pendrath and true heir to the throne has spent most of her life dimming her light to feel safe and to make others comfortable. She is treated as an outcast in the court and repressed by her family due to the blood of the Fae within her and forced to join the Temple of the Three as a priestess in training to one day replace Merlin. Her brother, King Arthur, who reminds me of Joffrey from Game of Thrones, later tells her that he has other plans and offers her a choice of the Temple or to marry her off for political gain, unless… that is, she can journey through the great unknown and return with a long-lost fae weapon with enchanted powers known as Excalibur. Her quest begins with a roguish crew that includes the mysterious, arrogant, and heart-tuggingly handsome Captain of the Royal Guard, Kairos Draven, whom she can’t decide if she wants to stab or indulge in pleasure with. Along the way are plenty of surprises, mystical creatures, and betrayal, all while Morgan uncovers more of the truth about herself and who she can trust. This book had intriguing storylines and lovable characters that kept me turning pages and wanting more. I can’t wait to see how it all unfolds and comes together in book 2, Court of Claws, which I just started reading!! Read if you’re into- Dark Fantasy/Romance Slow–Burn Question Everything Magic and Action Fae Arthurian Legend Stabby/Broken FFC Morally Gray MMC Forced Proximity Queen of Roses is perfect for Holly Black, Jennifer L. Armentrout, and Sarah J. Maas fans. Please check the trigger warnings page in the table of contents before reading this book.

3.5 stars, A little boring to say the least.
Format: Kindle
Wow so I'm not sure where to begin on this one. This was a very different take on the legend of Arthur and Excalibur. This is told from the point of view of Morgan the sister of Arthur. Honestly the first 50% of this book is world building and character building which unfortunately was super boring for me. Morgan to me was a female MC that had a hard time in believing in herself. Sometimes taking too long to understand exactly what was going on around her. Draven was also a different male MC, like I couldn't put my finger on him and what he was all about. It was not until the last 10% of the book did we get some answers on the mystery that is Draven. The other 50% of the book centered around this big journey with everyone having a different motive. We see a spark of magic around this time that had me excited but then we never expanded upon that and what it could mean for the female MC. I feel like I want to read the second book just to see where this goes, but the spice was probably a 2 out of 5. Side characters are ok, Lancelet was fun but I almost felt like I wanted more.
