Reliable multi-battery charging without cross-discharge

The Victron Argo FET 200-2 Battery Isolator (200A) is a high-efficiency battery isolator designed to charge 2 battery banks from a single alternator or a single-output battery charger—while keeping each battery electrically separated. That separation is the key benefit: powering lights, a fridge or a winch from your auxiliary battery bank is far less likely to flatten the starter battery, helping improve vehicle reliability for touring, marine and off-grid power setups across Australia.

Unlike traditional diode splitters, this unit uses FET isolator technology to minimise voltage drop. In practical terms, more of your alternator’s output reaches your batteries, which can support better charge acceptance and shorter run times in real-world systems. It also avoids the common need to raise alternator voltage to compensate for isolator losses—particularly helpful when you’re integrating modern battery chemistries or managing longer cable runs.

Designed for touring, marine and off-grid electrical systems

This isolator suits common 12V and 24V automotive and marine power systems with 12/24V auto-ranging operation. It’s a strong fit for caravans, 4WD dual-battery installs, work utes, boats, and remote power cabinets where you want straightforward alternator charging distribution without tying battery banks together. Each output is independently isolated, so different battery banks can be charged simultaneously while remaining protected from mutual discharge paths.

Helps alternators start charging when split charging is installed

Some alternators require a sense/return voltage on the B+ output to begin charging. When an isolator is installed, that return path can be reduced—occasionally leading to delayed or no alternator start-up. This unit includes an alternator energise input to assist with alternator excitation in these scenarios, supporting stable charging behaviour when the engine run/stop circuit is engaged. This is particularly relevant in modern vehicles and certain marine alternator configurations.

Installation notes that protect performance

As with any high-current battery isolator, overall charging performance depends heavily on cable sizing, connection quality and cable length. Keeping cable runs short and selecting an appropriate conductor cross-section helps reduce voltage drop in the wiring so the benefits of low-loss FET switching are preserved. For best results, follow Victron wiring guidance and use properly crimped lugs, secure fasteners and sound corrosion protection—especially in coastal and marine environments.

Key features

  • Simultaneous charging of 2 battery banks from one alternator or charger
  • FET technology for very low voltage drop compared with diode splitters
  • Battery bank isolation helps reduce the risk of draining the starter battery from auxiliary loads
  • 12V/24V system compatibility with auto-ranging operation
  • High-current terminals for secure connections in demanding automotive and marine installs
  • Status indication to support quick checks during commissioning and fault-finding

Very low voltage drop (typically around 0.02V at low current, averaging about 0.1V at higher currents) helps maximise charging voltage at the batteries compared with diode isolators.

Alternator energise input can assist alternator start-up in systems where the alternator needs B+ voltage present to begin charging.

Build a more dependable dual-battery or multi-battery system

If you’re planning a dual-battery split charging system and want a proven way to distribute alternator charging while keeping battery banks isolated, the Victron Argo FET 200-2 Battery Isolator (200A) is a practical, low-loss solution. Add it to your setup to support cleaner power management and more confident starts on the road or at sea.

The "comic book" of my youth grows up.
Format: Paperback
Hey, you've got to love these new "Graphic Novels" of the present day. Way back in the day of he 1950s and 60s, I used to scoop up change wherever it was left laying about( no, not service tips and I didn't steal from my family or friends, but I always saved the change and kept it when it was ok...) I could go to the news stand and for a dime or less, all of the DC comic heroes were mine...and Sgt. Rock, the Haunted Tank, Gunner and Sarge( BUDDA- BUDDA) , were all mine too. Art work was great, stories good to....to a kid and it seem to more than a few adults too. I remember the shock when the costs went to 12 cents...then to 15 cents...then girls and life came along and the comics stayed in boxes in the basement. But the comic book survived. Now they are larger, better printed, perfectly bound with stiffer covers...and a bit more costly..but worth it. And there's a myriad of novels to select from. So I'm collecting comics again, it seems. And the term " comics" does not apply any longer, if it did back in the day! No comedy in these stories told now..."graphic" is a better description...but not lurid or extreme as the old " pre- code comics" were. This graphic novel is the story of the Allied forces and their endeavors from June 5 through early August 1944, the Normandy Campaign. It's in full color and GRAPHIC detail of the carnage faced by the line soldiers of both sides in battle. Historically it's right on the button for dates, locations, quotations, etc. Equipment is shown correctly in version, color and useage. The historical events are explained so that anyone of any age who can read will learn and be entertained. Bach in my day ( here we go again), there was a series on comics of this same nature put out by Dell Publishing on WWII historical events. Detail, color, etc. just as we have in this modern publication, but in a smaller size. The Bataan Death March, Pearl Harbor, John Kennedy and PT-109 , and so on we're a few of those topics..boy, I wish Mom hadn't cleaned out the box I had of those... I even recall the artist who illustrated most of those comics, a Navy destroyer veteran named Sam Glanszman. The illustrators of this book are in the same league as Sam! Don't miss this one. If more military history is to be done in this format, they've got my pocket change !

An interesting and detailed graphic novel that tells the story of the Normandy invasion.
Format: Paperback
One of the most important battles of World War 11 was D-Day. This excellent illustrated graphic novel covers the Normandy invasion in more detail than I expected. The main generals and other important figures are mentioned in this book. The decisions that were made which turned the battle for the Allied forces are explained, as well as Hitler's mistake of not listening to his Generals makes this book a great read. The book is organized into fifteen chapters. They are as follows: Chapter (1) Second Front Now. (2) How peaceful the land looked. (3) Hitting the beaches. (4) Blooding Omaha. (5) The skin of their teeth. ((6) The tigers of Villers-Bocage. (7) Death in the Hedgerows. (8) The devil's children. (9) The capital of ruins. (10) Blood and thunder. (11) The cobra strikes. (12) "Come and get us!" (13) Third army rampage. (14) The killing ground. (15) :Aux barricades!" In conclusion, this beautifully illustrated graphic novel will be of interest to anyone who desires a brief overview of this important World War 11 battle, which was the turning point in the war. It may motivate readers to seek out more detailed information on the Normandy invasion. Rating: 5 Stars. Joseph J.

This one's in color
Format: Paperback
This book was glorious. It presented the invasion vividly. The Allied forces sure kicked Rommel's butt, and although the American forces had many casualties, the Germans were defeated. After the Allies liberated France, people revealed hidden Tri-Color French flags. I was interested to learn about the problem of French hedgerows and how an American sargent (Curtis Cullin) improvised a brush-cutter out of the beach barricades in order to leave the tanks less vulnerable as they crossed the fields. Thank you Curtis! The book also talked about a German tank commander named Michael Wittmann and his Tiger tank. This was a powerful weapon that destroyed a group of Shermans very quickly and then took out part of a convoy. The allies finished him off by using British Fireflies (a British type of tank) that sent a disabling shot into the tank. Michael Wittman and his crew escaped. There was good tank action in this book. It feels like you're stuck in the middle of battle, but you're safe. But you're watching in horror. The drawings of the Avro Lancasters were really great. That's my favorite British plane. The air war made the difference in the invasion's success. If it weren't for the RAF and the Allied air forces, the invasion might not have succeeded. I'm eleven years old, and this is a really good book. I learned a lot. This book had really good maps, and it was in color. That helped me a lot. The blood was not too bloody -- just scribbles. Parent note: my son says blood and guts included.

Great read for a WWII enthusiast
Format: Paperback
Purchased for my nephew who is 11 and a WWII aficionado, "Bombing Nazi Germany" and "Normandy" did not disappoint. While I got him the graphic novels because he is a visual kid, he really enjoyed the text. Which is good because there is a lot of text. I am an avid reader of graphic novels and found these books to be more text-driven than much of what I've read. That said, the prose is solid, unadorned, and moves the narrative smoothly from pane to pane. I recommend this for anyone fascinated by war histories who also values detailed illustrations of the same.

I wish my Dad had lived long enough to have this given to him!
Format: Paperback
As I said for Mr. Vansant's Gettysburg graphic novel, this is perhaps the best visual description of all of the planning, logistics, and follow-up battles that gave the Allies their second front, and began the march to Berlin, and the eventual downfall of Hitler's Thousand Year Plan. I have studied War History for as long as I can remember - focusing mostly of the American Civil War, World War 2, and Vietnam; three of the United States' greatest turning points in warfare - but my Dad and I shared a huge interest in WW2, watching as many documentaries on it as we could. What most people do not know about the importance of the war is that it is one of the few times that most of the world was not only involved either directly or indirectly, but also it is one that everyone - and I mean everyone, from the footsoldiers, leaders, and civilians - knew exactly why and what they were fighting for. While it seems odd to refer to events so brutal as noble, that is the best way to describe World War 2, since most of the world was involved in it, and why.
