Reliable multi-battery charging without cross-discharge

The Victron Argo FET 200-3 Battery Isolator is a high-efficiency battery isolator designed to charge 3 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 3 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 3-battery split-charging system and want a proven way to distribute alternator charging while keeping battery banks isolated, the Victron Argo FET 200-3 Battery Isolator 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.

wasting your money
Size: 35 x 7, Color: White-rgb
I’m very disappointed with this purchase. The shelves have a questionable finish - honestly, you can get something cheaper and much better quality at IKEA. But the biggest issue is the lighting. None of the lights work. I put in brand-new batteries and absolutely nothing happens. I wouldn’t recommend wasting your money on this product.

Lights stop working after a few usage
Size: 31 x 7, Color: Black-rgb
I had these shelves for a few months now. The shelves are great and are very easy to install. I also like that they offer different sizing, so depending what you are storing on them. They can fit a lot of items and are sturdy so you don’t have to worry about it falling. The lights were amazing at first and the main reason why I bought this product, but after a few times using them they stopped working completely and no longer connect.

Incomplete kit. Missing anchors. LED are white not yellow or amber. Shelf is dented. Had to buy double sided tape for the LEDs to stick. Strips can't hold weight of charging blocks. Not easy to install

Highly recommend

I absolutely love the look of this coffee and beverage station. The purple LED lighting creates a modern and inviting atmosphere, while the neatly organized syrup bottles and glassware give it a professional café-style appearance. The variety of flavored syrups offers plenty of options for customized drinks, and the clean white shelving makes everything easy to access and visually appealing. The setup feels both elegant and functional, making it perfect for serving specialty coffees, lattes, and other beverages. The decorative touch on the upper shelf adds personality and style, creating a welcoming space for customers or guests. Highly recommended for anyone looking to create a premium coffee experience! ☕✨

Fabulous!
Size: 65.6ft, Size: 65.6ft
I have wanted some strip lights for soo long! I absolutely love these! Great quality! The adhesive is very strong and keeps the lights tight against the wall. Even with bumpy paint there was no issue with it sticking. The colors are fabulous, so many to choose from. Set up is very easy. Pull off the sticky tape and press where you want the lights to go. I have had no trouble with Bluetooth connecting. I run the lights through the app and it connects easily and quickly. There is such a variety of light themes to play with and set moods. This stip can be cut. I made sure to do it right down the middle of the copper lines. I recommend turning the lights off, making the cut, and then turning the lights back on again. What is cut off will not work. I had a bit extra that I cut off and the two ends overlap a little, but it's hardly noticeable if you stare real hard. These lights are so awesome! I highly recommend. Also it is so great to be able to turn up and down the brightness!
