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.

Good Ingredients, Tasty, and Convenient
Flavor Name: Beef Sticks - Original
Grassfed and good ingredients, these beef sticks taste good and are a great snack to have on hand. I like to bring a few along when I travel since I'm gluten free and can't always find something healthy to eat on the go. I highly recommend them.

The Perfect On-The-Go Snack!
Flavor Name: Beef Sticks - Original
I’ve tried countless meat sticks, but these 100% grass-fed beef sticks are in a league of their own. They have officially become my absolute favorite snack, and I make sure to always have a stash on hand in my pantry and gym bag. ​What really sets these apart for me: ​Superior Texture: Unlike so many other brands that are dry or tough to chew, these have the perfect amount of moisture and a "snap" that isn't rubbery. ​Clean Ingredients: It’s hard to find a convenient snack made with such high-quality, grass-fed beef. You can really taste the difference. ​Low Sugar: I love that I’m getting a protein boost without the hidden sugars and fillers found in most jerky products. ​If you're looking for a quick, savory, and healthy snack that actually satisfies, look no further. Highly recommended!

Soft and delicious, but pricey (but worth it if you care about health)
Flavor Name: Venison Sticks - Original
Ugh, I wish these weren't so pricey, but I know it's because of the high-quality and I really do care about that. I'm willing to pay a bit more of grass-fed and finished meat. And these are the perfect quick snack. They're delicious, they're not hard and impossible to bite/chew like some meat sticks, and they give you clean nutrition. I didn't find them particularly greasy either. The packaging is impossible to open, but I wonder if I got a bad set - all of them are fully sealed at the top where normally there are two pieces so that you can peel the package open. All of mine require scissors to cut open which is frustrating but not the end of the world. Again, not sure if that's standard packaging or just a flaw on the ones I got. In any case, they are great and I have already repurchased!

DELISH
Flavor Name: Beef Sticks - Jalapeño
My entire family LOVES these meat sticks. You can taste the freshness. The texture is meaty, No greasy film, no nasty ingredients. I was sold after reading about the fermentation process of these meat sticks. Excellent flavor. I’ll never stop eating these. Jalapeño are my favorite, they aren’t too spicy.
