Heavy-Duty Circuit Protection for Off-Grid and Mobile Power Systems

The 5-Pack of Victron 500A 80V MEGA Fuses provides critical overcurrent protection for demanding electrical setups. Unlike generic plastic alternatives, this fuse utilises a robust ceramic housing that withstands extreme heat and electrical faults without deforming. This ensures maximum safety for your battery bank and connected equipment, keeping your power systems secure in harsh Australian environments.

Optimized for 12V, 24V, and 48V Applications

With a maximum DC voltage rating of 80V, this fuse is perfectly suited to a wide variety of modern off-grid and mobile systems. Whether you are running a standard 12V automotive setup, a 24V marine configuration, or a high-capacity 48V solar battery bank, it delivers consistent and reliable protection. The high voltage overhead significantly reduces the risk of dangerous electrical arcing during a blown fuse event, which is a critical safety factor when dealing with high-capacity lithium battery banks.

Built for Durability and Secure Connections

Mobile and industrial environments expose electrical components to constant vibration and thermal cycling. Engineered with standard M8 compatible bolt-down terminals and a 50.8mm mounting hole centre distance, this fuse provides a secure, vibration-proof connection that will not loosen over time. This prevents high-resistance joints, reduces heat generation, and maximises overall system efficiency.

  • Ceramic Insulation: Highly heat-resistant body prevents melting and enhances structural integrity during extreme overcurrent events.
  • Vibration-Proof Mounting: Bolt-down M8 terminals ensure long-term, low-resistance connections in mobile environments like caravans and boats.
  • High DC Voltage Rating: Safely interrupts fault currents across multiple voltage platforms without hazardous arcing.
  • Convenient 5-Pack: Provides immediate spares to keep your vital systems operational during unexpected electrical faults.

Precision Engineered for System Efficiency

Efficiency is critical in DC power systems. This fuse is strictly calibrated to maintain an exceptionally low cold resistance, meaning it produces minimal voltage drop across the connection during normal operation. This ensures your inverter, charge controllers, and DC appliances receive the maximum available power from your battery bank without unnecessary energy loss being dissipated as heat.

Mitigating Risks in High-Current Circuits

A short circuit in a high-capacity battery system can release an immense amount of energy in milliseconds, potentially causing severe damage to surrounding components. Installing the 5-Pack of Victron 500A 80V MEGA Fuses directly at the battery terminal or major busbar distribution point safeguards your expensive wiring and power electronics. By interrupting the circuit instantly when the current exceeds its rating, it isolates the fault well before thermal damage occurs.

Versatile Applications Across Industries

These high-current MEGA fuses are an essential safety component for a wide range of DC electrical projects. They are routinely deployed in:

  • Caravan and camper trailer dual battery systems
  • Marine battery banks and high-draw electric winches
  • Off-grid solar energy storage and inverter-charger installations
  • 4WD power distribution and auxiliary power setups

Ensure your electrical system is protected by professional-grade hardware. Order the 5-Pack of Victron 500A 80V MEGA Fuses today to secure your power system with reliable, heat-resistant circuit protection.

Leaking mattress 2nd use, Good Warranty Help, Bag not durable
Style: 22", Color: Grey, Size: Queen
UPDATE: first time I slept alone, all was good. Our second week to use, we were past the warranty. Tried to sleep on it with two people and it's deflating. I don't believe it's the weight because it deflates when no one is using it as well. Contacted company, they are very helpful, and I believe you're speaking to someone in the US. You can remove the pump and there's a gasket that you can try to snug up. That did not help so they are shipping a new mattress to me. Removed star because bag already had hole at seam when delivered, and it's not durable. I'll contact the company and update. The bag isn't looking durable. Mattress does seem very durable. Blows up and deflates as expected. It does have a plastically smell when you first inflate, and again when I deflated. I can't complain, it's plastic lol. If smells bother you, just inflate ahead of time in another space. Deflating smell was stronger of two. Again, just deflate in another ventilated space. The mattress didn't continue to smell with use. Make sure you have deep pocket sheets. There is no indent for the bottom of the elastic to go around. I only had to fix them once in 8 nights. I slept alone, so I can't say how it would be with two. I'll update when we sleep on our with two people. But I found it very firm and comfortable. I've been having some back & neck pain. It didn't cause any problems. Might have to add some air 2nd night as the mattress might stretch a bit first time using. Found it to be true queen size. Cord/plug a little tricky to store back in the compartment within mattress. Does take some time to deflat. It folds easily and compact, but I'll have to figure out the configuration of exactly how to fold it to get it to fit into the bag once I get a replacement. I believe you'll need two people to get it in the bag. It's heavier than the thinner mattresses. So much nicer having the higher height, especially if you're going to sleep on it for more than one night. I think I went with the 22".

Quiet Inflation and Solid Comfort
Style: 22", Color: Grey, Size: Queen
I’ve been really impressed with this air mattress. The firmness is spot on—it doesn’t feel like you’re sinking or fighting to stay level like a lot of other inflatables. It actually holds its shape well enough to feel close to a real bed, which surprised me. One of the biggest things for me was how well it holds air. I left it set up for 3 days straight, and it barely lost any pressure. I only needed to top it off slightly, which is way better than most air mattresses I’ve used that need daily reinflation. The built-in pump is another win. It inflates quickly and, more importantly, it’s relatively quiet compared to others. You’re not blasting the whole house when you set it up late at night. Deflation is just as easy, which makes packing it up for storage or camping super convenient. I’ve used it both for guests and for camping, and it performs great in both situations. It’s comfortable enough that guests don’t feel like they’re getting the “temporary bed,” and durable enough to handle being moved around. Overall, this is one of the better air mattresses I’ve owned—reliable, comfortable, and easy to use. Definitely recommend if you want something that won’t let you down after the first night.

From an IDOO 18" to this Intex 22" queen air mattress
Style: 22", Color: Grey, Size: Queen
I have been sleeping on air mattresses for about 5 years now. Yes, every night. The reason is that I cannot afford a decent new mattress and before switching to an air mattress, I had used mattresses. Most developed "sink holes" and those who sleep on an older mattress know what I mean - a spring or something inside has shifted and that spot...well, it's a dip that you have to figure out how to avoid when sleeping. But the basic reason is because I am an older lady that lives alone and when I have moved, I have moved myself so as not to bother people. I have mostly flat pack furniture so I can break it down and move it myself. Having an air mattress fits right in with that ease of moving my own stuff. The IDOO I had was a great deal, though I had last had a King Coil 22" that I really liked EXCEPT for their "pillow" area (the part at the head is inclined and that bothered me since I am an "arm sleeper" - put one arm up under my pillow, under my head and hang it off the bed). Other than that part King Coil is a great air mattress bed. Now for this Intex - I have had a couple of different Intex items and find they make quality stuff - first was a smaller, rectangular pool that wasn't too hard to set up (but I did need a friend to help with putting it up) and I currently have their inflatable loveseat that unfolds to become a bed. It's a nice extra piece of furniture/bed, but wish it had the internal pump which it doesn't. Still, it is a serviceable spare seating and sleeping piece that can be put up quickly enough. NOW, for this bed - back to my 22" height and I am SO HAPPY with that part of it. When you are older, getting UP off something is harder than scooting down off that same thing! Meaning that I have no problem getting on a bed (no matter what the height), but in the morning, when I'm groggy and not 100%, trying to push myself up off the 18" wasn't horrible, but it wasn't fun at all. With this Intex 22" queen, my feet dangle just a bit off the floor and pushing myself off and DOWN is just so much easier. I was also relieved that the pump is at the top (or could be the bottom, depending on how you orient the bed) as my outlet is at that spot on the wall behind the bed. The IDOO had the pump on the side so the cord had to be put up under the bed...I didn't like that. This Intex, like all the air mattresses with an internal pump, it inflates (and deflates) very quickly. Around 5 minutes. What's easy is taking down an air mattress - most of them come with a carry case as this one did - and if you flip the sides in, then do a fourths fold up, it will fit in the bag and isn't too terribly heavy even for me to carry. The IDOO developed a leak and instead of trying to patch it, as I have slept on it for about 2 years, I deflated it, put it in the bag it came with and threw it away. This Intex, I had it out of the box an fully inflated in less than 10 minutes. Made the bed and laid down on it - aaahhhh! So, if you are in need of a spare bed for overnight guests on occasion OR you have had it with your lumpy old "regular" mattress and having sticker shock over the memory foam, purple, pillow top and other replacements, you might want to try an air mattress. Even if you only use it long enough to save enough money for one of those $500-$1000 mattress, this $75 mattress will allow you to sleep well, night after night after night.

Better than our actual mattress!!
Style: 22", Color: Grey, Size: Queen, Style: 22", Color: Grey, Size: Queen
Purchased for company to stay with us in our apartment. I honestly had no idea they made air mattresses this tall until I saw a friend with one! My husband and I tested it out last night. We were both really impressed! 1. Really easy to inflate! First time having an internal air pump. No more forgetting the pump! The motor wasn’t nearly as loud as our previous air pump! I was able to talk to my husband and he could still hear me over the pump running. 2. Really comfortable and supportive! We chose not to inflate it fully so it contoured to our bodies better. We slept on the mattress with no sheets and I wasn’t able to feel the creases in the top which was nice. No issues with sagging and we both didn’t wake up smooshed in the middle. My husband got up in the middle of the night and I didn’t notice. So movement of the mattress is minimal! Easy to get on and off with the 22” height. 3. Easy to deflate! We followed the instructions for folding and we got it in the storage bag with no issues. Just make sure all of the air is out before you fold it. 4. High quality! We had both of our small dogs on this with us. I was afraid of their nails poking a hole but so far so good! Only a little bit of air leaked out but it could’ve been the material stretching out during the night. Cons: The pump does not shut off automatically when inflating or deflating. So keep an eye on it so it doesn’t overfill. The mattress does get cold at night. My husband and I both mentioned that in the morning. I had to roll up in my blanket to stay warm. I’ll try sheets on next time. In the summer it might not be that big of an issue. Ours came with one patch. Hopefully we won’t need to use it.

Love this bed
Style: 22", Color: Grey, Size: Queen
This bed is more than what I can ask for with the built in air pump. It's firm but comfortable my guest never complained I loved the height of the one I purchased and I loved that it gives you other height options. Super easy to set up and it holds air well. Other blow up beds I've purchased over time deflated and this one is still going strong after almost two months without me having to release the air and replace it. Had a bit of an oder when I first opened it but it's gone now. So happy with my purchase.
