Victron Battery Indicator Eyelet: Real-Time Battery Monitoring for IP65 Blue Smart Chargers

Stay Informed with At-a-Glance Battery Status

The Victron Battery Indicator Eyelet provides a simple yet effective way to monitor your battery’s state of charge when using a Victron Blue Smart IP65 Charger. Designed for permanent connection to your battery via M8 eyelet terminals, this accessory integrates a tri-colour LED status module that displays green, orange, or red to indicate voltage level, so you always know your battery’s condition without needing a multimeter or opening the battery box.

Ideal for caravan, marine, 4WD, and off-grid battery systems, this indicator helps prevent unexpected battery depletion and extends battery life by encouraging timely recharging. The inline 30A ATO fuse adds a layer of circuit protection, while the IP65-rated weather-resistant construction ensures reliable operation in dusty or wet environments.

Key Features

  • Tri-colour LED battery indicator — green, orange, and red lights give instant voltage status at a glance
  • M8 eyelet connectors — secure, permanent attachment to battery terminals for continuous monitoring
  • 30A ATO fuse — integrated fuse holder with weather-resistant cap protects the circuit
  • Quick-connect charger port — plugs directly into Victron Blue Smart IP65 chargers for hassle-free setup
  • IP65 protection — dust-tight and water-jet resistant, suitable for engine bays and exposed installations
  • Low back-current drain — draws just 0.9 mA, so it won’t flatten your battery over time
  • Compact design — small footprint (22 x 18 x 55 mm) fits neatly in tight battery compartments

Engineered for Reliable Battery Awareness

Unlike generic voltage meters that require separate wiring or displays, the Victron Battery Indicator Eyelet is purpose-built for the Blue Smart IP65 charger ecosystem. The 0.3 m cable with 3.3 mm² (AWG12) conductors handles up to 30 A maximum current, making it suitable for most 12V battery setups. The LED module clearly indicates battery voltage: green for healthy, orange for moderate, and red for low, helping you decide when to recharge before damage occurs.

This indicator solves the common problem of not knowing your battery’s state of charge when a charger isn’t connected. It reduces the risk of deep discharge, which can permanently damage lead-acid and lithium batteries, and eliminates the guesswork of manual voltage checks. The M8 eyelets (approx. 5/16" ring terminals) fit standard battery posts, and the 30A ATO fuse provides overcurrent protection that generic indicators often lack.

*Note: Maximum current rating is 30 A; typical de-rating factors apply for continuous loads and elevated temperatures.

Simple Installation, Immediate Feedback

Installation is straightforward: connect the M8 eyelets to your battery terminals, plug the quick-connect lead into your Victron Blue Smart IP65 Charger, and the LED module immediately begins reporting battery voltage. The weather-resistant design means you can mount it in engine bays, battery boxes, or under-bonnet areas without concern for moisture or dust ingress.

Whether you’re maintaining a deep-cycle battery in a caravan, a marine battery on a boat, or a secondary battery in a 4WD, this indicator gives you confidence that your battery is ready when you need it.

Add Confidence to Your Charging Setup

Pair your Victron Blue Smart IP65 Charger with the Battery Indicator Eyelet and take the guesswork out of battery maintenance. Order today to keep your battery health visible and your adventures on track.

YEOSEN 3 Temperature Mug Warmer
Color: Black
Wow! There really are warmer mug warmers than lukewarm! This is one of them. Who wants lukewarm coffee? The YEOSEN 3 Temperature Mug Warmer on the MEDIUM temperature setting keeps my coffee HOT enough. Not lukewarm, or barely warm (even at the bottom of the cup). In fact, I use the lower temp. settings, while the level of liquid goes down. The lowest temperature is HOT enough ...not lukewarm. It's not burning, but HOT. I bought it because the reviews said it kept the coffee much warmer than lukewarm. And it does. The point is, when I walk away from my desk for 15 minutes, the temperature of my coffee is still satisfyingly hot. After all, what is lukewarm? It's a few degrees above normal body temperature! 137 is hotter than that! The unit automatically shuts off (the Off-On button is on the bottom of the unit positioned under the hot plate and the weight of the cup pushes the button to turn it on), when you pick up the cup it shuts off. I don't like the auto shut off button on the bottom of the unit. It shuts off and on every time you take a drink. Lift the cup up and it shuts off, set it back down and it turns back on. Wish you could shut that feature off. A piece of tape? but unplugging it from the wall is inconvenient. Maybe, because it's so much warmer than lukewarm, it needs some kind of safety feature. But, all in all, I would definitely buy another one.

BEST mug warmer
Color: Black
This is the best of the many mug warmers available online. It has 3 temperatures. I use the highest - 167 degrees. I like my coffee HOT. With this warmer I don’t have to return to the microwave as often to reheat my coffee. It is very easy to use- takes large mugs as well as regular sized cups. I have looked everywhere for a “flat bottomed” mug . All the mugs I have found have a rim on the bottom which prevents complete contact with the warmer. However the warmer works with the “bottom rimed “ mugs. I use my warmer for the end table by my recliner. I am considering purchasing a second warmer for my desktop. I definitely recommend this as the BEST mug warmer. I have been using it many hours daily for over a month as I am retired. It works fine. I did just purchase a second one. It came the day after I ordered it. Now I can enjoy a hot beverage by my recliner or on my desktop. I purchased a silicone cover/lid for my mug. This really keeps my beverage hot. However when you remove the lid the condensation on the underside of the lid drips. I keep a paper towel/napkin close by to catch the condensation.

Warming Up to My New Mug Warmer
Color: Black
I keep mine next to my computer monitor so I always have that quick caffeine jolt nearby. The three temperature settings are convenient and the LED readouts ensure your brew is as hot as you want it to be. Not sure about reviews saying this warmer makes drinks lukewarm because it doesn't. In fact, it can be used to reheat drinks in just a few minutes. I also like that it's a 120v plug-in and it's not the weak, slow, and temperamental USB powered one. One tip: The on-off switch is on the underside of the warmer. It must be depressed for it to power on. If the red LED doesn't indicate the temperature, then the warmer is not on (or the button is broken). You don't have to turn the unit over either to press the power button, just press down on your mug until the temperature LED turns on. The other hint is that this warmer can get very hot very quickly. While the edges stay cool to the touch, never touch the outlined hotplate area or you might get burned. Wait for it too cool down or use a pair of oven mitts---it's that hot.

Almost started a fire
Color: Black, Color: Black
This item malfunctioned, a stack of papers about five pages was accidentally placed on top of it, and nearly started a fire. there should not be any heat from this unless there’s something having enough weight engage the heat plate. The paperwork was accidentally set on top of the hot plate, but definitely not heavy enough to engage, and the heat plate is no longer working unless I push down with my hand, a coffee cup is not heavy enough to engage it now so something has malfunctioned . I purchased this last spring and I am no longer eligible for a replacement or refund and just about burned down my office
