{"product_id":"victron-battery-indicator-eyelet-m8","title":"Victron Battery Indicator Eyelet","description":"\u003cp\u003eThe Victron Energy Battery Indicator Eyelet M8 is a compact, easy-to-use battery state of charge indicator designed as an accessory for the Blue Smart and Blue Power IP65 charger range. Suitable for 12V lead-acid batteries — including flooded, GEL, and AGM types — it provides an instant visual indication of battery charge level via a three-colour LED, allowing users to assess battery condition at a glance without connecting a charger or battery monitor.\u003c\/p\u003e\n\u003cp\u003eThe eyelet connects directly to the positive battery terminal via its M8 eyelet connector, with a 30A ATO blade fuse built into the cable to protect the circuit. A short 0.3-metre cable keeps the indicator close to the battery terminal where it mounts permanently — ideal for installations in engine bays, battery compartments, and under-seat battery locations in cars, boats, motorhomes, and caravans where a fixed, always-visible charge indicator is needed without panel cutout or dashboard installation.\u003c\/p\u003e\n\u003cp\u003eThe three-colour LED display provides a clear, graduated indication of battery state of charge: green indicates the battery is well charged at 80–100%, orange indicates the battery can be charged at 60–80%, red indicates the battery needs charging at 40–60%, and no light signals that the battery is critically low below 40% and should be charged immediately to prevent sulfation damage. After use, a settling time of approximately 30 minutes is recommended before reading the indicator to allow the battery to return to its resting voltage for an accurate state of charge reading.\u003c\/p\u003e\n\u003cp\u003eIP65-rated against dust and water splashes, the Battery Indicator Eyelet M8 is built to withstand the damp, dirty environments commonly found in marine bilges, outdoor equipment, and engine compartments. With a back current drain of just 0.9mA, it draws negligible standby current from the battery and can remain permanently connected without causing measurable self-discharge over normal storage and standby periods.\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003ch4\u003eThree-Colour LED Battery State of Charge Indication\u003c\/h4\u003e\n\u003cp\u003eA single LED displays battery charge level across four clear states: green (80–100%, charged), orange (60–80%, can be charged), red (40–60%, needs charging), and no light (below 40%, charge immediately to prevent sulfation). This provides an instant, easy-to-read indication of battery health without any buttons, settings, or additional equipment.\u003c\/p\u003e\n\u003ch4\u003eDirect M8 Eyelet Terminal Connection\u003c\/h4\u003e\n\u003cp\u003eThe M8 eyelet connector fits directly onto the positive terminal bolt of any standard lead-acid battery, providing a secure and permanent mechanical connection with no loose plugs or clips. The compact 0.3-metre cable keeps the indicator body close to the terminal for a neat installation in confined battery compartments.\u003c\/p\u003e\n\u003ch4\u003eIntegrated 30A ATO Blade Fuse\u003c\/h4\u003e\n\u003cp\u003eA 30A ATO blade fuse is built into the cable between the eyelet terminal and the indicator, providing overcurrent protection for the circuit without requiring any additional fuse holder, fuse block, or wiring components — keeping the installation simple, clean, and safe.\u003c\/p\u003e\n\u003ch4\u003eIP65-Rated — Built for Demanding Environments\u003c\/h4\u003e\n\u003cp\u003eThe IP65 protection rating provides full resistance to dust ingress and water splashes, making the Battery Indicator Eyelet M8 well suited to marine bilge environments, outdoor equipment boxes, engine compartments, and other installation locations where moisture and dirt are unavoidable.\u003c\/p\u003e\n\u003ch4\u003eUltra-Low Standby Current Drain\u003c\/h4\u003e\n\u003cp\u003eWith a back current drain of just 0.9mA, the Battery Indicator Eyelet M8 can remain permanently connected to the battery terminal without causing meaningful self-discharge — drawing less than 22mAh per day, which is negligible compared to the self-discharge rate of any standard lead-acid battery.\u003c\/p\u003e\n\u003ch4\u003eCompatible with Blue Smart and Blue Power IP65 Charger Range\u003c\/h4\u003e\n\u003cp\u003eDesigned specifically as an accessory for the Victron Blue Smart IP65 and Blue Power IP65 charger range, the Battery Indicator Eyelet M8 complements the charger's DC connector accessories and provides permanent at-a-glance battery monitoring when the charger is disconnected — closing the loop between charging sessions.\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003ctable class=\"product-spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Battery Voltage\u003c\/td\u003e\n\u003ctd\u003e12V lead-acid (flooded, GEL, AGM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage Range\u003c\/td\u003e\n\u003ctd\u003e6-15V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Current\u003c\/td\u003e\n\u003ctd\u003e30A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse\u003c\/td\u003e\n\u003ctd\u003e30A ATO blade fuse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBack Current Drain\u003c\/td\u003e\n\u003ctd\u003e0.9mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Length \/ Diameter\u003c\/td\u003e\n\u003ctd\u003e0.3m \/ 3.3mm² (AWG12)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Class\u003c\/td\u003e\n\u003ctd\u003eIP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.37 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (H x W x D)\u003c\/td\u003e\n\u003ctd\u003e0.87 × 0.71 × 2.17 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eManuals\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.victronenergy.com\/upload\/documents\/Manual-Battery-indicator-panel-\u0026amp;-Indicator-Eyelet-EN-NL-FR-DE-IT-ES-SE-TR.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47127247159545,"sku":"BCV51035","price":18.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/8538\/1625\/files\/Product-BCV51035-2.webp?v=1778823058","url":"https:\/\/emarineinc.com\/products\/victron-battery-indicator-eyelet-m8","provider":"eMarine","version":"1.0","type":"link"}
