A poorly constructed shunt can introduce resistance variations that lead to incorrect current readings, causing your battery monitor to misreport state of charge. Over time, this can result in undercharging or over-discharging your expensive battery bank, shortening its lifespan. The Victron 500A\/50mV shunt uses a \u003cstrong\u003emanganin alloy resistive element\u003c\/strong\u003e, chosen for its extremely low temperature coefficient of resistance. This means the shunt maintains its calibrated accuracy even as ambient temperatures fluctuate, a common challenge in engine rooms, uninsulated battery boxes, and outdoor enclosures.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003esolid brass blocks\u003c\/strong\u003e and \u003cstrong\u003eM10 stud terminals\u003c\/strong\u003e (approx. 3\/8\"-16) are designed to accept heavy-gauge cable lugs up to 4\/0 AWG (approx. 95 mm²), minimising connection resistance and heat buildup at high currents. The separate \u003cstrong\u003eM4 sensing screws\u003c\/strong\u003e allow you to connect the voltage sense wires directly to the shunt, bypassing the high-current path. This Kelvin (4-wire) connection method eliminates the voltage drop across the main terminals from the measurement, a critical detail for accurate low-voltage monitoring in 12V, 24V, and 48V systems.\u003c\/p\u003e\n\u003ch3\u003eInstallation and Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis shunt is a direct replacement for the standard shunt supplied with \u003cstrong\u003eVictron BMV-700, BMV-702, and BMV-712 battery monitors\u003c\/strong\u003e. It is also compatible with the \u003cstrong\u003eVictron SmartShunt\u003c\/strong\u003e series when a separate 50 mV shunt is required. Installation is straightforward: mount the shunt on a non-conductive surface using the two 6.5 mm mounting holes, connect the battery negative cable to one brass block and all loads\/chargers to the other, then attach the sense wires from your BMV or SmartShunt to the M4 screws. The insulated base prevents accidental short circuits, and the compact dimensions allow placement in tight spaces.\u003c\/p\u003e\n\u003cp\u003eFor systems operating at higher voltages, this shunt is suitable for use in \u003cstrong\u003e12V, 24V, and 48V DC systems\u003c\/strong\u003e, provided the connected monitoring device supports the system voltage. The 50 mV output is standard across the Victron BMV range, ensuring plug-and-play compatibility without the need for configuration changes.\u003c\/p\u003e\n\u003ch3\u003eBuilt for Harsh Environments\u003c\/h3\u003e\n\u003cp\u003eWhile the shunt itself is not IP65 rated (the BMV or SmartShunt enclosure provides environmental protection), its robust construction with corrosion-resistant brass terminals and a durable phenolic base makes it suitable for use in marine, automotive, and off-grid environments. The large terminal surface area and secure bolted connections resist vibration and thermal cycling, common in mobile installations.\u003c\/p\u003e\n\u003cp\u003eNote: This is a passive component and does not include Bluetooth or any electronics. It must be paired with a Victron BMV head unit or SmartShunt to function as a complete battery monitor.\u003c\/p\u003e\n\u003ch3\u003eGet Accurate Battery Insights\u003c\/h3\u003e\n\u003cp\u003eEnsure your Victron battery monitor delivers the precise data you need to manage your energy system effectively. \u003cstrong\u003eOrder the Victron 500A\/50mV shunt today\u003c\/strong\u003e and maintain the accuracy and reliability of your power monitoring setup, whether on the water, on the road, or off the grid.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable class=\"product-specifications\" style=\"width:100%; border-collapse:collapse; border:1px solid #d9d9d9; table-layout:auto;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #d9d9d9; padding:8px; text-align:left; width:35%; vertical-align:top;\"\u003ePart Number\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #d9d9d9; padding:8px; vertical-align:top;\"\u003eSHU500050100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #d9d9d9; padding:8px; text-align:left; width:35%; vertical-align:top;\"\u003eShunt Rating\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #d9d9d9; padding:8px; vertical-align:top;\"\u003e500 A \/ 50 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #d9d9d9; padding:8px; text-align:left; width:35%; vertical-align:top;\"\u003eOverall Length\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #d9d9d9; padding:8px; vertical-align:top;\"\u003e121 ±1 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #d9d9d9; padding:8px; text-align:left; width:35%; vertical-align:top;\"\u003eOverall Width\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #d9d9d9; padding:8px; vertical-align:top;\"\u003e25.6 ±0.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #d9d9d9; padding:8px; text-align:left; width:35%; vertical-align:top;\"\u003eOverall Height\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #d9d9d9; padding:8px; vertical-align:top;\"\u003e35 ±1 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #d9d9d9; padding:8px; text-align:left; width:35%; vertical-align:top;\"\u003eMounting Hole Diameter\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #d9d9d9; padding:8px; vertical-align:top;\"\u003eØ 6.5 mm (2x)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #d9d9d9; padding:8px; text-align:left; width:35%; vertical-align:top;\"\u003eMounting Hole Centres\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #d9d9d9; padding:8px; vertical-align:top;\"\u003e101.8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #d9d9d9; padding:8px; text-align:left; width:35%; vertical-align:top;\"\u003eTerminal Studs\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #d9d9d9; padding:8px; vertical-align:top;\"\u003eM10 x 15 (2x)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #d9d9d9; padding:8px; text-align:left; width:35%; vertical-align:top;\"\u003eSide Screws\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #d9d9d9; padding:8px; vertical-align:top;\"\u003eM4 x 6 (2x)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Victron","offers":[{"title":"Default Title","offer_id":52364418187547,"sku":"VIC-SHU500050100","price":33.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0854\/3354\/9083\/files\/VIC-SHU500050100-01.jpg?v=1781659142","url":"https:\/\/www.nbcampingequipment.com.au\/products\/victron-shunt-500a-50mv","provider":"NB Camping Equipment","version":"1.0","type":"link"}
