{"product_id":"renogy-battery-voltage-sensor-with-m8-ring-terminals","title":"Renogy Battery Voltage Sensor with M8 Ring Terminals","description":"\u003cp class=\"product-lead\"\u003eThe Renogy Battery Voltage Sensor (BVS) is a 16.4 ft (5 m) accessory cable that delivers a more accurate voltage reading from the battery terminals directly to a compatible Renogy charge controller or DC-DC MPPT charger, allowing the controller to regulate charging stages more precisely. It supports 12V, 24V, 36V, and 48V battery banks and works with lead-acid (Flooded, Sealed, and Gel) and lithium iron phosphate chemistries.\u003c\/p\u003e\n\n\u003ch2\u003eAccurate Voltage Where It Counts\u003c\/h2\u003e\n\u003cp\u003eIn systems with long wire runs between the charge controller and the battery bank, voltage drop along the cable can cause the controller to read a higher voltage than what actually exists at the battery terminals. When the controller acts on that inflated reading, it may exit bulk or absorption charging too early, leaving the battery undercharged over time. The Battery Voltage Sensor connects directly to the battery terminals and sends the true terminal voltage back to the controller, so charging stage transitions happen at the right moment rather than based on an inaccurate measurement at the controller's own terminals.\u003c\/p\u003e\n\n\u003ch2\u003eWorks Across Multiple Controllers and Battery Types\u003c\/h2\u003e\n\u003cp\u003eThe Battery Voltage Sensor is compatible with several Renogy MPPT and PWM charge controllers: the Rover 60A\/100A (via the \"Battery Sampling\" port), the Rover Boost 10A and Rover Elite 20A\/40A (via the \"BATT\" port), and the Adventurer Li 30A (via the \"Batt Remote\" port). It also works with Renogy 30A and 50A DC-DC MPPT battery chargers via the \"BVS\" port. Battery compatibility spans 12V, 24V, 36V, and 48V banks, including all Renogy Lithium 12V\/48V, AGM 12V, and GEL 12V batteries, as well as flooded and sealed lead-acid types.\u003c\/p\u003e\n\n\u003ch2\u003eThree-Step Installation\u003c\/h2\u003e\n\u003cp\u003eInstalling the Battery Voltage Sensor does not require special tools. First, connect the red wire to the positive pin and the black wire to the negative pin of the green terminal block, tightening the screws with a screwdriver. Second, attach the two M8 ring terminals to the battery: red to positive, black to negative. Third, plug the green terminal block into the appropriate BVS port on the charge controller or charger. Connection can be verified with a multimeter reading at the terminal block screws.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccurate terminal voltage:\u003c\/strong\u003e reads voltage directly at the battery bank, not at the controller's terminals\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e16.4 ft (5 m) cable:\u003c\/strong\u003e accommodates installations where the controller and battery bank are separated by a long wire run\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eM8 ring terminals:\u003c\/strong\u003e approx. 5\/16\" ring terminals for a secure battery connection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-voltage support:\u003c\/strong\u003e compatible with 12V, 24V, 36V, and 48V battery banks\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-chemistry support:\u003c\/strong\u003e works with lead-acid (Flooded, Sealed, Gel) and lithium iron phosphate batteries\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlug-and-play connector:\u003c\/strong\u003e green terminal block plugs directly into the compatible port on supported Renogy controllers and chargers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eValue\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNominal Voltage Compatibility\u003c\/td\u003e\n      \u003ctd\u003e12V \/ 24V \/ 36V \/ 48V battery banks\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCable Length\u003c\/td\u003e\n      \u003ctd\u003e16.4 ft (5 m)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eTerminal Type\u003c\/td\u003e\n      \u003ctd\u003eM8 (approx. 5\/16\") ring terminals\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003e0.44 lbs (0.2 kg)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCompatible Controllers\u003c\/td\u003e\n      \u003ctd\u003eRover 60A\/100A, Rover Boost 10A, Rover Elite 20A\/40A, Adventurer Li 30A, 30A\/50A DC-DC MPPT battery charger\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCompatible Battery Chemistries\u003c\/td\u003e\n      \u003ctd\u003eLead-acid (Flooded, Sealed, Gel), lithium iron phosphate\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePackage Contents\u003c\/td\u003e\n      \u003ctd\u003e1x Battery Voltage Sensor with battery ring terminals\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe Renogy Battery Voltage Sensor suits off-grid builders (overlanders, van converters, RV owners, and cabin installers) who are running one of the compatible Renogy MPPT or PWM charge controllers or DC-DC MPPT chargers and whose wire run between the controller and battery bank is long enough to introduce a meaningful voltage difference between the two points.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThe Battery Voltage Sensor is not compatible with Renogy charge controllers or chargers that do not have a dedicated BVS, Battery Sampling, BATT, or Batt Remote port.
