Renogy Battery Voltage Sensor With Battery Ring Terminals

The Renogy Battery Voltage Sensor With Battery Ring Terminals Gives Your Charge Controller the Voltage at the Battery

The Renogy Battery Voltage Sensor With Battery Ring Terminals (BVS) is a 16.4 ft (5 m) sensing cable. A green terminal block plugs into your charge controller or charger, and M8 ring terminals connect to your battery bank. It reports the voltage measured at the battery terminals.

It is made for systems with long wire runs. Renogy says the voltage at a charge controller's terminals can differ from the voltage at the battery, and this sensor gives the controller the more precise battery reading.

Renogy Battery Voltage Sensor With Battery Ring Terminals Features

More Accurate Charging Voltage

The sensor sends the battery's voltage to the controller, which lets it adjust the charging stage more precisely. Renogy says this improves overall battery performance and life.

Plug-In Controller End, Ring Terminals at the Battery

Plug the green terminal block into the sensor port, then connect the red M8 ring terminal to the positive battery post and the black one to the negative. The M8 terminals are about 5/16 in. Renogy shows how to wire the green block, with red to the left (positive) pin and black to the right (negative) pin.

Works With 12V to 48V Battery Banks

Renogy lists 12V, 24V, 36V and 48V battery banks, and lead-acid (flooded, sealed and gel) and lithium iron phosphate batteries. Renogy also says it works with its Lithium 12V/48V, AGM 12V and GEL 12V batteries.

Certified Parts

Renogy lists the sensor as UL, ETL, CE, RoHS and FCC compliant.

Real-World Applications

Long cable runs. Use it when your controller is far from the battery bank, so the controller reads the battery's own voltage.

RV, marine and cabin systems. Renogy lists RV, marine, camping, outdoor, cabin and truck uses.

Practical Comparison

Battery Voltage Sensor Versus Controller Terminal Reading

Without the sensor, the controller reads voltage at its own terminals. With it, the controller reads at the battery terminals, which can differ over long wire runs.

Buyer Guidance

Match the Port on Your Controller

Each Renogy controller has its own port name. Renogy lists the Rover 60A and 100A "Battery Sampling" port, Rover Boost 10A and Rover Elite 20A and 40A "BATT" port, Adventurer Li 30A "Batt Remote" port, and the 30A and 50A DC-DC MPPT chargers "BVS" port.

Check the Connection

Make sure the green connector is firmly in its port. Renogy suggests using a multimeter to read the battery terminals to verify the connection.

This May Be A Good Fit If

• You use one of the listed Renogy controllers or chargers
• Your controller sits far from the battery bank
• Your battery bank is 12V, 24V, 36V or 48V

Common Questions

How Long Is the Cable?

It is 16.4 ft (5 m).

Does It Work With the Adventurer Li 30A?

Yes. Renogy says it works with the Adventurer Li 30A PWM charge controller through the "Batt Remote" port.

Why Would I Need It?

On long wire runs, the voltage at the controller can differ from the battery voltage. This sensor gives the controller the battery's voltage so it can adjust charging more precisely.

What Warranty Does It Have?

Renogy lists a 1-year material and workmanship warranty for accessories.
