Accurate battery voltage readings so your charger charges smarter and your battery lasts longer

Battery Voltage Sensor (BVS)

Overview

The Battery Voltage Sensor (BVS) delivers the actual voltage at your battery bank to the charge controller so charging stages are adjusted precisely. It’s a plug-and-play accessory that reduces the effects of voltage drop on long cable runs, helping your battery charge more accurately and last longer.

Benefits

• Extend battery life by letting the controller use the true battery voltage for charging decisions.
• Improve charging accuracy so batteries are less likely to be overcharged or undercharged.
• Reduce guesswork and manual monitoring — a single connection gives your controller better information.
• Works with existing Renogy controllers and chargers to improve overall system performance without major changes.
• Quick installation means less downtime and fewer installation mistakes on the first setup.

Features

• Provides precise battery terminal voltage to the charge controller for more accurate charge-stage control.
• Plug-and-play connector for compatible Renogy ports (Battery Sampling, BATT, Batt Remote, BVS).
• Compatible with 12V, 24V, 36V and 48V battery banks.
• Works with lead-acid (flooded, sealed, gel) and lithium iron phosphate (LiFePO4) batteries.
• Includes two M8 ring terminals (red = positive, black = negative) for direct battery connection.
• 5 m (16.4 ft) cable gives flexibility for controller placement and long cable runs.
• Certified to common safety and compliance standards (UL, ETL, CE, RoHS, FCC).
• Simple 3-step installation: assemble the green terminal, attach ring terminals to the battery, plug into controller/charger port.
