Renogy Battery Voltage Sensor with Battery Ring Terminals

The Battery Voltage Sensor (BVS) is the perfect solution by providing a more accurate battery voltage to the controller and allowing it to adjust the charging stage more precisely resulting in overall extension of your battery life. In certain applications with long line runs, there can be a difference between the voltage measured at an MPPT/PWM solar charger’s terminals and that measured at the battery terminals. This BVS provides a more precise voltage from the battery terminals. It's a plug-and-play solution for your solar system.
