The Victron BMV battery monitor range provides high-precision battery monitoring for caravan, RV, marine and off-grid power systems. The range calculates amp-hours consumed and battery state of charge by measuring the current flowing in and out of the battery.
Choose the BMV-700 for single-battery monitoring, the BMV-702 for dual-battery or auxiliary input monitoring, the BMV-712 Smart for built-in Bluetooth monitoring through VictronConnect, or the high-voltage BMV models for compatible higher-voltage battery systems.
