DESCRIPTION

Victron BMV-702: Precision Battery Monitoring for 12V to 48V Systems

Advanced Battery Management with Midpoint Voltage Detection

The Victron BMV-702 Battery Monitor functions as an intelligent fuel gauge for your battery bank, delivering real-time data on voltage, current, state of charge, and time remaining. Unlike basic voltage meters, the BMV-702 employs sophisticated algorithms that account for discharge rate, temperature, and battery age, ensuring accurate readings even under dynamic loads. This model includes a dedicated secondary input for midpoint voltage monitoring, a critical feature for identifying cell imbalances in series-connected battery strings before they lead to costly failures.

Designed for lithium and lead-acid batteries, the BMV-702 supports systems from 6.5V to 95V DC, making it suitable for 12V, 24V, and 48V installations in caravans, marine vessels, and off-grid solar setups. The included 500A/50mV shunt provides high-resolution current measurement down to 10mA, while the VE.Direct communication port enables integration with Victron GX devices and the VictronConnect app for detailed historical analysis.

Midpoint Voltage Monitoring: Protect Your Battery Investment

In series-connected battery banks, a single failing cell can compromise the entire string. The BMV-702 continuously measures the voltage at the midpoint of the bank, detecting deviations that indicate imbalance, aging, or damage. Early warning via programmable alarms allows corrective action, such as equalisation charging or cell replacement, preventing irreversible damage to expensive battery sets. This feature is especially valuable for large lithium or AGM banks where replacement costs are significant.

Key Features

  • Midpoint voltage monitoring detects cell imbalance in series battery banks
  • High-precision 500A shunt with 10mA resolution for accurate current tracking
  • Programmable relay for load shedding or generator start
  • VE.Direct port for connection to GX devices and VictronConnect
  • Wide 6.5–95V DC input range compatible with 12V, 24V, and 48V systems
  • Low self-consumption of 4mA at 12V minimises battery drain
  • Historical data logging for performance analysis and troubleshooting

Easy Installation and Flexible Mounting

The BMV-702 ships with a 500A/50mV shunt featuring M10 (approx. 3/8") brass terminals, a 10-metre RJ12 cable, and a fused battery connection. The round head unit (63mm diameter) can be flush-mounted using the included square bezel (69x69mm) for a clean dashboard appearance. All electrical connections terminate at the shunt’s quick-connect PCB, simplifying wiring and reducing installation time.

Applications

Ideal for monitoring lithium battery banks in caravans, RVs, and boats, the BMV-702 also excels in off-grid solar systems, backup power installations, and industrial battery rooms. Its ability to track multiple parameters helps users optimise charging, extend battery life, and avoid unexpected downtime.

WARRANTY

Victron Energy Limited Warranty Policy

Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the end user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead acid batteries; 2 years from date of purchase by the end user, with a maximum of 30 months from the Victron Energy invoice date, Lithium-ion batteries; 3 years from date of purchase by the end user. In addition to this proof of correct battery usage is required when making a battery warranty claim.

During this period, Victron Energy will, at its option, repair or replace the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation and re‐installation.
