Victron BMV-702 — Dual Battery Monitoring

For users who need an accurate overview of the health of their batteries, the Victron BMV-702 offers a reliable solution. This battery monitor displays voltage, current, state of charge (SoC) and even estimated time to discharge, which is key to effective real-time energy management. With a second input, it is possible to monitor the voltage of a second battery, measure temperature (with an optional sensor) or monitor the center voltage of the battery bank, which is essential for protecting expensive systems. The combination of precise measurements and intelligent features makes it the ideal choice for demanding applications, including industrial uses.

Accurate battery health measurement and analysis

The Victron BMV-702 is designed to provide detailed information on every aspect of battery operation. With a high measurement resolution of ±0.01 A and ±0.01 V and an accuracy of ±0.4% for current and ±0.3% for voltage, you get reliable data that allows you to optimize system performance. The monitor software takes into account factors such as battery age, discharge current and temperature, ensuring the most accurate calculations of remaining capacity.

Center Voltage Monitoring and Battery Bank Protection

The center voltage of a battery bank is an indicator of the balance between individual cells. Deviations from the ideal value can signal problems such as differences in capacity, temperature or internal leakage currents. The BMV-702 can detect these deviations in time, allowing you to perform the necessary service before the entire battery bank is damaged. This feature is particularly important for maximizing the service life and operational reliability of the system.

Convenient installation, connection and integration

The BMV-702 monitor is easy to install thanks to its flush-mounted design with a 63 mm diameter cutout and IP55 protection, which protects it from dust and splashing water (not intended for outdoor use). Electrical connection is made via a quick-connect PCB and the monitor is connected to the shunt using a standard RJ-12 cable, which is included in the package. Thanks to the VE.Direct port, the device can be easily integrated with other Victron Energy products such as the Color Control GX, and with the optional Bluetooth adapter, you get the option of management via smartphone.
