Victron Battery Monitor BMV-702
Precision Monitoring for Single & Dual Battery Banks | Model: BAM010702000
The Victron Battery Monitor BMV-702 is a high-precision battery monitoring system designed to provide accurate, real-time insights into your battery bank's status. This essential device tracks critical parameters such as voltage, current, power, consumed ampere-hours, and state of charge, acting as a reliable "fuel gauge" for your battery system.
Ideal for a wide range of applications from off-grid solar setups to marine and RV systems, the BMV-702 helps users understand their energy consumption and battery health. Its advanced algorithms account for discharge current, temperature, and battery age to provide a precise "time to go" reading, ensuring you always know your remaining capacity.
DUAL INPUT CAPABILITY: The BMV-702 features an additional input for monitoring a second battery's voltage, temperature (with optional sensor), or midpoint voltage.
Key Features
| ▶ Comprehensive Monitoring — Displays voltage, current, power, consumed Ah, and state of charge. |
| ▶ Time-to-Go Indication — Provides an accurate estimate of remaining battery life at current discharge rates. |
| ▶ Programmable Alarms & Relay — Set visual/audible alarms and configure the relay to manage loads or start a generator. |
| ▶ Dual Battery/Midpoint Monitoring — Auxiliary input for a second battery voltage, temperature (optional sensor), or midpoint voltage. |
| ▶ High Resolution & Low Consumption — Measures current with 10 mA (0.01A) resolution and features very low power draw. |
| ▶ Historical Data Storage — Records a wide range of events to evaluate usage patterns and battery health over time. |
| ▶ Easy Installation — Quick-connect PCB on the shunt and standard RJ12 cable for simple setup. |
| ▶ Flexible Display Options — Includes separate front bezels for square or round display appearance. |
| ▶ VE.Direct Communication — Enables connection to other Victron devices and optional Bluetooth Smart dongle for app monitoring. |
| ▶ 5-Year Warranty — Backed by Victron Energy's standard manufacturer warranty for peace of mind. |

Built-In Protection Functions
The Victron BMV-702 incorporates several features to help protect your battery system and provide timely warnings. These include programmable visual and audible alarms for various parameters such as low state of charge, low voltage, and high voltage. • A programmable relay can be configured to automatically disconnect non-critical loads or activate a generator when specific battery conditions are met, preventing excessive discharge or ensuring power continuity. • Midpoint voltage monitoring (unique to the BMV-702) provides an early warning of potential issues in series-connected battery banks, indicating an imbalance that could lead to premature battery failure.
Common Questions
What is the main difference between the BMV-700 and BMV-702?
The primary difference is that the BMV-702 includes an additional input. This auxiliary input can be used to monitor the voltage of a second battery (e.g., a starter battery), measure battery temperature (with an optional sensor), or monitor the midpoint voltage of a battery bank. The BMV-700 does not have this auxiliary input.
Can I monitor the BMV-702 from my smartphone?
Yes, you can monitor the BMV-702 from your smartphone or other Bluetooth-enabled device by adding an optional Victron VE.Direct Bluetooth Smart dongle. This dongle allows you to connect wirelessly to the VictronConnect app for real-time data and settings adjustments.
What is midpoint voltage monitoring and why is it important?
Midpoint voltage monitoring is a feature that measures the voltage at the midpoint of a series-connected battery bank. A significant deviation from the ideal midpoint voltage can indicate an imbalance or a failing cell within the bank, providing an early warning sign to prevent further damage and extend battery life.
Is the BMV-702 suitable for lithium batteries?
Yes, the BMV-702 is compatible with various battery types, including lead-acid and lithium (LiFePO4) batteries. Its precise monitoring capabilities are particularly beneficial for lithium batteries, which require accurate state of charge tracking to prevent over-discharge.
Installation Notes
- The BMV-702 is designed for flush mounting. It comes with both square and round bezels to suit your panel aesthetics.
- All electrical connections are made to the quick-connect PCB on the current shunt, which then connects to the monitor via a standard RJ12 telephone cable.
- Ensure proper wiring according to the manufacturer's instructions to avoid damage and ensure accurate readings.
- The unit has an IP55 rating, meaning it is protected against dust and low-pressure water jets, but it is not intended for outdoor exposure to heavy weather.
Before You Buy
- Verify the voltage range (6.5-95 VDC) is compatible with your battery system.
- Consider if you require the optional VE.Direct Bluetooth Smart dongle for smartphone monitoring.
- If monitoring battery temperature, an optional temperature sensor (ASS000100000) is required.
- Ensure you have adequate space for flush mounting the display unit (body diameter 52mm, depth 31mm).
Please verify all specifications and compatibility requirements with your existing system before purchase. Manufacturer's warranty applies.
