Victron Battery Monitor BMV-702 Black (Non-Bluetooth)

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.

Take Control of Your Energy System

Equip your battery bank with the Victron BMV-702 Battery Monitor and gain the insights needed to maximise performance and longevity. Order today to ensure your power system operates at peak efficiency.

WARRANTY

Victron Energy Limited Warranty Policy

Direct Customers

Victron Energy provides the following warranty to any direct customer (OEM, distributor or dealer) in relation to any products that Victron Energy has directly sold to the direct customer. This warranty is not an end-user warranty between Victron Energy and an end-user, and end-users shall not have any rights or remedies under this limited warranty towards Victron Energy directly. The direct customer shall, in turn, ensure that the end-user is provided with a warranty identical to this warranty, subject to applicable local mandatory law.

End-Users

Victron Energy may also provide a warranty directly to end-users, in which case the below warranty conditions equally apply to such warranty. In that case, end-users shall claim their warranty at their place of purchase or through the original direct customer of Victron, which can be found through the support section on Victron’s website https://www.victronenergy.com/support. Hence, the direct customer shall on behalf of Victron Energy deal with any warranty claims made under any warranty that Victron Energy may provide directly to end-users. This support section on Victron’s website https://www.victronenergy.com/support will provide further guidance on the procedure for end-users to make a claim under this limited warranty.

If the end-user is a consumer – a natural person who is acting for purposes which are outside that person's trade, business, craft or profession – the following applies. The rights and remedies granted to the consumer under this limited warranty are without prejudice to the consumer’s statutory rights. Furthermore, the consumer is entitled by law to remedies from the seller free of charge in the event of a lack of conformity of the goods (such as repair, replacement, price reduction or rescission), which remedies are not affected by this limited warranty.

Warranty

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 original 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 original end-user, with a maximum of 30 months from the Victron Energy invoice date, Lithium batteries: 3 years from date of purchase by the original end-user, with a maximum of 42 months from the Victron Energy invoice date. In addition to this, proof of correct battery usage is required when making a battery warranty claim.

For a 10% surcharge on the current net price for products that came with a 5-year warranty, an additional 5 years of warranty can be purchased by Victron’s direct customers, bringing the total warranty to 10 years. Warranty extensions need to be applied for ultimately one year before the expiration of the original term. Victron may ask proof that the product was still functional at the time of purchase of the extended warranty.

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

Victron Energy shall not be liable for damages, whether direct, incidental, special, or consequential, even caused by negligence or fault.

As a product requires service, it must be brought back to the place of purchase. In case no contact can be made with the merchant, or if he is either unable or not allowed to provide service, direct contact should be made with Victron Energy through the support section on Victron’s website.

In case Victron Energy replaces a product, it will own the replaced product. Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers when performing warranty repairs or building replacement products.

If Victron Energy repairs or replaces a part of a product, its warranty term is not extended: the warranty will apply for the remaining term of the original warranty term. For example, if Victron Energy replaces a product with a 5-year warranty after 3 years, the warranty of this product will apply for another 2 years, with a minimum of 6 months.

All remedies and the measure for damages are limited to the above. Victron Energy shall in no event be liable for consequential, incidental, contingent or special damages, even if having been advised of the probability of such damages.

The foregoing limited warranty provided by Victron Energy is in lieu of any other warranties, express or implied arising by law, course of dealing, course of performance, usage of trade or otherwise, of any kind whatsoever including, without limitation, warranties of merchantability or fitness for a particular purpose, with respect to any product. The above is without prejudice to the arrangement for consumers detailed above.
