Victron VE.Bus BMS NG

DESCRIPTION

Victron VE.Bus BMS NG: Precision Battery Management for Lithium NG Systems

Engineered for Victron Lithium NG Batteries

The Victron VE.Bus BMS NG is a dedicated Battery Management System designed exclusively for Victron Lithium NG batteries. It communicates directly with Victron inverters and inverter/chargers via the VE.Bus protocol, ensuring coordinated protection and optimal performance. This unit is not compatible with Victron Lithium Battery Smart batteries.

Intelligent Monitoring and Control

This advanced BMS continuously monitors individual cell voltages and temperatures, safeguarding against over-voltage, under-voltage, and thermal extremes. Integrated Bluetooth Smart connectivity provides direct access to all Lithium NG batteries, enabling real-time monitoring of State of Charge (SoC) and current via the VictronConnect app. This eliminates the need for additional components like a SmartShunt, simplifying installation and reducing system complexity.

Scalable Architecture for Demanding Applications

The VE.Bus BMS NG supports large-scale energy storage configurations, making it suitable for a wide range of installations:

  • Up to 50 batteries in 12V or 24V banks (maximum 192 kWh and 384 kWh respectively)
  • Up to 25 batteries in 48V banks (maximum 128 kWh)

This scalability is ideal for caravan, RV, marine, off-grid, industrial, and tiny home energy systems. For even larger setups, multiple Lynx Smart BMS units can be paralleled for increased capacity and redundancy.

Comprehensive Protection Outputs

The BMS features multiple control outputs to manage system safety:

  • Load Disconnect Output: Prevents deep discharge by controlling inverters, BatteryProtect units, and other loads.
  • Charge Disconnect Output: Stops charging equipment to avoid over-voltage conditions.
  • Pre-Alarm Output: Provides early warning of low voltage before load disconnection occurs.
  • Remote On/Off: Allows external switching of both load and charge disconnects for flexible system control.
  • LED Indicators: Display Bluetooth status and system warnings at a glance.

Built for Reliability in Harsh Environments

Housed in a compact, matte black ABS enclosure (23.2 mm x 95.0 mm x 105.8 mm), the VE.Bus BMS NG is rated IP20 and operates reliably in temperatures from -20°C to +50°C. Its low power consumption—just 10 mA during regular operation—minimises energy drain on the battery bank. The dual RJ45 VE.Bus ports enable seamless integration with Victron MultiPlus and Quattro inverter/chargers, while the 6-way terminal block simplifies wiring for battery, GX-power, and alarm outputs.

Streamlined Installation and Firmware Updates

With plug-and-play configuration and firmware update capability via the VictronConnect app, the VE.Bus BMS NG reduces setup time and ensures your system stays current with the latest features. Its direct battery communication eliminates the need for additional shunts or sensors, lowering overall system cost and complexity.

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. 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 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.

This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use like:

  • Reversed battery polarity.
  • Inadequate connection.
  • Mechanical shock or deformation.
  • Contact with liquid or oxidation by condensation.
  • Use in an inappropriate environment (dust, corrosive vapour, humidity, high temperature, biological infestation, etc.).
  • Breakage or damage due to lightning.
  • Connection terminals and screws destroyed or other damages, like overheating, due to insufficient tightening.
  • For any electronic breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state of the internal control diode and/or the input/output X and Y capacitors determine the warranty.

This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone other than Victron Energy or one of its authorized Repair Centres. In order to qualify for the warranty, the product must not be disassembled or modified.

This warranty and our warranty obligations thereunder (repair, replacement or credit) are the direct customer’s and, if applicable, the end-user’s sole rights and remedies and our sole obligations with respect to any defective and/or non-conforming product or breach of warranty and is subject to and without prejudice to the limitations of liability in this warranty.

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.

Life Support Policy

As a general policy, Victron Energy does not recommend the use of any of its products in life support applications where failure or malfunction of Victron Energy's product can be reasonably expected to cause the failure of the life support device or to significantly affect its safety or effectiveness. Victron Energy does not recommend the use of any of its products in direct patient care. Victron Energy will not knowingly sell its products for use in such applications unless it receives in writing assurances satisfactory to Victron Energy that the risks of injury or damage have been minimized, the customer assumes all such risks, and the liability of Victron Energy is adequately protected under the circumstances.

Warranty on repairs for products outside their warranty period

The warranty period on products that are outside their warranty period and have been repaired by Victron Energy or one of the Victron Energy Repair centres is six (6) months from delivery. The same applies to spare parts and circuit boards that have been supplied or repaired by Victron Energy.

Transport

It is the responsibility of the sender to sufficiently package these products. The transport must be organized in a way to avoid any damage, especially when a single unit or heavy unit is sent.

Severability

If a part of the terms and conditions of this warranty is held invalid, void or unenforceable due to any particular national or international legislation, it shall not affect other parts of the terms and conditions of this warranty.

Applicable law

This warranty is exclusively governed by the laws of the Netherlands, to the exclusion of the UN Convention on Contracts for the International Sale of Goods.
