Akumulators 25,6V/200Ah NG

The Victron Energy Lithium NG battery has a nominal voltage of 25.6 V and a nominal capacity of 200 Ah. This represents a nominal energy of 5120 Wh at 25 °C.

A Victron Energy NG-type Battery Management System (BMS) is mandatory for this battery. It must be a Lynx Smart BMS NG 500 A/1000 A or a later model. The BMS is sold separately.

The cycle life of the Victron Energy Lithium NG battery depends on the depth of discharge (DoD):

At 80 % DoD: approximately 2500 cyclesAt 70 % DoD: approximately 3000 cyclesAt 50 % DoD: approximately 5000 cyclesThese figures assume a capacity maintained at ≥ 80 % of the nominal capacity.

Yes, although the battery has a nominal voltage of 25.6 V, it can be connected in series, parallel or a combination of both to create battery banks suitable for 12 V, 24 V or 48 V systems.

The battery can be mounted using straps or mounting brackets. Mounting brackets are included with the battery, making installation easier and ensuring optimal securing against sliding and tipping.

The self-discharge rate of the Victron Energy Lithium NG battery is very low, at a maximum of ≤ 3 % per month at 25 °C.

A single system can accommodate up to 50 batteries when configured at 12 V or 24 V. For 48 V systems, a maximum of 25 batteries can be used. This allows for a maximum energy storage capacity of 384 kWh for 24 V systems and 128 kWh for 48 V systems.

The battery dimensions are 235 mm (height) x 648 mm (width) x 162 mm (depth). The estimated weight of the battery is 37 kg.

Yes, NG Lithium batteries feature enhanced intrusion protection (IP65 rating). They are effectively sealed against dust and can withstand low-pressure water jets, making them suitable for environments where exposure to dust and water is a concern.

The battery is equipped with an integrated shunt that transmits in real time essential data such as voltage, current, and battery temperature to the BMS. This data is used by the BMS to calculate the state of charge and generate specific warnings or alarms.

The battery can be discharged within a temperature range of -20 °C to +50 °C. For charging, the recommended temperature range is +5 °C to +50 °C. It is important to respect these ranges for battery performance and longevity.

The Victron Energy Lithium NG 25.6V/200Ah battery can support a maximum continuous discharge current of 200 A (1C). For short peaks, it can provide a maximum pulse discharge current of 400 A for 10 seconds (2C).

Monitoring and control are performed via the VictronConnect app (each BMS model is Bluetooth-enabled), a GX communication center, or the VRM portal. You can view real-time parameters such as cell status, cell voltages, battery current, and temperatures.

Yes, Victron Energy Lithium NG batteries include cell balancing and monitoring. The cell balancing/monitoring cables can be connected in series ("daisy-chained") and must be connected to the battery management system (BMS).

Yes, the battery can be placed on its side.

The BMS provides multi-layer protection:

It generates a pre-alarm if a cell voltage drops below 3.0 V. It disconnects the load if a cell voltage drops below 2.8 V. It stops the charging process if a cell voltage exceeds 3.6 V, or if the temperature becomes too high or too low.

The battery is connected electrically via M8 terminals, using threaded inserts and bolts.

Yes, it is crucial to wear safety glasses and protective clothing. Use insulated tools and avoid wearing metallic objects. Handle the battery with care as it is sensitive to mechanical shocks and is heavy (37 kg), requiring appropriate lifting aids. Never open or dismantle the battery.

The battery firmware is automatically updated by the BMS (Battery Management System), simplifying maintenance and ensuring the battery always operates with the latest software version.

Yes, the Victron Energy Lithium NG 25.6V/200Ah battery absolutely requires an external Battery Management System (BMS) approved by Victron Energy to operate correctly and safely. The BMS is a mandatory component and must be purchased separately.

The BMS performs several critical functions:

Automatic management: It automatically detects system voltage and battery bank configuration (series, parallel, or series/parallel).Monitoring and protection: It monitors battery voltage, current, and temperature in real time. It triggers pre-alarms if a cell voltage drops below 3.0 V and disconnects the load if it falls below 2.8 V. It also stops the charging process if a cell voltage exceeds 3.6 V or if the temperature is too high or too low.Cell balancing: Although the battery has built-in cell balancing and monitoring, communication cables must be connected to the BMS for this function to be managed.Firmware updates: The battery firmware is automatically updated by the BMS.Data access: Battery data (state of charge, cell voltage, current, temperature) are transmitted to the BMS and can be viewed via the VictronConnect app, a GX device, or the VRM portal.Compatible and mandatory BMS models include the Lynx Smart BMS NG 500 A/1000 A (or later models).
