Mobile ventilation systems for tactical and military use
Flexibatt MAXI is a modular UPS and energy storage system that has been specially developed for military, government, and security-critical applications. It is designed to provide a reliable, quiet, and uninterrupted power supply in remote, low-energy, and highly dynamic areas of operation.
Unlike traditional diesel generators or civilian battery storage systems, the Flexibatt MAXI takes a consistently tactical approach to system design, focusing on scalability, redundancy, low signature, and rapid deployability.

True modularity instead of monoblock systems
While many energy storage systems are designed as closed units, the Flexibatt MAXI allows capacity to be expanded or reduced as needed. This reduces weight, volume, and logistics costs and enables precise adaptation to the respective order.
Full UPS capability
The Flexibatt MAXI is not just an energy storage device, but a true UPS. Critical consumers remain stably supplied even during generator changes, load peaks, or voltage drops. This is particularly important for command, communication, and medical systems.
Multi-voltage capability
The simultaneous provision of 400 V, 230 V, and 12 V sets the system apart from many other solutions. This allows heavy infrastructure, standard equipment, and tactical electronics to be operated in parallel without additional converters or adapters.
Signature reduction
In battery mode, the Flexibatt MAXI operates:
This represents a decisive tactical advantage over diesel generators, especially in reconnaissance or threatened areas of operation.
Key advantages in military use
The UPS function (uninterruptible power supply) in mobile battery storage systems ensures that connected devices continue to be supplied with power automatically and without interruption in the event of a power failure or voltage fluctuations. This keeps important consumers running smoothly and protects them from failure.

The Flexibatt MAXI consists of a central master unit and several modular 5 kWh UPS battery modules. Depending on the application requirements, the system can be flexibly scaled from 5 kWh to 50 kWh.
The modules are integrated without structural changes. This allows the same system base to supply both small tactical elements and energy-intensive facilities such as command posts, field hospitals, or logistics hubs.
Key technical features:
FlexiBatt MAXI is a high-performance UPS and energy storage system. It combines a main unit with modular 5 kWh UPS units that can be expanded to up to 50 kWh as needed. The system is lightweight, portable, and designed for rapid deployment. It provides reliable, uninterrupted power for field hospitals, command posts, and other energy-intensive applications—even in extreme or remote conditions.

Combat and command posts
In combat posts, command posts, and tactical operations centers, an absolutely stable power supply is crucial for command capability, situational awareness, and decision-making processes. The Flexibatt MAXI provides an uninterruptible power source that ensures continuous operation even when the primary power supply is unstable or fluctuating.
Among other things, it supplies:
Thanks to the integrated UPS function, all systems remain active without interruption even during generator changes, load peaks, or short-term failures.
At the same time, silent battery operation significantly reduces the acoustic and thermal signature, which is a considerable tactical advantage, especially in forward or camouflaged command posts.
Field hospitals and MedEvac areas
In field hospitals, casualty collection points, and MedEvac zones, a reliable, clean, and quiet power supply is vital. Medical devices are sensitive to voltage fluctuations and failures, which is why the UPS capability of the Flexibatt MAXI plays a central role here.
Typical applications include:
Emissions-free battery operation allows use even in the immediate vicinity of wounded personnel, without noise, exhaust fumes, or vibrations. In combination with generators, the Flexibatt MAXI can absorb peak loads and significantly reduce generator running times, saving fuel and minimizing logistical burdens.
Sensor, radio, and reconnaissance nodes
Modern military operations are heavily dependent on sensor technology, radio communications, and reconnaissance systems. These systems require a continuous, stable power supply with the lowest possible signature.
The Flexibatt MAXI is particularly suitable for:
When running on battery power alone, the system operates completely silently and without emissions, which makes covert deployment much easier. At the same time, its high reliability ensures that there is no data loss or system failure, even with unstable power supply or changing energy sources. This is particularly relevant for permanently operated, unattended, or forward nodes.
Logistics and maintenance facilities
Logistics hubs, workshop areas, and maintenance facilities often experience fluctuating loads and high short-term power requirements. The Flexibatt MAXI can be used here both as a primary energy source and as a powerful buffer.
Typical areas of application:
By absorbing peak loads, generators can be smaller, which reduces weight, consumption, and maintenance costs. At the same time, operation remains stable and predictable even in the event of short-term malfunctions.
Hybrid energy islands
A particularly effective use of the Flexibatt MAXI is its integration into hybrid energy islands consisting of:
In this network, the Flexibatt MAXI performs several central functions:
The result is a significantly longer service life, reduced fuel consumption, and a lower acoustic signature. This represents a decisive operational advantage, especially in longer-lasting operations or in situations where supplies are limited.
