Mobile ventilation systems for tactical and military use
FlexiBatt PRO is a modular 48 V battery system designed for professional use and off-grid applications. With an output of 2.5 kWh, it provides reliable power for a wide range of tools, devices, and electronic equipment. The system is designed for demanding environments and features a robust housing, 12 V and USB outputs, and an integrated charger with solar input for flexible power supply. The battery modules can be quickly replaced, ensuring uninterrupted operation even when the charge level is low.
The Flexibatt PRO is a compact, highly mobile energy system that has been specially developed for decentralized and signature-critical military applications. It delivers reliable electrical power wherever generators are too loud, too conspicuous, or logistically impractical.
What makes the Flexibatt PRO special is its combination of mobility, robust construction, and professional power quality. It provides clean, stable voltage for sensitive electronics and also functions as an uninterruptible power supply to prevent failures and interruptions.
Thanks to its modular design, multiple voltage outputs, and the option to integrate solar panels, the Flexibatt PRO is ideal for mobile command and communications equipment, sensor technology, drone teams, medical units, and covert operations.
Quiet, emission-free operation, high operational reliability, and easy deployability make the Flexibatt PRO a tactical enabler for modern, networked operations where energy availability directly determines operational capability.

SolarPanel
Lightweight, foldable solar panel for charging the FlexiBatt PRO. It delivers up to 300 W of charging power and is ideal for off-grid use. Made from robust, weather-resistant materials for reliable operation in demanding conditions.
Device replacement (fast and highly mobile)
FlexiBATT Pro is designed for rapid deployment: when the power runs out, you can simply replace the entire device with a fully charged one. The discharged device is then recharged in a protected area.
Battery replacement (only the small battery module)
Alternatively, you can replace only the smaller battery. Replacement is quick and easy. This allows you to carry more capacity in less volume and recharge or replace flexibly.
Not hot-swappable (short interruption)
Important: The battery is not hot-swappable. This means that when the battery is replaced, there will be a short interruption in the power supply to the FlexiBATT Pro.
Remote observation posts and OPs
Observation posts (OPs) often operate covertly for several days or weeks without fixed infrastructure. The Flexibatt PRO is suitable as the primary power source here, as it ensures a stable supply with minimal acoustic and thermal signature.
Typical consumers:
Its silent operation prevents acoustic reconnaissance, while its compact design allows for inconspicuous integration into camouflaged positions.
Checkpoints, barriers, and control points
Temporary or semi-permanent checkpoints and control points require reliable power without having to run generators continuously. The Flexibatt PRO offers a robust, emission-free solution here.
Areas of application:
The use of the battery reduces noise pollution and extends the operating time, especially during nighttime operations.
Tactical drone and UAS teams
UAS and drone teams are highly dependent on energy, but often work on the move and without a fixed power supply. The Flexibatt PRO serves as the central power source for launch, charging, and evaluation processes.
Typical applications:
The stable output voltage protects sensitive electronics and enables parallel charging of multiple systems.
Small-scale electronic warfare
A reliable power supply is essential for electronic protection or jamming measures at squad or platoon level. The Flexibatt PRO supports the operation of:
Emission-free operation is particularly relevant here, as generators would represent an unacceptable signature in such deployment scenarios.
Covert rest and standby areas
In covert rest and standby areas, the Flexibatt PRO improves both the operational capability and safety of the forces deployed.
It supplies:
This allows soldiers to rest without revealing their position through noise or exhaust fumes.
Mobile medical teams and advanced first aid
Small, mobile medical units benefit from the Flexibatt PRO as a reliable power source, especially during rapid deployments or operations away from fixed infrastructure.
Applications:
The uninterrupted supply reduces risks for wounded personnel and medical staff.
Securing civilian infrastructure in military operations
In stabilization and support operations, the Flexibatt PRO is also used to temporarily secure critical civilian infrastructure.
Examples:
Quiet, emission-free operation is particularly important here for acceptance and safety.
Summary classification
The Flexibatt PRO is a highly flexible energy system for decentralized, mobile, and signature-critical operations. It is particularly suitable for:
It thus ideally complements larger systems such as the Flexibatt MAXI and closes the gap between individual battery power supplies and stationary energy systems.
