The FlexiBatt Pro Hardcase Battery Pack is a powerful, mobile energy storage system for civil applications where electric power must be provided reliably, safely, and independently from the grid. The system combines high energy density with mechanical robustness, making it ideal for mobile, temporary, and off-grid deployment scenarios. As a portable energy storage solution in hardcase design, the FlexiBatt Pro is specifically designed for demanding environments where conventional power supply solutions are unavailable or unsuitable.
Mobile Power Supply in Hardcase Format
The FlexiBatt Pro is housed in a shock-resistant, weatherproof hardcase and is optimized for mobile use. It can be easily transported, quickly set up, and flexibly deployed at changing locations. Typical usage situations include:
Due to its compact design, the battery storage is suitable for both indoor and outdoor areas.

The FlexiBatt Pro is designed as a full-fledged outdoor battery and specifically developed for use in real outdoor conditions. Unlike conventional battery systems, which require protected indoor environments, this solution is designed to withstand weather, dust, mechanical stresses, and frequent location changes. The robust NANUK hard case reliably protects all components and ensures safe operation even in demanding environments.
As a fully off-grid solution, the outdoor battery provides electrical energy independent of the power grid. It is suitable for both temporary and long-term applications at remote locations, on construction sites, at events, or in municipal scenarios. The operation is silent and emission-free, making the FlexiBatt Pro ideal for sensitive areas where noise or exhaust fumes are unacceptable.
With its fully integrated design, the outdoor battery is ready for immediate use and requires no additional installation or technical preparation. Thus, the FlexiBatt Pro combines high operational reliability, ease of use, and maximum mobility in a compact, durable solution for civilian applications.
The used NANUK hard case offers professional protection against:
This makes FlexiBatt Pro suitable for use outdoors, in changing weather conditions and at locations without infrastructure. The case is designed for frequent location changes and meets high standards of durability and safety.

Mobile complete solution for off-grid power supply in civilian applications. The FlexiBatt Pro is a fully integrated, ready-to-use battery storage solution for civil applications where reliable power supply independent of the grid is required.
The entire system is housed in a durable, outdoor-capable NANUK hard case and designed for long-term use in challenging environments. The FlexiBatt Pro is not a modular component and not an open energy module, but rather a closed, portable all-in-one solution that can operate without additional installations or peripherals.
FlexiBatt Pro is a mobile, off-grid capable power supply solution for civil operational scenarios where electric energy is reliably, quietly, and independently from fixed infrastructure needed. Due to its fully integrated design in a robust NANUK hard case, the system is particularly suitable for applications with changing locations, limited space, and high operational safety requirements.
In remote work and operational areas such as construction sites, temporary measurement points, or mobile project locations, FlexiBatt Pro provides a stable energy source for several days. Typical consumers include lighting, sensors, measurement and monitoring technology, communication devices, and charging infrastructure for tools, tablets, or mobile devices. The noiseless operation and emission-free usage enable use even where classic generators are unsuitable or prohibited.
At temporary control, service, or information points, such as in the public sector, at events, or in infrastructural transition situations, FlexiBatt Pro ensures a reliable power supply without a permanent grid connection. Lighting, cameras, IT systems, routers, and mobile devices can be continuously operated without noise, exhaust fumes, or additional maintenance effort. This increases operational duration, improves working conditions, and reduces logistical dependencies.
FlexiBatt Pro also plays a central role in mobile technology and drone applications in a civil context. Research teams, surveying companies, or operators of inspection drones utilize the system as a power source for charging processes, ground stations, data evaluation, and communication. The stable output voltage protects sensitive electronics and allows for the parallel operation of multiple devices at one location.
In research, environmental, and measurement projects, FlexiBatt Pro supports the autonomous operation of sensors, data collectors, and analysis devices. Especially during long-term measurements or in natural areas, a quiet, emission-free power supply is crucial to avoid disturbing the environment and surroundings. The compact, closed design facilitates transport and enables quick location changes.
For mobile work, rest, and standby areas, FlexiBatt Pro provides a secure energy foundation. Lighting, charging points for personal equipment, small ventilation or air conditioning components, and communication tools can be reliably operated without burdening the surroundings with noise or exhaust fumes. This is particularly relevant during extended deployments, night work, or in sensitive areas.
Also, mobile supply and medical units in the civil context benefit from FlexiBatt Pro as a reliable power source. Medical small devices, lighting, documentation systems, and communication can be operated independently from the grid. The uninterrupted power supply increases safety for both users and assisted individuals.
Moreover, FlexiBatt Pro is used for temporary securing of civil infrastructure, such as during power outages, maintenance work, or transitional solutions. Small administrative offices, communication nodes, mobile offices, or emergency shelters can be supplied with electricity quickly and flexibly, without resorting to loud or emission-intensive solutions.
Device Swap (Fast and Highly Mobile)
FlexiBATT Pro is designed for quick deployment: When the power is depleted, you can simply swap the entire device for a fully charged one. The depleted device is then recharged in a protected area.
Battery Change (only the small battery module)
Alternatively, you can just replace the smaller battery. The exchange is quick and straightforward. This way, you can carry more capacity in a smaller volume for flexible recharging or replacements.
Not Hot-Swappable (Short Interruption)
Important: The battery is not hot-swappable. This means: During the battery change, there will be a brief interruption in the power supply of the FlexiBATT Pro.

FlexiBatt PRO 230V
FlexiBatt Pro is a robust and modular 48V battery system designed for professional users and demanding off-grid applications. With a 2.5 kWh capacity, integrated 230V output, and up to 2500W continuous power, it delivers reliable energy for tools, equipment, mobile installations, and critical applications.
Thanks to high-quality EU cells, a compact design, and versatile connections, FlexiBatt Pro is ideal for construction sites, emergency operations, field use, and off-grid power supply. USB and USB-C outputs also allow for charging mobile devices, while the Neutrik connector supports the operation of a Euroheater air heater for up to four days.
FlexiBatt PRO MIL 24 & 230V
FlexiBatt Pro MIL is a rugged and modular 48V battery system for professional field and special operations. With a 2.5 kWh capacity, integrated 230V output, and up to 2500W continuous power, it delivers reliable energy for equipment, tools, and critical applications.
Compared to the FlexiBatt Pro, the MIL version additionally features a dedicated 24V DC output with up to 480W via an Amphenol connector. This makes it particularly suitable for military systems, mission-critical equipment, and applications requiring a stable 24V power supply.
FlexiBatt PRO MIL-SPEC 24 & 48V
FlexiBatt Pro MIL-SPEC is the specialized 48V battery solution for demanding DC applications in military and industrial systems. With a capacity of 2.5 kWh, it delivers direct high-current outputs of 48V up to 2200W and 24V up to 480W.
Unlike the PRO variants, which focus on 230V AC power supply, FlexiBatt Pro MIL-SPEC is designed for direct DC power supply. This makes it particularly suitable for tactical platforms, mission-critical equipment, and systems that are efficiently operated directly at 24V or 48V.
