FOR RESILIENT APPLICATIONS AND CRITICAL INFRASTRUCTURES

FlexiBatt is a groundbreaking battery system developed in Norway. It is designed for demanding conditions. With an impressive capacity of 2.3 kWh in a lightweight design, it is ideal for operating the Euroheater 4D for up to 3–4 days on the lowest setting. Manufactured in Norway from high-quality components, FlexiBatt is designed to withstand extreme conditions, including operating temperatures down to –20 °C. The system is completely waterproof (IP66), shockproof, and designed to provide reliable power anytime, anywhere.

WHAT SETS OUR PRODUCTS APART

FlexiBatt – universally applicable. FlexiBatt can be used in a variety of ways and is highly flexible. Its application is not limited to the operation of Euroheater devices. Thanks to its mobile and robust design, FlexiBatt is suitable for numerous areas of application, such as lighting, tools, mobile heating systems, camping and outdoor equipment, or emergency power supply. Developed and manufactured in Norway, FlexiBatt is a robust, high-capacity battery designed for use in extreme outdoor conditions. It was developed specifically to power the Euroheater 4D and other critical devices, combining advanced lithium-ion technology, proven durability, and excellent energy efficiency.

With a gross capacity of 2.4 kWh and a rated capacity of 2.3 kWh, FlexiBatt enables autonomous heating operation for up to 3–4 days at low settings, making it ideal for mobile applications where access to conventional power is limited or unavailable. Whether for military operations in cold climates, field research in remote areas, or disaster relief operations, this battery is a reliable plug-and-play power source.

The waterproof IP66-rated enclosure, shock resistance, and wide operating temperature range (-20°C to +45°C) ensure reliable performance in harsh environments. The device supports multiple outputs – including 12 V, 24 V, USB-A, and USB-C – and can be fully charged in just 2 hours using a 20 A charger with 230 V. Solar charging is also possible, increasing its versatility for off-grid use.
