As electrification advances and defence and security operations expand into more demanding and remote regions, activity in extreme environments is increasing. The Arctic, however, presents unique challenges for battery technology. With temperatures frequently dropping below –20°C, conventional lithium-ion batteries face significant performance limitations, including reduced capacity, slower charge acceptance, and increased internal resistance.
For defence forces, security installations, research facilities, and critical infrastructure operating in these conditions, energy reliability is not optional – it is mission-critical. Arctic performance is not simply a matter of efficiency; it directly impacts operational readiness, situational awareness, communications resilience, and the integrity of security systems. In these environments, power systems must be engineered not only for endurance and efficiency, but for survivability, rapid deployment, and uncompromised performance under sustained cold stress.
How Extreme Cold Affects Battery Performance
Low temperatures significantly affect battery chemistry. In lithium-based batteries, cold conditions slow down electrochemical reactions, increase internal resistance and reduce available capacity. Charging performance is also impacted, and without careful system design, operation at very low temperatures may lead to reduced lifespan or operational limitations.
Below –20°C, many conventional lithium-ion batteries experience severe performance degradation. In extreme cases, they can become nearly non-functional without additional thermal management solutions. This adds complexity and can compromise overall system efficiency.
In harsh Arctic applications, standard solutions are simply not enough.
Celltech Arctic Battery System – Engineered for Extreme Conditions

Celltech Arctic Battery systems with 12V, 48V and 24V output options
Celltech Solutions’ Arctic Battery System product family consists of LFP-based energy solutions engineered for extreme environments and mission-critical operations. Designed for reliable performance in low temperatures and harsh conditions, the product family supports both portable field applications and fully integrated rack-mounted installations.
Arctic Battery Systems are equipped with advanced heating control to maintain optimal operating temperatures in sub-zero conditions, reinforced insulation for improved thermal stability, and intelligent battery management that prevents deep discharge and protects long-term system integrity.
Portable Systems
Designed for dismounted teams and light tactical vehicles, battery systems deliver safe and silent power for drones, radios, ISR equipment, medical devices and electronic subsystems.
With 12V, 24V and 48V output options, high vibration resistance and discharge capability down to –30°C, the system ensures dependable performance in demanding field conditions. Safe LFP chemistry allows close-proximity use, while smart power distribution protects connected equipment.
The result is extended mission endurance, silent watch capability and improved operational mobility.
Rack-Mounted Systems
For command posts and vehicle-integrated installations, the battery system is available as a 19-inch rack-compatible energy system with integrated pure sine wave 230VAC output or as a fully vehicle-integrated command power solution.
These systems support C5 command and control equipment, tactical servers, secure communications and multi-screen operator consoles. Designed for seamless transition between vehicle and battery power, they provide continuous operation during engine shutdown and reduce reliance on generators.
The outcome is reliable, low-signature power supply and enhanced mission resilience in contested and extreme environments.
Shaping the Future of Mission-Critical Power in Extreme Environments
As electrification advances and defence and security operations expand into more demanding and remote regions, the ability to operate reliably in extreme climates will become increasingly important. The Arctic region serves as a demanding benchmark for next-generation power solutions, pushing the limits of performance, safety and durability.
At Celltech Solutions, we see challenging environments not as obstacles, but as opportunities to engineer better solutions. By combining experience, continuous development and rigorous validation, we are committed to designing battery systems that deliver dependable performance — regardless of operational conditions.
