3ME Technology and South 8 Technologies Sign Letter of Intent to Advance Extreme Cold‑Weather Battery Solutions for Defense
Under the agreement, South 8 will supply LiGas battery cells at production scale, which enable operation between ‑60 °C (-76 °F) and +60 °C (140 °F), and 3ME will integrate them into its EdgeVOLT™ battery solution. The battery systems are expected to be deployed in extreme environments, including sustained Arctic conditions. The collaboration targets defense applications requiring reliable, ultra-safe, portable power in austere environments.
South 8 Technologies Secures $11M in Additional Funding to Accelerate LiGas Battery Production for Defense and Aerospace
Galvion and South 8 are dedicated to using advanced battery technology to further address the challenges faced by today’s warfighter. As modern military operations extend into increasingly harsh and unpredictable environments, particularly the Arctic and other cold-climate theaters, limitations in today’s energy solutions become clear. The LOI establishes the framework for cooperative innovation, knowledge exchange, and field-focused testing to accelerate customers’ operational readiness in sub-zero temperatures.
