Galvion, a manufacturer of soldier power and data management systems, announced on October 7, 2026, the launch of its new Nerv Centr SoloPack Arctic, an extreme-cold rechargeable battery designed for Arctic operations. The battery will make its debut at AUSA 2026 in Washington, D.C., from October 12–14.
The SoloPack Arctic was developed in collaboration with South 8 Technologies and is the first product from a partnership announced in November 2025. It integrates South 8’s ARCTIC AE35 18650 cell, which uses the company’s LiGas liquefied gas electrolyte technology. The cell is engineered to deliver power across a temperature range of -60°C to +60°C (-76°F to +140°F).
The battery retains the 98Wh form factor of Galvion’s original SoloPack battery. It weighs 1.2 lbs (544 g) and has an energy density of 178 Wh/kg.
According to Galvion, the AE35 cell also demonstrated in cell-level ballistic penetration testing the ability to evacuate electrolyte following penetration, reducing burn duration to seconds at the individual cell level and reducing the risk of propagation to adjacent cells.
Initial quantities of SoloPack Arctic will be deployed in upcoming U.S. Army field evaluations, including U.S. Army DEVCOM and the International Cooperative Engagement Program for Polar Research (ICE-PPR)’s Operation Mjölnir.
Jonathan Blanshay, founder and executive chairman of Galvion, said: “Arctic readiness is becoming an increasingly important requirement for the U.S. and allied forces, and reliable power is fundamental to operating effectively in those environments. Extreme cold exposes the limitations of equipment that performs well under normal conditions, so we need to ensure that the technologies soldiers depend on are ready to perform wherever the mission takes them.”
