Engineered for tactical advantage
ARCTIC™ Battery Cells
South 8’s ARCTIC battery cells deliver critical reliability across the harshest environments, with industry-leading cold-weather operation down to -60 °C and proven high-temperature storage at +60 °C and 100% state-of-charge.
LiGas is a patented liquefied gas electrolyte that replaces conventional liquid electrolyte, significantly improving performance, safety and enabling extreme temperature range.
The cells and the proprietary LiGas electrolyte will be produced at South 8’s San Diego facility, providing defense customers with a domestically manufactured battery cell and a defined pathway toward meeting applicable National Defense Authorization Act (NDAA) sourcing requirements once those rules are finalized.
Developed and tested with support from US Army DEVCOM C5ISR, South 8’s ARCTIC battery cells are currently being evaluated in prototype battery packs for soldier portable applications.

The AE35 vs. Competitor Defense 18650s
AE35 outperforms all competitor cells at -20 ˚C and below
Energy Retention (Discharge)
Test conditions: 0.3C, Discharge 1D
South 8’s LiGas is a liquefied gas held under pressure, giving LiGas an ultra-low freezing point below –100 °C while Liquid Electrolyte weakens at 0 ˚C and freezes at -20 ˚C. This unique property ensures it stays fully functional even in the harshest of environments.
