Core Features & Advantages

Sub-Zero Performance

Specifically optimized for ultra-low temperature environments, maintaining over 70% capacity retention even at -40C.

Extreme Discharge Rate

Capable of 3C continuous and 5C pulse discharge (75A), providing heavy-duty power for high-intensity equipment.

Validated Reliability

Passed 1.5m concrete fall tests, low-pressure (vacuum) tests, and external short-circuit protocols with zero fire or explosion risk.

Low Thermal Loss

With internal resistance < 3mOhm, the cell minimizes heat generation during high-power operation, protecting sensitive electronics.
