Available with welding or nut terminals to suit various installation needs, with an interactive 3D model view.
The label shown on the battery cell is for visual demonstration only. The actual product will usually not have this label, only the essential numbering or identification.

Due to its unique properties, our NMC battery cell is widely used in fields requiring high energy density and strong power output:

Delivers the high energy density for maximum flight endurance and the high C-rate power for demanding drone payloads.

Our cells meet both BEV demands for maximum range (high energy density) and HEV needs for instant power and regeneration (high C-rate).

Powered by superior energy density, our cells deliver greater power and extended range for high-performance electric yachts and hydrofoils.
Our products undergo strict testing and comply with multiple international standards to ensure quality and safety.

*Certification status may vary depending on region or project requirements. Relevant test reports or assistance for market-specific certification can be provided upon request.
