Amprius 21700 Batteries

About

Amprius 21700 batteries are high-performance lithium-ion cells built for demanding, high-output applications. Amprius Technologies is a US-based battery company focused on advanced, high-performance cells. Its 21700 line is aimed at builds where energy and output matter — the kind of cells found in drones, aviation, and other applications where performance per gram is a priority. The 21700 format itself offers more capacity and energy headroom than the smaller 18650, making it a strong foundation for modern pack builds that need both runtime and power in a compact cylindrical cell.
