SWIFT Semi-Solid State Batteries
Commercial-Ready Semi-Solid State Cells | High Power | Scalable Manufacturing
The SWIFT platform is Enpower's flagship aerospace-grade semi-solid state battery, engineered for aviation applications — industrial drones, eVTOL, and heavy-load drones — with breakthroughs in lightweight design, flight range, temperature adaptability, and instant power response. With energy density up to 403 Wh/kg and over 3 million cells delivered, SWIFT is proven at industrial scale.
Key Benefits
Energy density up to 403 Wh/kg (flagship 45Ah) — 270–380 Wh/kg in mass production
Up to 10C peak discharge and 3C+ fast charging for high-power eVTOL and drone operations
Aviation-grade safety — passes nail-penetration and thermal-abuse tests: smoke, not fire
Wide-temperature operation: -40°C to 60°C — adapted to plateau and cold-region climates
Six core aviation cells (22, 26, 35, 39, 45 & 57Ah)
Industrial-scale manufacturing — 3 million+ cells delivered
Flagship — SWIFT 45Ah
SWIFT's first flagship cell is smaller and more compatible, with an energy density of up to 403 Wh/kg and internal resistance reduced to 1.5 mΩ, enabling longer drone flight times. It supports 4C continuous discharge for instant, powerful take-off, and its long-term storage temperature range is expanded to 15–35°C — enabling one-button wake-up even after prolonged inactivity.
Ideal For
Industrial drones, eVTOL systems and heavy-load drones, electric motorcycles, and commercial vehicles. The SWIFT pouch cells ensure our clients can fly further, longer, and safely with record-breaking Wh/L and Wh/kg energy density.
Higher power with less weight, across every Enpower Greentech battery line — advancing a low-carbon, net-zero future.
