High Energy Density UAV Battery Applications
Lightweight battery solutions provide higher total mission energy for fixed-wing and hybrid UAVs operating over long distances.
Lightweight design increases payload capacity per trip and reduces overall operating costs.
For 100–200kg heavy-lift drones, Herewin batteries deliver longer flight time, stable high-power output and faster turnaround for cargo transport and industrial UAV missions.
Semi-solid-state batteries provide extended endurance and high payload capacity—ideal for long-range rescue missions and safe personnel transport.
High-specific-energy batteries support vertical takeoff, transition, cruise, and landing while reducing total battery mass.
Ultra-high energy density batteries enable continuous surveillance missions exceeding 48 hours at high altitudes.

Need Longer Flight Time Without Adding Battery Weight?
Increasing battery capacity alone may also increase aircraft weight and power consumption. Our engineers evaluate specific energy, battery weight, discharge performance, voltage sag, thermal behavior, and propulsion-system compatibility together to identify a more effective UAV battery solution.
FAQs
A high energy density UAV battery stores more energy per unit of weight or volume than a conventional drone battery. Higher specific energy can help extend flight endurance, reduce battery mass, or increase available payload.
Gravimetric energy density is normally measured in watt-hours per kilogram, or Wh/kg. It can refer either to the cell level or the complete battery pack level. Pack-level energy density is lower because the enclosure, cable, connector, BMS, insulation, and structural components add weight.
Herewin currently provides cell-level energy density platforms ranging from approximately 320 Wh/kg to 400 Wh/kg, depending on the cell technology and product configuration. The final pack-level energy density must be calculated according to the enclosure, BMS, connector, cable, and structural design.
