FAQs

What is a high energy density UAV battery?

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.

How is energy density measured for UAV batteries?

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.

What energy density can Herewin UAV batteries provide?

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.
