Product overview
The SWIFT 45Ah from Enli Dongli is a solid-state battery cell intended for industrial drones, eVTOL aircraft and heavy-payload drones. It is presented as the launch flagship of the manufacturer's aviation-focused battery range. Its model-specific specifications give an energy density of 403±10Wh/kg, a voltage platform of 3.48V and an operating temperature range of -20 to 60°C. These figures describe the cell rather than a complete aircraft battery pack.
The SWIFT 45Ah specification gives a fast-charge rate of 0.8C, continuous discharge of 1C and a cycle life of at least 200 cycles at 0.5C charge and 0.5C discharge. A separate promotional description claims 4C continuous discharge, internal resistance of 1.5mΩ and a long-term storage temperature range of 15 to 35°C. The conflicting continuous-discharge ratings remain unresolved. Intended civilian applications for the wider battery range include logistics delivery, urban air mobility, industrial inspection, agricultural crop protection and emergency rescue.
