On 19 August 2019, the compact 2.5 MW (3,400 hp) generator was run for the first time in Trondheim, Norway, before integration with an AE2100 turboprop from a Saab 2000 feeding the battery pack and a Siemens SP260D electric motor (with a 10 kW/kg power-to-weight ratio) replacing one Honeywell LF507 engine with a Rolls-Royce AE 3007 fan, through ...
In January 2020, Wright Electric revealed that it was constructing a 1.5 MW electric motor and 3 kV inverters intended to power a 186-seat Wright 1 aircraft with a range of at least 300 nmi (560 km) that could enter into service from 2030. Ground testing of the motor is planned for 2021 and flight testing for 2023.
The company claims that the battery packs have an expected lifespan of 1500 hours and cost US$7000 each, with the aircraft carrying 3-5 battery packs, giving two to two and half hours endurance. The batteries can be recharged in 3–4 hours from a 220 volt outlet.
Take-off is not allowed when battery state of charge (SoC) is below 50%. [2] The aircraft has a built-in continuous health-monitoring system displaying the estimated 'age' of the battery, and the battery must be charged using proprietary equipment. [2] The E-811 is the first certified electric aircraft motor and was certified by EASA on 18 May ...
The maximum take-off weight of the NXT is 1,200 kg. Rolls-Royce intend the battery, motors and control equipment in a production system to weigh the same as the regular engine and fuel tank in a conventional aircraft, [2] but the battery pack alone in the Spirit of Innovation currently weighs 1350 kg.

Larger aircraft have control surfaces that run on these backups as well. Aircraft batteries are either nickel-cadmium or valve-regulated lead acid type. The battery keeps all necessary items running for between 30 minutes and 3 hours. Large aircraft may have a ram air turbine to provide additional power during engine failures.
