Not on the evidence available. In January 2024, Beijing-based Betavolt said its miniature nuclear battery could let drones that normally fly for about 15 minutes fly “continuously”—but the company made that claim conditionally, and reports did not document a drone flight powered by the battery. Its reported output, 100 microwatts, is a measure of very low electrical power, not proof that it can supply the much larger, immediate demand of drone motors.
What did Betavolt claim?
Betavolt’s statement, reproduced by Futurism, was: “If policies permit, atomic energy batteries can allow a mobile phone to never be charged, and drones that can only fly for 15 minutes can fly continuously.” The wording matters: the drone use was presented as a conditional possibility, not as a demonstrated capability. The reporting does not name the person who made the statement.
The Independent reported that Betavolt’s battery had entered pilot testing in 2024. Futurism likewise described it as being at the pilot stage. Those historical descriptions do not establish the product’s status today, and neither report provides an independent drone test. The reviewed sources also do not establish current sales, regulatory clearance, or independently verified performance.
Why a long-lasting battery may still be unable to power a drone
Energy and power answer different questions
Energy is the total amount available over time; power is how quickly it can be delivered. A source can produce a small amount of power for a long period, yet still be unable to meet a device’s high instantaneous demand. Drone propulsion requires enough power to run its motors, including during demanding flight conditions. A claimed long service life alone says nothing about whether the source can deliver that motor power.

What the reported output does—and does not—tell us
The Independent reported Betavolt’s claimed output as 100 microwatts at 3 volts. This is a company figure relayed in a 2024 news report, not an independently validated measurement in the sources reviewed. The report does not provide the power-demand measurements or an integrated flight test needed to show that the battery can propel a drone. It would therefore be misleading to turn the company’s reference to a roughly 15-minute drone flight into a verified flight-time comparison.
What kind of battery is it?
Betavolt describes its device as a betavoltaic battery: it converts energy from radioactive isotope decay into electricity. The Independent attributed the design to Nickel-63, while Futurism described nickel isotope material and diamond semiconductors. These are details reported about the company’s design, not independent inspection or validation of the hardware.

The Independent reported Betavolt’s claimed dimensions as 15 × 15 × 5 millimeters and its claimed service life as 50 years. Both figures were company claims reported in 2024. A small form factor and long claimed service life may be relevant to some applications, but neither establishes sufficient power for flight.
How to evaluate a continuous-flight claim
A useful assessment would need more than a battery’s stated lifetime. For any proposed power source, the key questions include:

- Output versus demand: Does it meet the drone’s peak and average power requirements?
- Performance over time: How does output change as the source ages?
- Integration: What are the complete system’s size, mass, packaging, and effect on the aircraft?
- Safety and permissions: What handling, shielding, and regulatory requirements apply?
- Evidence stage: Is there only a company announcement, an independent bench test, or a field demonstration of the integrated drone?
The reports reviewed establish a company claim and reported specifications; they do not establish an independent test or field demonstration of a Betavolt-powered drone.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.A separate Nickel-63 product announcement is not proof of Betavolt’s claim
In April 2026, NRD announced a different Nickel-63 betavoltaic product for ultra-low-power applications such as remote monitoring and sensing. NRD gives a typical output range of 5 to 500 nanowatts and a form factor of 20 × 20 × 12 millimeters. These are NRD’s figures for its NBV series, not Betavolt’s battery; the announcement does not demonstrate that Betavolt’s device can power a drone.
