Not on the evidence available. Beijing-based Betavolt said in January 2024 that its miniature betavoltaic battery could enable drones limited to about 15 minutes of flight to fly continuously, “if policies permit.” Reports described a pilot-stage product, not an independently demonstrated drone. The key unresolved issue is power: a source that produces a tiny amount of electricity for decades is not automatically capable of supplying the much larger, immediate demand of propulsion.
What Betavolt actually claimed
Betavolt described a miniature battery that converts energy from radioactive isotope decay into electricity through betavoltaic conversion. Futurism reported the company’s description of nickel isotope material paired with diamond semiconductors; The Independent attributed the design to Nickel-63. Those material details are company claims relayed by news reports, not independent inspections of the hardware.
Futurism reproduced the company’s conditional statement: “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 statement was not attributed to a named executive, and the reports did not document a drone flight powered by the battery.
The published specifications
The Independent reported the following figures from Betavolt in 2024. They should be read as claimed specifications, not independently validated performance results.

Why long life is not the same as enough power
Battery discussions often mix up energy and power. Energy is the total amount available over time; power is the rate at which it can be delivered at a particular moment. Betavoltaic cells can produce a small, steady electrical output as an isotope decays. That can suit sensors or other ultra-low-power electronics that operate for years without a battery replacement.
A drone’s propulsion system must deliver substantially greater instantaneous power to start motors, climb, maneuver and remain airborne. A claimed 100 microwatts is 0.0001 watt. Nothing in the cited reports shows that Betavolt’s device can supply the peak or continuous power required by a drone’s motors, either directly or through an energy-storage system. A long service-life claim therefore cannot establish continuous flight.

With QC3.0/5V3A and single USB-C input, it takes about 240 minutes for three batteries (around 80 minutes per battery).
What has—and has not—been demonstrated
Reported by the company
- A Nickel-63-based miniature betavoltaic design, according to the reporting.
- A claimed 100-microwatt, 3-volt output in a 15 × 15 × 5 mm package.
- A claimed 50-year service life.
- A conditional proposal that such batteries could let short-endurance drones fly continuously.
Not established by the available reports
- An independently verified drone flight using the battery.
- Motor-start, hover or maneuvering power measurements.
- Independent laboratory validation of the output, lifetime or packaging.
- Current commercial sales, consumer availability or unrestricted regulatory approval.
The reports placed the product at a pilot stage in 2024. They do not establish Betavolt’s status as of September 28, 2026.
How another 2026 betavoltaic announcement fits
NRD announced a separate Nickel-63 betavoltaic product in April 2026 for ultra-low-power uses such as remote monitoring and sensing. NRD gives its NBV series a typical output range of 5 to 500 nanowatts and a 20 × 20 × 12 mm form factor. This is a different company and product; the announcement neither verifies Betavolt’s device nor supports the drone-flight claim.

What would be needed to substantiate continuous drone flight
A credible demonstration would need more than an isotope and a small package. Readers should look for:
- Independent measurements of voltage, average output and peak output under load.
- A complete power budget for motors, flight controls, communications and energy storage.
- A documented flight test showing takeoff, sustained hover and maneuvering.
- Mass, shielding and thermal data for the packaged radioactive source.
- Applicable transport, handling and aviation approvals for the intended country and use.
Safety, regulation and availability remain open questions
Betavolt’s quoted statement itself included “if policies permit,” signaling that regulation is part of the proposal. The available reports do not identify approvals, certification, retail channels or rules governing consumer drone use. A radioactive-source battery would also require its packaging, transport and end-of-life handling to be assessed, not just its electrical output.

Bottom line for drone owners
Betavolt’s battery is a reported betavoltaic concept with an impressive claimed lifetime and very low output. The company’s continuous-drone language is conditional, and no independent flight demonstration was documented. Until a tested system shows that the source can meet real propulsion loads and has the necessary approvals, it should be treated as a proposal—not a battery that can currently keep a consumer drone in the air indefinitely.
