Agility Robotics picks Nyobolt for fast-charging battery in Digit 5 humanoid
Agility Robotics has named Nyobolt as the technology provider for the fast-recharge battery system in Digit 5, its humanoid robot. According to Agility, the system lets Digit work more than 20 hours in a 24-hour day.
- Agility Robotics selected Nyobolt as the battery technology provider for its Digit 5 humanoid robot.
- The new battery gives 90 minutes of runtime and a 9-minute charge, a 10:1 run-to-charge ratio versus 2:1 for Digit 4.
- Agility says Digit 5 can work more than 20 hours in a 24-hour day.
- Early access is expected in the first half of 2027, with wider availability over the following six to nine months.
- Agility expects to go public via a Churchill Capital Corp XI deal closing in the fourth quarter of 2026.
A battery built around uptime
Agility Robotics, which describes itself as a leading humanoid robotics and physical AI company, said Nyobolt's high-power, ultra-fast charging technology powers one of Digit 5's most significant upgrades. Digit 5 was recently unveiled as the company's first humanoid robot designed for cooperatively safe work at scale, meaning it can operate in close proximity to people.
The new battery system delivers 90 minutes of runtime and charges in just 9 minutes, according to Agility. That gives a 10:1 run-to-charge ratio, up from the 2:1 ratio of Digit 4. The company says this is designed to enable more than two shifts in a single day.
Daniel Diez, Chief Business Officer of Agility Robotics, framed the change in commercial terms. "For our customers, Digit's uptime is the business case," he said, adding that Digit 5 will deliver more than 20 hours of productive work in a 24-hour day.
What Nyobolt brings
Agility says Nyobolt's battery technology is built for demanding industrial conditions and combines fast charging, exceptional cycle life and reduced system weight. By removing what Agility calls the power bottleneck that has historically constrained autonomous robot fleet economics, the system targets a key limit on robot utilization: downtime.
Sai Shivareddy, Co-founder and CEO at Nyobolt, said the technology was chosen because "Digit 5 will need more power from a smaller, lighter pack, in environments where reliability isn't optional." He added that Agility set an exceptionally high bar for what a battery has to withstand in live warehouse and manufacturing environments.
Nyobolt, founded in 2019, describes itself as a pioneer in high-power, fast-charging energy solutions. Its stated focus areas include AI datacenters, physical AI applications such as robotics and humanoids, and mobility.
Availability and the road to going public
Early access to Digit 5 equipped with Nyobolt's battery technology is expected to begin in the first half of 2027. Availability is then expected to increase over the following six to nine months for manufacturing, warehouse and distribution operators.
Agility is also preparing to become a public company through its previously announced business combination with Churchill Capital Corp XI (Nasdaq: CCXI). The deal is expected to close in the fourth quarter of 2026. The combined company would operate as Agility Robotics and is expected to trade on Nasdaq under the ticker symbol "AGLT."
What it means for customers
For operators weighing humanoid robots, charging time directly affects how much work a robot can do. Agility argues that the new battery improves the value customers get from each unit and the economics of running a humanoid fleet. The company says the result is a potential advantage for customers who can target longer operating windows, more productive shifts and more demanding task sequences.
The performance figures are expectations stated by the company, and the release describes them as forward-looking. Agility says its robots have logged more than 65,000 hours of real-world operation, and it pairs that experience with the new battery to strengthen Digit's case in warehouse, distribution and manufacturing work.
