Nyobolt battery delivers 10:1 run-to-charge ratio
Agility Robotics has selected Nyobolt as its exclusive ultra-fast charging battery technology partner for its Digit 5 humanoid robot, with the new Nyobolt battery delivering 90 minutes of runtime from a full recharge that takes just nine minutes. The partnership, announced on October 15 and disclosed by Nyobolt through its own newsroom the same day, achieves a 10-to-1 run-to-charge ratio, a fivefold improvement on the 2-to-1 ratio of the previous-generation Digit 4. The company said the rapid-charge capability is designed to keep Digit working through more than two full shifts in a single day, enabling more than 20 hours of productive operation within a 24-hour period. Charging downtime has long been identified as one of the key constraints on the commercial deployment of humanoid robots, and the Nyobolt system is engineered specifically to remove that bottleneck in demanding industrial environments. The companies said the system addresses downtime, which they identified as a key constraint on robot utilisation. The announcement was made jointly by the two companies alongside Agility’s unveiling of the Digit 5 platform.
What the upgrade means for warehouse operators
For customers in warehouses, distribution centres and manufacturing facilities, the economics of humanoid robots depend heavily on utilisation: every minute a robot spends tethered to a charger is a minute of lost productivity. By compressing recharge time to nine minutes while extending runtime to 90 minutes, the Nyobolt battery allows operators to cover more than two full shifts per robot with minimal interruption. Agility said the system combines rapid charging with long cycle life and reduced weight, attributes that matter in machines where actuators, compute units and sensors compete for the same limited space. The company described the battery as one of the pieces that makes Digit 5 ready for full-scale operation, reflecting a broader industry recognition that power systems are as decisive as locomotion or manipulation software in determining whether humanoids can earn their keep on the factory floor. That performance leap is central to the Nyobolt battery value proposition for fleet operators weighing large humanoid deployments.
Digit 5 and the road to full-scale deployment
Digit 5 was recently unveiled as Agility’s first humanoid robot designed for cooperatively safe work at scale, allowing it to operate in close proximity to people, a significant step beyond the caged or segregated deployments typical of earlier industrial robots. Daniel Diez, chief business officer of Agility Robotics, said that for customers, Digit’s uptime is the business case, adding that Digit 5 would deliver more than 20 hours of productive work in a 24-hour day, more than two full shifts, a gain he said materially improves both the value customers get from each robot and the economics of deploying a humanoid fleet. Sai Shivareddy, co-founder and chief executive of Nyobolt, said Digit 5 needs more power from a smaller, lighter pack in environments where reliability is not optional, and that Agility had set an exceptionally high bar for what a battery must withstand in live warehouse and manufacturing settings. Both executives framed the Nyobolt battery as a decisive step towards making humanoids economically viable at scale.
Why the Nyobolt battery partnership matters
The announcement comes as Agility moves towards a public listing, with the company pursuing a business combination with Churchill Capital Corp XI targeted for closing in the fourth quarter of 2026 and a planned Nasdaq listing under the ticker AGLT. Early access to Digit 5 units fitted with the Nyobolt battery is expected to begin in the first half of 2027, followed by broader availability over the subsequent six to nine months for industrial operators. Analysts say the Nyobolt battery partnership could become a template for how robotics firms solve the power problem. Investors and customers alike will be watching whether the promised uptime figures hold up in real-world deployments, since the business case for humanoid fleets rests on sustained, multi-shift operation rather than demonstration performance. If the Nyobolt battery delivers on its 10-to-1 run-to-charge promise at scale, it could set a new benchmark for power systems across the fast-growing humanoid robotics industry, where every rival is grappling with the same fundamental trade-off between capability, weight and time on charge.
