Agility picks Nyobolt fast-charge batteries for Digit 5

KEY FACTS

  • Agility Robotics has selected Nyobolt fast-charge battery technology for its Digit 5 humanoid robot.
  • The battery delivers 90 minutes of robot runtime from a 9-minute charge.
  • Digit 5 has a charge-to-discharge duration ratio of 10:1, versus just 2:1 on the previous-generation Digit 4.
  • Robots equipped with this battery are slated to enter early trials in the first half of 2027.
  • Agility will merge with Churchill Capital Corp XI, with the deal expected to close in the fourth quarter of 2026.

PHYSIX OBSERVATION

Fast charging pulls robots out of the awkward "work two hours, charge for one" trap, and a 10:1 ratio is the real commercial threshold. But behind that 9-minute top-up are engineering trade-offs that make the battery pack smaller and lighter, and neither capacity nor cycle life has been disclosed, so reliability under real warehouse conditions remains an unknown. Competition in humanoid robots is shifting from showmanship to operational efficiency.
