Figure disclosed the battery architecture for its third-generation humanoid on 17 July 2025, specifying a 2.3 kWh pack designed to support five hours of operation and a 2 kW fast-charging system with active cooling. It said that energy density had increased by 94% across its battery generations, with the pack integrated into the robot's torso rather than positioned in an external module. The figures came from Figure's engineering disclosure and should be understood as design specifications, not independent duty-cycle measurements.
The pack forms part of the robot’s torso structure, replacing the bulkier external modules used on Figure 01. Figure describes stamped-steel and die-cast-aluminium components, its own battery-management system and a thermal design intended to contain cell failures. Integrating the battery into the body brings the mechanical packaging, electrical protection and cooling requirements into the same development programme.
Figure says the F.03 design reduced battery costs by 78% compared with F.02, alongside the increase in energy density across generations. The company is developing and manufacturing packs in-house at BotQ, allowing battery assembly to evolve with its robot production processes. Active cooling supports the stated 2 kW charging rate while the custom electronics monitor and manage the pack during operation and charging.
