What Figure reports about runtime and charging

Figure lists a 2.3 kWh capacity and five hours of runtime at peak performance for the Figure 03 battery. The company also specifies 2 kW fast charging with active cooling and reports a 78% cost reduction from the Figure 02 pack. We treat all three as manufacturer-reported specifications.

Figure says three generations of development raised battery energy density by 94%. Its first-generation pack sat in an external backpack; Figure 03 moves the battery into the torso and brings its engineering and production into the company’s BotQ facility.

A structural pack inside the torso

The enclosure uses stamped steel, die-cast aluminium and structural adhesives. Figure says this construction makes the battery part of the robot’s torso structure and lets the pack survive a one-metre drop onto concrete in any orientation.

Cooling hardware is built into the die casting, according to Figure. The company says this design reduces thermal resistance and local heat generation for forced-air fast charging. It also uses components that perform multiple jobs, which Figure says raises the cell-to-pack ratio while cutting cost and complexity.

Safety layers and certification status

Figure describes its custom battery-management system as using sensors, switches and fuses against overcharge, excessive discharge, high temperature and external short circuits. At pack level, the company says insulation, heat distribution and a flame-arresting vent are intended to stop a failing cell from spreading heat or flame.

In a company-run fault-injection test, Figure says it deliberately heated one cell into thermal runaway. The reported result was no external flame and reduced propagation between cells; this is Figure’s test report, not an independent benchmark.

The certification wording matters. Figure’s battery-development post described the pack as being in the certification process for UN38.3 and UL2271. Its Figure 03 launch page separately says the battery achieved UN38.3 certification. Those statements support a completed UN38.3 status and an UL2271 target, not a claim that both certifications were complete.

Designed for BotQ production

Figure says the pack was developed for BotQ’s first manufacturing line, which is designed for capacity of up to 12,000 humanoids per year. To pursue that rate, the company shifted parts from machining toward die casting, stamping, injection moulding and dip moulding. The capacity figure describes the line’s stated ceiling, not reported annual output.
