When it may not be suitable

This power source is exclusively designed for compatibility with the Unitree B2 robotic platform and is not suitable for standard consumer electronics, unrelated robotic models, or applications requiring different voltage specifications. It is also not intended for use outside the specified charging and discharging temperature limits.

Key specifications

  • Voltage: 58 V
  • Capacity: 45 Ah
  • Rated energy: 2250 Wh
  • Built-in management system: BMS
  • Discharge temperature range: -20°C to 50°C
  • Charging temperature range: 0°C to 40°C
  • Compatibility: Unitree B2

How to use

Ensure the Unitree B2 robot is powered off before installing or removing the battery. Securely insert the high-voltage power source into the designated battery compartment of the robot, ensuring all physical and electrical connections are properly engaged. Monitor the battery status through the integrated BMS and device interface during operation. When recharging, connect the battery only to compatible charging equipment within the approved temperature range of 0°C to 40°C to maintain longevity and safety.

What to consider before purchase

  • Verify that your robotic platform is the Unitree B2 model
