Product information

Description

The Unitree B2 Heat-Resistant Battery BT2-12 40500 mAh 2041.2 Wh 50.4 V -40°C to 80°C Operating Range is a specialized power source engineered to support the demanding operational requirements of the Unitree B2 quadruped robot. Designed for deployment in extreme industrial settings, this battery ensures that the robotic system maintains continuous and stable performance where standard power solutions fail. By combining high energy density with advanced thermal management, it delivers dependable runtime even under severe ambient conditions.

Advantages

This high-performance battery stands out through its exceptional thermal resilience, accommodating operating temperatures spanning from -40°C to 80°C. Such a wide operational range allows the robotic system to function effectively in environments like hot desert regions or high-heat industrial plants, including steel mills. Furthermore, the rapid charging capability enables the unit to reach a full charge in approximately one hour using an appropriate charger, significantly cutting down operational downtime and enhancing workflow efficiency.

Suitable for

  • Powering the Unitree B2 robot in high-temperature industrial environments such as steel mills
  • Operating robotic systems in extreme cold or hot desert climates
  • Applications requiring minimal downtime through fast-charging battery solutions
  • Demanding tasks in heavy industry and specialized outdoor environments

When it may not be suitable

This battery is not designed for consumer electronics, standard domestic applications, or use with robotic platforms outside of the specified Unitree B2 model. Additionally, it may not be optimal for environments where charging infrastructure cannot support the specific voltage and current requirements for fast charging.

Key specifications

  • Designed for Unitree B2 robot
  • Rated voltage: 50.4 V DC
  • Charging limit voltage: 58.8 V DC
  • Rated capacity: 40500 mAh, 2041.2 Wh
  • Discharge temperature range: -40°C to 80°C
  • Charging temperature range: 0°C to 70°C
  • Full charge time: Approximately 1 hour with compatible fast charger

How to use

Installation requires inserting the battery securely into the designated compartment of the Unitree B2 robot, ensuring that all physical and electrical connections are properly engaged. Prior to charging, verify that the ambient temperature falls within the specified charging range of 0°C to 70°C. Connect the battery to a compatible charging system designed to handle the 58.8 V DC charging limit voltage. Always monitor the charging process according to the manufacturer guidelines to ensure safety and longevity.

What to consider before purchase

  • Verify compatibility with the specific robot model and existing charging equipment
  • Confirm that operational environments match the specified temperature parameters
  • Ensure access to a compatible charger capable of supporting the rapid charging specification
  • Evaluate the power requirements of planned industrial tasks and applications

Usage recommendations

Always adhere to the specified temperature ranges for both charging and discharging to prevent degradation and maintain optimal battery performance. Use only compatible charging equipment designed for this specific battery model to ensure safety and prolong service life.

Product comparison

This product page focuses on the Unitree B2 Heat-Resistant Battery BT2-12, which is specifically engineered to power the Unitree B2 quadruped robot in harsh environments. As alternatives, several other original Unitree brand components and accessories are examined: replacement rubber foot pads for the Go2 robot, a foot accessory to convert the B2 robot into a walking configuration without wheels, a fast charger for Go2 batteries, a universal remote control for Unitree robots, and protective brackets for the Go2 EDU educational platform. The main distinction of the featured product is that it is a heavy-duty, high-capacity, and temperature-resistant power source designed for continuous industrial robot operation, whereas the compared items are peripheral hardware, maintenance consumables, charging devices, control units, or protective frames intended for different robot models or specific maintenance tasks.
