The Unitree R1 Battery is the official quick-release smart lithium battery for the entire Unitree R1 humanoid robot series (R1 Air, R1, and R1 EDU). With 6000mAh/199Wh capacity, 33.12 V rated voltage, proprietary BMS, and seven layers of protection, it delivers approximately one hour of runtime and reliable, high-performance power.
The Unitree R1 Battery is engineered as the dedicated high-performance power source for Unitree's ultra-lightweight R1 humanoid robots. Featuring next-generation battery technology and Unitree's proprietary advanced Battery Management System (BMS), it supplies stable, powerful electricity to support agile bipedal locomotion, perception systems, and multimodal AI functions. With a rated voltage of 33.12V, capacity of 6000mAh (199Wh), and dimensions of 93.9mm×90.3mm×159mm, the battery is compact enough for the R1's lightweight design while delivering the energy needed for approximately one hour of continuous operation. Its quick-release mechanism allows rapid hot-swapping, minimizing downtime during research, demonstrations, or extended testing sessions.
Built for durability and safety, the R1 Battery uses an ultra-high-strength engineering plastic casing that protects the cells from impact in the event of accidental drops. It incorporates seven levels of protection: battery load detection protection, balanced charge protection, overcharge protection, charging temperature protection, charging current protection, short circuit protection, and over-discharge protection. Compliance with IEC 62133-2 and UN38.3 standards further ensures reliability for civilian robotics use. Fast-charging capability and long-lasting standby performance make it practical for both intermittent and continuous workflows.
This battery is fully compatible with all Unitree R1 models, including the R1 Air, standard R1, and R1 EDU. Whether you are running the lighter 20-DOF Air configuration or a fully equipped EDU platform, the same quick-release smart battery provides consistent power delivery. Adding a spare R1 Battery is the most effective way to extend operational time -- swap packs and keep working while the depleted unit recharges. As the official Unitree power solution, it maintains the robot's designed performance, safety margins, and ease of maintenance across the entire R1 family.
