Why Add the Unitree R1 Battery to Your R1?
The Unitree R1 Battery is the dedicated power pack for the Unitree R1 humanoid, built around next-generation battery cells and Unitree’s own proprietary Battery Management System (BMS) to deliver fast charging and long-lasting standby power. Full specifications are published on Unitree’s official product page.
Keeping a spare R1 Battery on hand lets research teams and integrators swap in fresh power between test sessions or demos instead of waiting out a full charge cycle, and its rugged engineering-plastic shell is built to protect the cells if the battery is accidentally dropped.

Key Features
- High-Capacity, Fast-Charging Cell: 6000 mAh / 199 Wh rated capacity at 33.12V, charging at up to 5.5 A for quicker turnaround between sessions.
- Unitree Battery Management System: Next-generation cell technology paired with Unitree’s own BMS for stable, reliable power delivery to the R1.
- Seven-Layer Protection: Battery load detection, balanced charging, overcharge, charging temperature, charging current, short-circuit, and over-discharge protection built in.
- Impact-Resistant Shell: Ultra-high-strength engineering plastic casing protects the battery cells if the pack is accidentally dropped.
- Certified Safety: Built to the IEC 62133-2 and UN38.3 standards covering lithium battery safety and transport.

Seven-Layer Safety Protection
The R1 Battery’s BMS continuously monitors battery load, charge balance across cells, overcharge state, charging temperature, and charging current, and cuts power on a short circuit or over-discharge condition — seven separate protection layers in total. Combined with the impact-resistant engineering-plastic shell, that makes the pack a safer fit for repeated lab handling, transport between sites, and everyday demo use than a bare, unprotected cell.

Compatible Robots
The R1 Battery is purpose-built exclusively for the Unitree R1 humanoid platform, including units such as the R1 Basic and R1 EDU Standard Edition. It is not designed for Unitree’s G1 or H2 humanoids, or for its quadruped platforms — confirm your robot model with our team before ordering.
Installation & Use Cases
The R1 Battery installs as a direct replacement power pack for the R1 humanoid, so a charged spare can be swapped in when the robot’s current battery runs low. Its 5.5 A charging current is built to shorten the wait between sessions compared with a slower charge cycle, and the seven-layer protection system is designed to keep charging and discharging safe under everyday lab and demo conditions.
This makes the R1 Battery a practical accessory for research labs, universities, and integrators running extended R1 test sessions, live demos, or multi-shift development work where minimizing downtime between charges matters. Keeping one or more spares on hand is a simple way to keep an R1 unit in continuous use throughout the day.
Who Should Consider This Upgrade
This accessory suits robotics labs, universities, and research teams running Unitree R1 units who want a fast-charging spare battery to reduce downtime between demos or test sessions. Because the R1 Battery is designed specifically for the R1 platform, confirm your robot configuration with our team before purchasing.
