Unitree H1 Battery (H1-BATTERY)

A humanoid robot is only as free as its last charge. The Unitree H1 Battery (H1-BATTERY) is the energy pack that keeps an H1 research platform working through demonstrations, trials and teaching sessions, and it is the part of the system a team notices most when it is missing. A rated capacity of 15000mAh, or 432Wh, sits behind a compact body built to power the robot.

The Unitree H1 Battery is available through this page, by quotation.

Background

Unitree Robotics and the H1 lineage

Unitree Robotics is a Chinese maker of legged and humanoid robots, best known for quadrupeds and, more recently, full-size humanoids. The H1 belongs to that humanoid line and is used by laboratories, universities and integrators who need a bipedal platform for work on locomotion, control and human-robot interaction. Two versions, H1 and H1-2, appear in the sources for this battery, and one set of figures covers the pack itself.

Around every robot platform sits a family of accessories: chargers, spare packs, docks and mounting parts. Unitree sells batteries for several of its robots, and each model has its own pack. For a team that owns an H1, the battery is the consumable at the center of daily operation. Teams that also run other Unitree platforms can browse the Unitree Batteries category to see how the packs differ from model to model.

Positioning and key technology

The H1 Battery is a DC 28.8V pack with a rated capacity of 15000mAh, or 432Wh. It charges at 9A. What sets it apart is the battery management system, which Unitree developed itself. A battery management system is the electronics layer that monitors and protects the cells inside a pack, and building it in-house lets the maker tune it to the robot it powers.

The pack measures 120mm * 80mm * 182mm. For a humanoid, where every part must fit a defined body envelope, those dimensions are the first thing an integrator checks. The package contains one Unitree H1 Battery 15000mAh.

Technical Specifications

Specifications as published by the manufacturer; confirmed against the datasheet at quotation.

The manufacturer has not published the weight, the cell chemistry, the cycle life, the operating temperature, the IP rating, the connector type or the charging time; they are confirmed at quotation.

What does the H1 Battery offer a team that already owns an H1?

The first answer is continuity. A humanoid platform is a significant investment, and the hours it can run are set by its pack. A spare H1 Battery gives a team a second source of energy, so one pack can charge while another is in use, and the working day is no longer tied to a single charge cycle.

The second answer is the match between pack and robot. The H1 Battery is Unitree's own pack for the H1, with a voltage of DC 28.8V and a capacity of 15000mAh. Because the battery management system is developed by Unitree rather than sourced as a generic part, the pack comes from the same engineering effort as the robot. For a lab that values predictable behavior, that is a practical reason to prefer the manufacturer's pack over an improvised one.

The third answer is clarity. The capacity is given in both milliamp-hours and watt-hours, so a purchasing officer or a safety reviewer can compare it with transport and storage rules without converting units. The charging current of 9A is also given, which helps when planning charging stations and the power supply that feeds them.

How should you compare the H1 Battery with other Unitree packs?

Unitree packs are not interchangeable across robots, and nothing here supports treating them as such. The Unitree G1 Rechargable Lithium-ion Battery (BT2-36) belongs to the G1 humanoid, the Unitree H2 Battery — Single Unit to the H2, and the Unitree R1 Battery to the R1. Each has its own figures and its own role. When you compare, begin with the robot you operate, and only then look at capacity and size.

A team that runs more than one Unitree platform should keep the packs labeled and stored separately. The H1 Battery figures on this page belong to this pack alone, and they should not be carried over to a sibling.

Who is the Unitree H1 Battery for?

Universities and research institutes are the clearest group. They run H1 robots for studies of walking, balance and manipulation, and long sessions with few interruptions produce better data. A spare pack shortens the gap between experiments.

Integrators and demonstration teams form a second group. When an H1 appears at a trade show, a customer visit or a public event, a charged reserve pack is cheap insurance against a stopped robot in front of an audience.

Educators are a third group. A classroom or training program that shares one humanoid among many students needs the robot ready each time a new group arrives. Spare packs make that routine manageable.

Finally, buyers who are replacing a pack at the end of its service life will find a single, clearly identified model here. Those who also need mounting and expansion parts for their humanoid can look through Humanoid Accessories. Buyers of a different Unitree robot should choose the pack named for that robot rather than this one.

What is the Unitree H1 Battery used for?

1. Powering the H1 humanoid. The pack supplies the DC 28.8V that the robot runs on during research and demonstration work.
2. Extending a working session. A second pack lets a team swap and continue instead of waiting for a recharge.
3. Replacing an aging pack. When an original pack is no longer meeting a lab's needs, a new unit restores the robot's running time.
4. Supporting teaching and training. Shared humanoids in classrooms stay available when a charged reserve is on hand.
5. Keeping demonstrations on schedule. Events and customer visits depend on a robot that does not stop early.
6. Building a charging routine. With the 9A charging current known, a team can plan its bench, its supply and its rotation of packs.

Summary

A humanoid robot stands or stops according to its energy, and the H1 Battery is where that energy comes from. This pack offers DC 28.8V, 15000mAh and 432Wh in a body of 120mm * 80mm * 182mm, charges at 9A, and is managed by a system Unitree built itself. For any team that wants its H1 to keep working, this page is the starting point.
