Unitree R1 Battery

Two numbers on a label tell most of the story of the Unitree R1 Battery: 33.12V and 6000mAh, or 199Wh when expressed as energy. They describe the dedicated power pack for the Unitree R1 robot, and they are the figures a lab manager, an integrator or an instructor should have in hand before planning a day with a humanoid platform.

The Unitree R1 Battery is available through this page, by quotation.

Background

Unitree and the idea of a purpose-built pack

Unitree Robotics is known for legged and humanoid robots, and the company builds more than the robots themselves. It also makes the parts that keep them running, including the packs, chargers and accessories around each platform. Each robot in the range has its own battery, and the pack is treated as part of the machine rather than as an afterthought. You can see the wider family of packs in our Batteries category, where batteries for other Unitree robots sit alongside this one. The G1 humanoid, for example, has its own pack, the Unitree G1 Rechargable Lithium-ion Battery (BT2-36). Packs are matched to the robot they were designed for, so it is worth checking the model name before ordering.

What sets this pack apart

Unitree builds the Unitree R1 Battery on next-generation battery technology and manages it with its proprietary advanced Battery Management System (BMS). The BMS is the electronics layer that watches the cells, balances them and decides when to cut power. It is what turns a block of cells into a pack that a robot can safely depend on. Around the cells sits an ultra-high-strength engineering plastic casing, which protects them from impact in accidental drops. For a pack that is regularly removed, carried and refitted, that protection matters as much as the capacity figure.

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 charge time, the runtime per charge for this pack, the operating temperature range, the cycle life, the connector type or whether a charger is included; they are confirmed at quotation.

What does the 199Wh rating mean in practice?

Capacity can be read two ways. Milliamp-hours, here 6000mAh, tell you how much charge the pack holds at its rated voltage. Watt-hours, here 199Wh, express the same pack as energy, which is the better figure for comparing it with packs of different voltages. Both are printed for the Unitree R1 Battery, and they agree with the rated voltage of 33.12V.

What the figures do not give you is a session length. How long an R1 robot runs on one pack depends on what it is doing. If your plan depends on a given session length, mention it when you request a quotation, and plan to test the first pack in your own routine before you settle on how many you need.

How does the seven-level protection help a working team?

The pack lists seven protections: battery load detection, balanced charge, overcharge protection, charging temperature protection, charging current protection, short circuit protection and over discharge protection. Several of these act during charging, which is when a pack in a busy lab is most likely to be treated carelessly. Others act while the robot is drawing power. Together they mean the protective work is built into the pack rather than left to the operator.

This does not replace good habits. Cases still crack, and a pack that has taken a hard knock deserves a careful look before it goes back into a robot. But the combination of the BMS and the impact-resistant casing gives teams a reasonable base to build a handling routine on.

Who is the Unitree R1 Battery for?

The first group is owners of an R1 robot who want a second pack so that one can be charged while the other is in use. Anyone who has run a long demonstration or a full teaching day knows that a single pack sets the pace of the whole session.

The second group is research and education teams. A university lab or training center usually shares a robot among several people, and the battery is the part that gets swapped most often. A casing that tolerates accidental drops suits that kind of shared use.

The third group is integrators and evaluation teams who are testing the R1 for a specific job. They need to know the voltage, the capacity and the physical size of the pack, and this page lists all three. If you are looking for a battery for a different Unitree robot, do not order this one. Browse the Batteries category or the Humanoid Accessories category instead.

What is the Unitree R1 Battery used for?

1. Powering the R1 robot. It is the dedicated energy source Unitree specifies for this platform.
2. Swapping during long sessions. A spare pack lets the robot get back to work while the first one recharges.
3. Classroom and lab teaching. Students can run exercises on the robot with a pack that is built for repeated handling.
4. Research trials. Teams studying motion, perception or interaction need steady power across repeated test runs.
5. Demonstrations and events. Showing the robot to visitors requires a charged pack ready at the start of each session.
6. Replacement over time. When a pack has been in service for a long period, a new one keeps the robot available.

Frequently Asked Questions

Which robot does the Unitree R1 Battery fit?

It is the battery for the Unitree R1 robot. Do not assume it fits other Unitree models, which have their own packs.

What are the voltage and capacity?

The rated voltage is 33.12V and the capacity is 6000mAh, which is 199Wh.

How big is the pack?

The size is 93.9mm * 90.3mm * 159mm.

What protections does it have?

It has seven levels of safety: battery load detection, balanced charge, overcharge, charging temperature, charging current, short circuit and over discharge protection. These are managed by Unitree's proprietary BMS.

How long does it run the robot?

Runtime depends on what the robot is doing. Test the pack in your own routine, and mention your session-length needs when you request a quotation.

Does it come with a charger?

Charger and connector details are not listed among the figures on this page. Ask about them when you request a quotation.

Where can I buy the Unitree R1 Battery and what does it cost?

You can buy it through this page by requesting a quotation. We do not list a price here; the quotation covers the cost, delivery and support for your order.

Summary

Two printed numbers, 33.12V and 6000mAh, lead to a pack that is small enough to hold, protected by seven safety levels, and managed by Unitree's own BMS. It is made for the R1 robot and no other.
