Unitree As2 Battery Standard Version 8000mAh

A walking robot is only as free as its last charge. The Unitree As2 Battery Standard Version 8000mAh is the pack that sets the working window for the As2 AIR, and it is the part of the kit that decides how long a team can keep the robot moving before the charger takes over. It is a plain, practical component, and for many crews it is the one that matters most on the day.

The product is available through this page, by quotation.

Background

Unitree Robotics and the As2 family

Unitree Robotics builds legged robots, and its quadrupeds are used by research labs, universities, inspection teams and integrators who need a machine that can walk where wheels struggle. The As2 line is offered in several versions: As2 AIR, As2 PRO, As2 X and As2 EDU. Each version is configured differently, and the battery is one of the items that changes from one version to the next.

In that lineup, the As2 AIR is the version that includes the standard 8000mAh battery. The PRO and EDU versions ship with a 15000mAh long-range battery and fast charging support. This page covers the standard pack, so it is the right reference for anyone running an AIR, or anyone who wants a second pack that matches the one in the box.

Where the standard pack sits

The standard battery is a lithium battery with a capacity of 8000mAh, supplied one per robot with the As2 AIR. It comes with a standard charger rated 50.4V 4A. The robot itself accepts a supply voltage range of 36V~50.4V, which tells you the charger output sits at the top of the range the robot works within.

Think of this pack as the baseline of the As2 power options. It gives the AIR a clear, predictable run time, and it keeps the robot simple to operate: one pack in, one charger, one working session. Longer sessions call for the long-range pack, which has a separate page, Unitree A2 Long Range Battery 15000mAh.

How does the standard battery differ from the long-range pack?

The difference is capacity and what follows from it. The standard pack is 8000mAh. The long-range pack is 15000mAh. On the As2 AIR with the standard battery, the unloaded battery life is about 2 hours of continuous walking, approximately 10km. The versions that ship with the long-range pack run about 4 hours of continuous walking, approximately 20km.

The charger changes as well. The standard pack is supplied with a 50.4V 4A charger, while the long-range configuration comes with a fast charger rated 50.4V 7.4A. A team choosing between the two is really choosing between a shorter working window with a simpler charging setup and a longer window with faster charging support.

Both run-time figures are for an unloaded robot. If your plan involves carrying a payload, talk it through with us when you request the quotation rather than assuming the unloaded number.

Is the standard battery enough for my work?

That depends on how you run the robot. A session of about 2 hours of walking suits classroom blocks, short test runs, controlled lab trials and demonstrations, where the robot returns to a bench between exercises and the charger is within reach. It also suits teams that keep a second pack on hand and swap between sessions.

Longer patrols, wider outdoor routes or full-day deployments push toward the long-range pack, which doubles the unloaded walking time. If you are unsure, tell us the route length and the number of hours you expect the robot to work, and we will go through the options with you when we prepare the quotation.

Who is the Unitree As2 Battery Standard Version 8000mAh for?

Owners of the As2 AIR are the first group. The AIR includes this pack, so a second unit gives them a spare for back-to-back sessions, or a replacement when the first pack is retired. Because the pack is matched to the AIR, it is the natural choice for anyone keeping that version running.

Universities and training centers are the second group. A shared robot used by several students in turn benefits from a spare pack that can charge while another is in use. Integrators and evaluation teams are the third: they often need a predictable, repeatable run time for testing, and a standard pack gives them a clear baseline.

If your work needs more time on a single charge, look at the long-range 15000mAh battery instead, since the PRO and EDU versions ship with that pack. You can also browse the wider Batteries category for packs made for other Unitree robots, and the Quadruped Accessories category for related equipment.

What is the Unitree As2 Battery Standard Version 8000mAh used for?

1. Powering the As2 AIR. It is the pack supplied with that version and runs the robot through its working session.
2. Keeping a spare ready. A second pack lets a team swap and continue instead of waiting on a charger.
3. Classroom and lab sessions. The unloaded walking time fits structured teaching blocks and short experiments.
4. Field trials and evaluation. It gives integrators a known baseline run time for testing routes and behaviors.
5. Demonstrations. A charged pack on hand keeps a show or a site visit on schedule.
6. Replacing an aged pack. When an existing standard battery reaches the end of its useful life, this unit takes its place.

Summary

A robot that walks for hours is a robot that is always one charge away from stopping, and the standard battery is what defines that limit for the As2 AIR. It is an 8000mAh lithium pack with a 50.4V 4A charger and an unloaded run of about 2 hours, approximately 10km. It is simple, matched to its robot and easy to plan around, and the long-range option is there when sessions need to run longer.
