Power That Matches Your Robot and Your Mission

  • The Go2 Long Range Battery supports 9A fast charging — back to full in under 1.5 hours despite having nearly double the capacity of the Standard version.
  • Every battery includes Unitree's self-developed BMS — overcharge, overdischarge, short circuit, and balance charging protection built in, with real-time power display. The battery manages itself so you focus on the deployment.

FAQ

1

Are Unitree batteries interchangeable between robot models?

No — each Unitree robot uses a battery specific to its platform. The Go2, G1, B2, A2, As2, and H1 all use different batteries with different voltages, connectors, and BMS configurations. Using the wrong battery can damage the robot's power system. Always confirm your robot's exact model before ordering. If you're unsure, contact us and we'll confirm the right battery for you.

2

Go2 Standard vs Long Range — which one should I choose?

Both fit the Go2 robot dog and include Unitree's BMS, but serve different use cases:

  • Standard (8,000mAh, 29.6V): approximately 1–2 hours runtime with no load — suited to lab environments, indoor testing, and shorter missions with recharge breaks in between
  • Long Range (15,000mAh, 28.8V): approximately 3–5 hours runtime with no load — suited to field inspections, outdoor operations, and any deployment where stopping mid-task is not practical. Supports 9A fast charging: back to full in approximately 0.8–1.5 hours

If your robot regularly runs out before the task is done, the Long Range is the right choice. If your sessions are short and you recharge between them, the Standard is sufficient.

3

Does the Go2 Long Range fast charging require a special charger?

Yes — fast charging at 9A requires the compatible fast charger. Using a standard Go2 charger with the Long Range battery will charge the battery, but at the slower standard rate. If fast turnaround between sessions is important to your operation, make sure you have the correct charger. Contact us if you need help selecting the right charger alongside your battery.

4

What does Unitree's BMS protect against?

Every battery in this collection includes Unitree's self-developed Battery Management System, which provides:

  • Overcharge protection — stops charging automatically when the battery is full
  • Overdischarge protection — cuts power before the battery drops to a damaging level
  • Short circuit protection — instantly disconnects if a fault is detected
  • Balance charging protection — ensures all cells charge evenly for maximum lifespan
  • Storage self-discharge protection — manages charge level during storage periods
  • Real-time power display — visible battery level on the robot or controller at all times
5

Can I keep a spare battery and swap it during a deployment?

Yes — this is a common approach for teams running continuous operations. Unitree robots do not support hot-swapping (the robot must be powered down to swap), but a charged spare battery means you're back to the task in minutes rather than waiting for a recharge. For field teams, research operations, and security deployments where uptime matters, we recommend at least one spare battery per robot.
