The Go2 quadruped ships in several variants — Air, Pro, X, and EDU — and battery specs vary between them. Community documentation reports 8,000 mAh for the standard pack and 15,000 mAh for the EDU pack, but Unitree has not published an official battery datasheet.
Because specs vary by variant, match the battery to your exact Go2 model: check the nameplate on your current pack for the part number and voltage before ordering a replacement. When in doubt, buy from Unitree or an authorized reseller with the variant named explicitly.
Always match the exact model and revision — Unitree packs are not interchangeable across models. Buy OEM wherever possible; the battery management handshake is model-specific. For installation help, find a technician experienced with Unitree hardware.
Check current listings from sellers, or look up the official charging guidance before you buy.

Batteries are the riskiest component to go third-party on — wrong voltage, missing BMS communication, or poor cells can damage the robot or create a fire hazard. OEM packs are strongly recommended.
Runtime drops well below the original spec, the robot shuts off under load despite showing charge, the pack swells or runs hot, or charge times stretch far longer than when new. A swollen pack is a safety issue — stop using it.
