Overview

The original Unitree Go2 Charger is designed specifically for the Go2 robotic dog batteries. It offers stable and safe charging with eight-level protection and is available in two versions – Standard for regular charging and Fast for significantly quicker top-ups.

Two versions for different needs

• Standard: output 33.6 V / 3.5 A, full charge in approximately 2–4 hours (depending on battery capacity).
• Fast: output 33.6 V / 9 A, recharge in about 0.8–1.5 hours (standard 8000 mAh / extended 15000 mAh).

Compatible with both smart battery capacities for Go2: BT2‑05 (8000 mAh) and BT2‑06 (15000 mAh).

Safety and reliability

The battery’s integrated BMS and the charger work together to ensure: balanced charging, overcharge and short-circuit protection, temperature and overcurrent protection, deep-discharge protection, and load detection.

European version

An EU variant is available with 100–240 V / 50–60 Hz input and a plug for European sockets (type F).
