This is the smart battery for the Unitree H2, the 182 cm full-size humanoid: a quick-release pack of 15 Ah and 0.972 kWh, rated 64.8 V with a 75.6 V charge limit. It slides into the battery slot in the side of the robot, carries its own handle and latch, and runs the H2 for about 3 hours. Fast walking, carried loads, bent-leg standing and slopes shorten that.

Each H2 comes with one battery. A second one is what turns a 3-hour session into a working day: the H2 charger refills a pack in about 2 hours 40 minutes, so two packs can alternate, one in the robot and one on charge. The change is made with the robot suspended on its protective stand and powered down, and the pack is always charged outside the robot.

The pack manages itself. Its battery management system balances the cells and protects against overcharge, over-discharge, short circuit, charging over-current and charging below 0 °C or above 50 °C; four LEDs show the charge level and any fault. It switches on only when it is seated in the robot, and a new pack leaves the factory in shipping mode, activated by its first charge.

It fits the biped H2 range: the H2, H2 EDU and H2 Plus all use this 15 Ah quick-release pack. It is not the battery for the wheeled H2-D, which runs on its own 48 V base batteries, and fitment on the H2-A upper-body versions is confirmed at quote. Pack weight and cycle life are confirmed at quote too.

Key Capabilities

• 15 Ah, 0.972 kWh: Rated 64.8 V with a 75.6 V charge limit, for about 3 hours of H2 operation.
• Quick-release design: The pack slides into the side of the robot and is carried by its own handle.
• Built-in battery management: Cell balancing plus overcharge, over-discharge, short-circuit, over-current and charging-temperature protection.
• Four-LED status display: Shows the charge level and signals any protection fault.
• Load-detection safety: The pack switches on only when seated in the robot and powers off if it is removed while on.
