Unitree 9000mAh Battery for A2 Quadruped Robot

A2 9000mAh Battery

The A2’s power comes from a high-capacity 9,000 mAh battery (˜ 453.6 Wh) — a compact but potent energy pack engineered for autonomous robotics. This battery alone provides enough juice to power locomotion, sensors, actuation, and compute on a single-charge mission. For extended operations, A2 supports a dual-battery setup: two 9,000 mAh modules combine for 18,000 mAh (˜ 907.2 Wh), giving the system the endurance required for longer deployments.

Single-cell power: 9,000 mAh (˜ 453.6 Wh) battery — compact footprint, flexible for modular deployment or as a spare pack.
Dual-bay ready: supports two batteries in parallel (total 18,000 mAh / ˜ 907.2 Wh), enabling extended runtime or back-to-back missions via hot-swap capability.
