This is one battery pack for the Unitree A2, the industrial quadruped built for inspection, logistics and emergency work. Each pack holds 9000 mAh (453.6 Wh). The A2 carries two of them side by side in dual battery slots, for 18000 mAh (907.2 Wh) in total, so what you order here is a single pack, not the pair.
The dual-slot design is what makes a spare worth having. The two packs work in parallel and are hot-swappable: one can be changed while the other keeps the robot powered, so a charged spare lets a patrol or inspection round carry on without a shutdown. With both packs fitted, the A2 is rated for more than 5 hours of continuous walking unloaded (about 20 km) and more than 3 hours carrying 25 kg (about 12.5 km).
It is also the part to order when one of the robot's own packs has aged and needs replacing. It is not the battery for the smaller AS2, which uses its own Standard (8000 mAh) and Long Range (15000 mAh) packs, sold separately. The wheeled A2-W is specified with the same 9000 mAh pack; we confirm fitment against your unit before you order.
Pack weight, dimensions and charging time per pack are confirmed at quote, together with the charging equipment you already run.
