Anker SOLIX C2000 Gen 2 Expansion Battery Features

2,048Wh That Doubles Your Capacity

The battery holds 2,048Wh, the same as the C2000 Gen 2 itself, so the pair gives you 4,096Wh for longer outages and trips. The expansion battery adds capacity, and the C2000 Gen 2 still supplies the AC output, rated at 2,400W continuous with a 4,000W peak.

LFP Cells Rated for 4,000 Cycles

Anker builds it with LFP batteries and its InfiniPower technology, rated for up to 4,000 cycles at 80% capacity. Anker describes that as every day for 10 years. Actual battery life varies with use, temperature and conditions.

One Cable to the C2000 Gen 2

The included battery-to-host cable links the battery to the expansion battery port on the C2000 Gen 2. Anker designed it exclusively for the C2000 Gen 2, and it isn't compatible with the Anker SOLIX F2000.

5-Year Full-Device Warranty

Anker covers the BP2000 Expansion Battery (Gen 2) with a 5-year full-device warranty. Keep your proof of purchase with the user manual.

Real-World Applications

Home backup during outages. Anker suggests the pair for powering a basement. With 4,096Wh on hand, you can keep essentials running longer before you need to recharge.

RV trips. Add hours between charges on the road, and recharge the C2000 Gen 2 from the grid or up to 800W of solar when you stop.

Outdoor adventures and passion projects. Run camp gear or workshop tools for longer days, within the C2000 Gen 2's 2,400W output.

Practical Comparison

Expansion Battery Versus a Second Power Station

A second power station gives you a separate unit with its own outlets and its own charging. The expansion battery adds capacity to the C2000 Gen 2 you already own, so you keep one set of outlets and one set of controls while doubling stored energy.

C2000 Gen 2 Alone Versus With the Expansion Battery

On its own, the C2000 Gen 2 holds 2,048Wh and weighs 41.7 lb (18.9 kg). With the expansion battery, you get 4,096Wh, and the battery adds 15.3 kg as a separate piece you can leave at home or bring along.
