Anker SOLIX BP2000 Expansion Battery Gen 2 for C2000 Gen 2 - 2,048Wh with 10-Year Lifespan

Double your Anker SOLIX C2000 Gen 2 capacity to 4,096Wh with a single expansion battery connection:

The Anker SOLIX BP2000 Expansion Battery Gen 2 is designed exclusively for use with the Anker SOLIX C2000 Gen 2 portable power station, doubling its total capacity from 2,048Wh to 4,096Wh via a single dedicated cable connection. Setup is straightforward - connect the included battery-to-host cable to the C2000 Gen 2's expansion port and the system recognises and integrates the additional capacity automatically. No configuration, no extra cables and no technical knowledge required.

LFP battery chemistry and InfiniPower technology built for a decade of daily use:

The BP2000 uses LFP (lithium iron phosphate) battery cells, a chemistry known for superior thermal stability, long-term safety and resistance to degradation compared with standard NMC lithium-ion alternatives. InfiniPower technology takes this further, ensuring the battery retains at least 80% of its original capacity after 4,000 full charge cycles - the equivalent of charging and discharging the unit every single day for up to 10 years. For households using the C2000 Gen 2 as a regular home backup or daily off-grid power source, the BP2000 is built to last the distance without significant capacity loss.

4,096Wh of combined backup power for home outages, motorhomes and extended off-grid use in Ireland:

With the BP2000 connected, the combined system delivers 4,096Wh of usable capacity - enough to power a fridge for over two days, run essential lighting and device charging through a prolonged power outage, or support extended stays in a motorhome, campervan or off-grid property. The 9W idle power draw in Never Turn Off mode keeps the entire system in a ready state for instant deployment, making it a practical always-on home backup solution with minimal ongoing energy cost. For Irish households looking to extend their energy independence or prepare for grid interruptions, the expanded 4kWh system offers a serious level of coverage.

A 5-year full-device warranty that sets the BP2000 apart from the rest of the category:

Anker backs the BP2000 Expansion Battery Gen 2 with a 5-year full-device warranty - more than double the 2-year coverage that represents the industry standard across most power station and expansion battery products. This reflects the confidence Anker places in the InfiniPower technology and LFP cell quality at the core of the unit. For a product that is expected to deliver reliable backup power over a decade of use, the warranty provides genuine long-term peace of mind. A serious capacity upgrade for Anker SOLIX C2000 Gen 2 owners, available in Ireland today.
