Description
The EcoFlow DELTA 2 Extra Battery (ZMR330EB) is the ultimate solution for users who need more runtime without the cost of a full second power station. By expanding your capacity to 2048Wh, you significantly increase the endurance of your setup; for example, it can keep a standard 120W refrigerator running for up to 28 hours or power a complete home office for several days during a "stima" outage. This makes it an essential investment for families and remote professionals facing frequent grid instability.
This extra battery is engineered for maximum safety and thermal stability. Using advanced LFP chemistry, it remains safe to use even in challenging environments and maintains 80% of its original capacity even after ten years of regular use. The connection is simple and secure: just plug the included cable into the expansion port of your DELTA 2, and the smart system will automatically recognize the extra battery and balance the energy levels across both units.
Efficiency is a core benefit of the ZMR330EB. Because it integrates directly into the DELTA 2 ecosystem, there is no need for extra power adapters or complex setups. Whether you are using solar panels to stay off-grid during a camping trip or keeping your critical medical equipment running through the night, the DELTA 2 Extra Battery provides clean, silent, and reliable energy. It is the smartest way to build a scalable, long-lasting power backup system that grows with your energy demands.
