Your energy needs are growing and one extra battery is no longer enough? With the EcoFlow Smart Extra Battery Expansion Adapter, you connect two Smart Extra Batteries via a single cable, significantly expanding the capacity of your DELTA 3 Max Plus or DELTA 3 Ultra Plus.

The practical aspect: Instead of complicated wiring, everything runs through one cable. This saves time during setup, keeps the arrangement tidy, and reduces potential sources of error. This makes a real difference, especially with modular energy systems.

Instead of buying a completely new system, you simply build on what you already have. Ideal for longer off-grid trips, demanding consumers, or as a reliable backup solution at home. Are you planning long-term and want a system that grows with you? That's exactly what this adapter is made for.
