When connected to an EcoFlow DELTA 2, the setup expands from 1024Wh to 2048Wh total capacity. The extra battery uses long-life LFP battery chemistry with a rated lifespan of 3000 cycles to 80% capacity, making it a durable power expansion option for customers who already own or are purchasing a DELTA 2 unit.
