The EcoFlow DELTA 2 Max Smart Extra Battery is a 2048Wh LFP expansion battery that stacks onto a DELTA 2, DELTA Max or DELTA 2 Max power station. It is plug-and-play, adds capacity without a second inverter, and uses the EcoFlow app for monitoring. Its LFP cells are rated for 3000+ cycles to 80% capacity, roughly a decade of daily use, which is longer than the NMC packs in many older expansion batteries. It suits owners who already have a compatible DELTA and want longer runtime for outages or off-grid use rather than a whole new station.
