EcoFlow DELTA 2 Smart Extra Battery


EcoFlow DELTA 2 Smart Extra Battery

  • Capacity boost: Adds 1,024 Wh of extra energy storage, effectively doubling the runtime of the base unit (from 1,024 Wh to ~2,048 Wh).

  • Battery chemistry & lifespan: Uses LiFePO₄ (LFP) cells, rated for ~3,000 full charge/discharge cycles before capacity drops to ~80%.

  • Seamless integration & “plug-and-play” setup: Designed to connect directly to the DELTA 2 via the dedicated extra-battery port. No complex wiring or configuration needed — once connected, charging and discharging are synchronized between main and extra battery.

  • Unified charging & discharging: Both units charge/discharge together — whether via AC, solar panels, car charger, or compatible generator.

  • Extended runtime for appliances/devices: With doubled capacity, you can run more devices for much longer — ideal for home backup, off-grid use, camping, or prolonged power outages.

  • Durable & long-lasting build: LFP battery + robust battery management system (BMS) ensures safety (over-voltage, overload, temperature, short-circuit protection, etc.) and longer usable lifespan.

  • Compact & stackable design: The extra battery is engineered to stack neatly with the main DELTA 2 unit (or other compatible EcoFlow modules), which helps save space and improves portability compared to carrying two full-sized stations.

✅ What It’s Good For / Use Cases

  • Extended power backup for home during long outages or load-shedding.

  • Longer runtime in off-grid settings — camping, RV, remote work sites, etc.

  • Running more demanding appliances for longer (fridges, fans, laptops, small power tools).

  • Solar-based setups: combining with solar panels to store larger amount of energy for overnight or cloudy-day use.

  • More efficient use — instead of buying a second full power station, you can just expand your current unit’s capacity.
