EcoFlow DELTA Pro Smart Extra Battery Features

🔋 Core Features

• Expandable Capacity: Adds an extra 3600 Wh of usable energy to your DELTA Pro, letting you double (7.2 kWh) or triple (10.8 kWh) total storage by connecting up to two Smart Extra Batteries.

• LFP Battery Chemistry: Uses long-lasting LiFePO₄ cells that deliver excellent durability and safety.

• Long Cycle Life: Rated for up to 6,500 cycles to 50 % capacity and 3,500 cycles to 80 % capacity, meaning a ~10-year lifespan with daily use.

• Plug-and-Play Integration: Simply connect to your DELTA Pro — no complex setup required. The system automatically charges and discharges in unison with the main unit.

• Seamless Charging: Supports all DELTA Pro charging methods — AC wall outlets, solar panels, EV charging stations, Smart Generator, and more — so you can recharge wherever you are.

• Smart Monitoring: Built-in LCD screen shows battery percentage, input/output power, and time remaining; you can also monitor it via the EcoFlow app.

• Emergency Ready: Can be charged directly from the EcoFlow Smart Generator even when not connected to the DELTA Pro — useful in power outages.

• Home Integration Support: When paired with DELTA Pro and compatible hardware (like Smart Home Panels), it becomes part of peak-shaving, home backup, and continuous power management systems.
