When unexpected blackouts hit or your off-grid energy needs grow, the EcoFlow DELTA Pro Smart Extra Battery provides an effortless way to scale your storage. By plugging directly into the DELTA Pro portable power station using the included proprietary expansion cable, this unit adds an immediate 3,600Wh (3.6kWh) of reliable capacity. You can chain up to two Extra Batteries together with a single DELTA Pro unit to reach a massive 10.8kWh capacity, ensuring your home's heavy-duty appliances stay online for days.
Designed for complete integration, the Smart Extra Battery recharges and discharges in perfect tandem with your primary power station. Whether you are charging via rooftop solar panels, AC wall outlets, EV charging stations, or the EcoFlow Smart Generator, the connected units balance automatically. The clear front-facing LCD screen gives you real-time data on battery percentage, remaining charging time, and current input/output metrics. For remote management, the built-in Wi-Fi and Bluetooth connectivity link directly to the EcoFlow app, giving you complete oversight of your power network from anywhere.
Built to stand the test of time, this extra battery features a premium Lithium Iron Phosphate (LiFePO4) chemistry. It delivers an industry-leading lifespan of over 3,500 cycles before dipping to 80% capacity, giving you close to a decade of regular service. Safety remains paramount; the internal Advanced Battery Management System (BMS) continuously regulates voltage, current, and temperature in real time, defending the unit against overvoltages and temperature fluctuations while optimizing cell health.
