The EcoFlow DELTA Pro Smart Extra Battery expands the capacity of your DELTA Pro to provide even more reliable power.  When connected to a DELTA Pro, it doubles the total capacity to 7200Wh, and adding two extra batteries increases the system to an impressive 10.8kWh, making it ideal for extended off-grid use, home backup, or emergency preparedness.  Recharging is simple and flexible, with support for solar panels, AC outlets, EV charging stations, or the EcoFlow Smart Generator, allowing the Extra Battery and DELTA Pro to recharge and discharge together seamlessly.
 
For home use, the Extra Battery can also be integrated with your home’s wiring when paired with the DELTA Pro, helping support peak shaving and emergency backup power during outages.  A built-in LCD screen displays battery percentage, remaining recharge time, and estimated hours of power left, while the EcoFlow app lets you monitor battery status remotely.  The battery can also recharge directly from the EcoFlow Smart Generator outdoors, providing an additional backup option when needed.  Note: This product is designed exclusively for the EcoFlow DELTA Pro Portable Power Station and is only available for sale in the contiguous United States.
