EcoFlow DELTA 3 Smart Extra Battery 1024 Wh LiFePO4

The EcoFlow DELTA 3 Smart Extra Battery (EFDELTA3P-EB) expands the capacity of compatible EcoFlow power stations. It provides 1,024Wh of additional storage, extending runtime during power outages or off-grid trips. Built with LiFePO4 battery technology, the unit offers thermal stability and long-term durability. It must be connected to a primary EcoFlow power station to function, as it is not a standalone device. When paired, it provides the capacity needed to support high-wattage appliances for longer periods.

Weighing 9.6 kg, the battery is compact enough to be moved between locations. It charges directly via a connected EcoFlow power station or an EcoFlow Smart Generator. This integration allows the battery to recharge while the main station is in use, maintaining a consistent power flow across the system. The casing is built for durability during transit and storage, and users can scale their energy capacity by adding multiple units as required.

• 4,000 charging cycles — rated to maintain 80% capacity after years of daily use.
• 51.2V nominal voltage — ensures efficient energy transfer through dedicated expansion ports.
• Multi-unit compatibility — works with the DELTA 3, DELTA 3 Plus, DELTA 3 1500, and DELTA 2.
• 397.6 x 202 x 198 mm dimensions — compact footprint for easier storage in vehicles or cupboards.
• Smart management system — allows the primary power station to monitor and balance the extra battery's charge.
• Integrated on/off switch — provides manual control to activate or deactivate the expansion unit.
