Power that scales with your needs

Meet the EF ECOFLOW Delta Pro Extra Battery, a modular extension designed to turn a single power station into a more capable energy source. When paired with the Delta Pro, capacity grows, giving you more room to run essential devices during outages, on camping trips, or in an RV. The setup prioritizes a practical blend of reliability and flexibility, so you can plan with confidence rather than uncertainty.

Expandable capacity for longer backup

With the extra battery, total capacity can grow from 3.6 kWh to 7.2 kWh. That expansion supports more energy for refrigerators, lights, routers, and small appliances when you need it most, helping you keep daily routines intact during power gaps.

  • Up to 7.2 kWh total energy when connected to Delta Pro
  • Potential for days of backup for essential appliances

Charge anytime, anywhere

The Delta Pro extra battery benefits from all charging methods supported by Delta Pro, including the 6500W MultiCharge. Connect and keep both units charged together; they charge and discharge in unison to maintain balance. In favorable conditions, you may reach a full charge in about 2.7 hours.

  • Multiple charging methods are supported by the system
  • When connected, both batteries stay at the same level for seamless operation

Ready for any emergency

For faster replenishment, you can use an 1800W DC fast charge with the EcoFlow Smart Generator. This works even if the Delta Pro is disconnected from external power, giving you a flexible backup option when options are limited.

  • 1800W DC fast charge via EcoFlow Smart Generator
  • Useful when traditional outlets or solar are unavailable

Stay informed

The extra battery features a bright LCD screen that shows output, input, remaining charge and time. Enhancing visibility, the EcoFlow app provides live data and insights on the go.

Smart control

From the EcoFlow app you can monitor and control the Delta Pro extra battery remotely, making it easier to plan outages or outdoor activities with confidence.
