EcoFlow DELTA Pro Extra Battery

Expand your power capacity and extend your off-grid runtime with the EcoFlow DELTA Pro Extra Battery. Designed exclusively for use with the DELTA Pro Portable Power Station, this add-on module connects seamlessly to double or even triple your available energy storage—ideal for longer adventures, extended outages, or high-demand professional use.

Key Features

Expandable Capacity
Each Extra Battery adds an additional 3600Wh of storage to your DELTA Pro system. Connect one for a total of 7200Wh, or connect two for up to 10.8kWh. This extended capacity allows you to operate off-grid for longer durations or run more power-intensive equipment with confidence.

Flexible Charging
The Extra Battery recharges in tandem with the DELTA Pro through any supported input:

• AC outlets

• Solar panels

• EV charging stations

• EcoFlow Smart Generator

There’s no need to manage each unit separately—just plug in and both units charge together efficiently.

Home Integration
When connected to the DELTA Pro and Smart Home Panel, this Extra Battery becomes part of your home energy system. Use it for peak shaving, backup power, or daily energy management to reduce grid dependence.

Emergency-Ready
In emergencies, the Extra Battery can be recharged directly via the EcoFlow Smart Generator, ensuring you have multiple options to stay powered even when other sources are unavailable.

The integrated screen shows real-time data including:
