Expandable capacity

Convenient reloading

Charging from solar panels, AC outlets, electric vehicle charging stations or our smart generator is easy. Plug the extra battery into DELTA Pro and they will charge and discharge in tandem.

More watt hours at home

The additional battery can be integrated into your home's wiring when connected to DELTA Pro. These battery units are part of your home's peak-shaving and backup power solutions.

Ready for emergencies

This extra battery can be charged directly from EcoFlow's smart generator outside, giving you another option for emergencies.

LCD screen

You get all the same information about battery percentage, remaining charge time, remaining hours and more on the built-in display. You can check the battery status anywhere from the EcoFlow app.

Make it a triple.

Double or triple the capacity of your DELTA Pro to 7.2 kWh or 10.8 kWh.

The DELTA Pro Smart Extra Battery takes advantage of all of the DELTA Pro's charging methods, including MultiCharge 6500W. This means you can charge anytime, anywhere as long as your extra battery is connected to DELTA Pro. Once connected, they will charge/discharge in unison, maintaining the percentage level of the battery on both units.

Ready for any emergency.

When the going gets tough and you run out of charging options, get a quick 1800W DC charge with the EcoFlowSmart generator (sold separately). Just plug the generator directly into your extra battery via the port on the back.

The smart extra battery has a bright LCD display on the front of the device that gives you all the information you need. Output, input, remaining charge and time left. It's all there. Need information on the go? The EcoFlow app can tell you all that and more.
