Convenient recharging

Recharging from solar panels, AC outlets, EV charging stations, or our Smart Generator is easy. Plug the Extra Battery into DELTA Pro and they will recharge and discharge in tandem.

More watt-hours at home

The Extra Battery can be integrated to your home's wiring when connected to DELTA Pro. These battery units become part of your home's peak shaving and emergency power solutions.

Ready for emergencies

This Extra Battery can recharge directly from EcoFlow's Smart Generator outdoors, giving you another option for emergencies.

LCD screen

Get all the same info about battery percent, remaining recharge time, hours left, and more on the built-in screen. You can check the battery's status anywhere from the EcoFlow app.

Make it a triple.

Double or triple the capacity of your DELTA Pro to 7.2kWh or 10.8kWh. That'll give you days of power for your essential appliances.

Charge anytime, anywhere.

DELTA Pro's Smart Extra Battery benefits from all the charging methods DELTA Pro has, including 6500W MultiCharge. That means you can charge anytime, anywhere as long as your extra battery is connected to DELTA Pro. Once connected, they'll charge/discharge in unison, keeping the battery percent level across both units.

Ready for any emergency.

When the going gets tough and you're out of charge options, get a 1800W DC fast charge with EcoFlow Smart Generator (sold separately). Just plug the generator directly into your extra battery via the port on the back. This works even when disconnected from your DELTA Pro.

Stay informed.

The Smart Extra Battery sports a bright LCD screen on the front of the unit giving you all the info you need. Output, input, remaining charge and time remaining. It's all there. Need on-the-go info? The EcoFlow app can tell you all that & a whole lot more.
