Get days of power for your essential appliances with the EcoFlow DELTA Pro Smart Extra Battery. This add-on battery connects with the EcoFlow DELTA Pro to double the total capacity to 7200Wh. Connect two of them to DELTA Pro for a staggering 10.8kWh to use off-grid.

The DELTA Pro 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 percentage level across both units.

Recharging from solar panels, AC outlets, EV charging stations, or the Smart Generator is easy. Plug the Extra Battery into DELTA Pro and they will recharge and discharge in tandem. The Extra Battery can be integrated into your home’s wiring when connected to the DELTA Pro. These battery units become part of your home’s peak shaving and emergency power solutions.

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 are all there for you to view. You can check the battery’s status anywhere from the EcoFlow app.
