This add-on battery connects with a DELTA Pro to double total capacity to 7200Wh. Connect two of them to DELTA Pro for a staggering 10.8kWh to use off-grid. 

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.

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.

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

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.

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 longas 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 the acopylypse

    I bought one of these in May, right after Russia invaded Ukraine. I quickly realized I needed an extra battery, and now we have 2 generators and 2 additional batteries, will probably purchase 2 more batteries before the coming summer blackouts. Also have 10 220 volt solar panels and 4 160 volt panels in our back and front yards respectively. All of it works flawlessly, is idiot-proof and easy to install / move around. I get around in a wheelchair and I can handle these panels with ease. Highly recommended.

    Best Electric Generator Out There

    This is hands down the best electric generator available. The Ecoflow Delta Pro can power a refrigerator for 2 days or a high-end portable heater for almost 3 hours at a 1400 watt pull. There is no other electric generator on the market that will last that long. While it is heavy it is also very portable. We take it on camping trips, kids sporting events or anywhere outside where we need power. You will not be disappointed with this purchase.

    Used for one THING ONLY!

    This can't be used for anything else but to connect to the THE DELTA PRO ONLY. There is not one plug outlet or a USB connect. Its a waste!
