EcoFlow DELTA Pro 3 Smart Extra Battery
Product Description
We don't have verified capacity or weight figures for this DELTA Pro 3 Smart Extra Battery in the data we work from. What the name tells us: it's the matched expansion battery for the DELTA Pro 3 station, adding stored energy without a second display, inverter or set of AC ports. It's built for people already running a DELTA Pro 3 setup who need more runtime than the station alone provides. Call us at (619) 238-0205 if you need the exact Wh rating before ordering.

What it fits
This pack is built specifically for the DELTA Pro 3 power station. It isn't interchangeable with the extra batteries EcoFlow sells for the smaller DELTA 3 Series or the DELTA 3 Max Plus — those are separate products with their own connectors and packs.
What extra capacity buys you
Because we don't have a verified capacity figure for this unit, we can't do exact maths on the extra hours it adds. In practice, a matched extra battery for a DELTA Pro-class station is for people already running a whole-home or heavy-load setup who are hitting the end of the station's own charge before an outage does — not a small top-up for occasional camping use. Call us at (619) 238-0205 for the specific numbers on your setup.
Common questions about this product
We don't have a verified Wh figure for this battery in our data, so we can't quote you an exact number here. Call us at (619) 238-0205 and we'll track down the specific rating for you before you order anything.
The EcoFlow DELTA Pro 3 only. It's a different, dedicated battery from the ones built for the smaller DELTA 3 Series or the DELTA 3 Max Plus, and it won't pair with those stations even though they share a family name.
No. Every EcoFlow DELTA Pro-class battery is well over the 100 Wh limit airlines allow in carry-on or checked baggage, even without an exact figure to quote for this specific one. It needs to travel by ground or freight, not in your luggage.
No. It's designed to connect to the DELTA Pro 3 itself through a battery cable, not your home's wiring. If your DELTA Pro 3 is also wired into a transfer switch or home panel for whole-home backup, that part of the installation is a separate job for a licensed electrician — but the battery itself is not.
Adding stored energy at the station shouldn't change how a transfer switch or home panel is wired in, since the extra battery connects to the DELTA Pro 3 itself rather than to your home's circuits. Call us at (619) 238-0205 to confirm before you buy if you already have a whole-home setup installed.
If you already own a DELTA Pro 3, yes — you add stored energy without paying for a second inverter, display and case. If you need power output in two separate places at once, you need a second station, since this battery only stores energy for the one it's paired to.
