EcoFlow DELTA Pro Extra Battery Cable (2.5 ft)
This is the cable that joins a DELTA Pro to a DELTA Pro Smart Extra Battery, plugging into the dedicated extra battery port on the back of the unit. One cable per extra battery, and the DELTA Pro supports two.
It's easy to overlook when ordering a battery, and it's the one part without which the battery does nothing at all — so it's worth checking whether you already have one.
-
