EcoFlow Extra Battery Flat Link Cable — DELTA Pro 3
This is the cable that connects a DELTA Pro 3 to its Smart Extra Battery, plugging into the rear port on each unit. The flat-profile design is the point: it lets the two units sit close together or stack without a thick round cable forcing a gap or getting pinched behind them.
Two lengths are available. The shorter 2.8ft (0.85m) version is for a battery sitting directly beside or beneath the power station; the 6.56ft (2m) version gives you room to separate them — useful when the battery goes in a cabinet, under a bench, or on a different shelf.

Choose Your Length
Measure the actual cable path rather than the straight-line distance — routing around a corner or up a shelf eats length quickly. If you're between the two, the 2m version gives you slack you can tidy away; call us at (303) 876-7654 if you'd like a second opinion on your layout.
Cable Specifications
This cable is specific to the DELTA Pro 3 generation. It is not the extra battery cable for the original DELTA Pro, the DELTA Max, or the DELTA Pro Ultra — each of those uses its own cable, which we also stock. EcoFlow doesn't publish a conductor gauge or current rating for this cable, so we haven't listed either rather than estimate them.
