Why we picked this deal
Add 1024Wh to an EcoFlow DELTA 3 or DELTA 3 Plus for 110 dollars less
This stackable LFP extra battery plugs into an EcoFlow DELTA 3 or DELTA 3 Plus to add 1024Wh of capacity, and it's managed through the EcoFlow app. EcoFlow rates it for 4000 cycles to 80% capacity and backs it with a five-year warranty.
EcoFlow lists it at 389, down from 499, with no code needed. The catch: it's a pre-order that the page says ships in November, and a members-only variant is also shown.
