EF ECOFLOWDelta 3 Series Smart Extra Battery, 1024Wh LiFePO4 Expansion Battery for Power Station Delta 2/Delta 3/Delta 3 Plus/Delta 3 1500

Easy Install, flawless operation. Doubled my Delta 3 capacity, stores my single 320w panel, and powers my refrigerator. Love my Ecoflow products!!!

The quickest way to double the capacity of the already well designed Delta 3 Plus is to add this extra battery to it. Its only takes seconds to do so. It is hassle free and works immediately. Its a simple plug and play. My app found the new device and link them together without me doing anything to it. After plugging it in, i charge both units to full 100% to calibrate both devices. I only have to do it once and it balance itself out. Now it is draining at perfect in-sync percentage. Another improve is the extra battery cable is not in the back. It is not as visible as the Delta 2 series. Another thing is the extra battery stack on top of main unit like a champ. Its is not moving a bit. It feel so stable and pleasing. Definitely a well thought desgin.

I wanted to double the capacity of my EcoFlow Delta 3 Plus and this extra battery was the perfect fit. The Delta 3 smart LiFePO4 extra battery adds an additional 1024Wh to my smart power station. EcoFlow makes everything work so seemlessly. It literally is as easy as 1, 2, 3. Unbox, plug it in, and turn on your power station. It is really that simple. The app automatically detects the additional battery. Having this added power allows me to keep my refrigerator operating for over 12 hours in power outages. I am very pleased with how well it fits and stacks right on top of my Delta 3 Plus, great design.

The EcoFlow DELTA 3 Smart Extra Battery has been a fantastic addition to our camping gear. With its extra 1024Wh capacity, it keeps our DELTA 3 Plus running longer, so we never worry about running out of power during our trips.One thing we love is how long-lasting it is. Thanks to its LFP battery, it can handle over 4000 charging cycles, which means it’ll be with us for many adventures to come.Setting it up was a breeze. We just connected it to our DELTA 3 Plus, and the EcoFlow app lets us easily check how it’s doing.Its compact design is a big plus, making it easy to pack and stack with our other gear. Knowing it comes with a 5-year warranty gives us extra peace of mind.All in all, the DELTA 3 Smart Extra Battery has made our camping adventures more enjoyable by providing reliable and extended power when we don’t want to bring our much bigger EcoFlow Delta Pro Ultra.

Works great

Purchased this to double the storage capacity of my Delta 3 Plus. Its sleek and pairs perfectly. I use the D3+ to power my entire work-from-office as well as on the road to power my camper and mobile office. Having twice the storage allows for much longer run time when solar isn't available. Having a quiet power source that can be run indoors and recharged by solar panels is superior to loud gas generators in virtually every way. In my view EcoFlow has nailed the sweet spot for power, affordability, and portability with the The Delta 3 Plus and Extra D3 Battery. Love it! 5 stars.

This is not a plus Battery. This has only 3000 cycles not 4000

Excellent product purchase and support
