This battery has added so much more power and value to my Delta 3 Plus system. I can run my refrigerator AC Computer and microwave all at the same time with exceptional results

Awesome upgrade for my Ecoflow systems. Fast charging through all of my units, compatibility with the Delta 3 is great, lightweight, can move it around wherever I put the main unit with ease, and easy to get set up. An amazing value, especially with the summer sale!

Excited to finally have ordered the extra battery. I live in a microcamper full time and realized my power needs were more than I originally expected. The Delta 3 Plus was a great add on to save my vehicles battery, but needing to start the car to charge it was starting to use a lot of fuel. With the addition of this extra battery, the alternator charger (I recommend the 500w for most vehicles), and a solar panel, I'll never be without power again despite my gaming addiction. Just remember the Delta 3 Plus can only take one additional battery ^.^

I have this, along with the extra battery add-on acting as a UPS for my network server rack. I've had it for 3 months and it's been EXCELLENT! As a bonus, after I installed it, I discovered it can auto switch to supply the servers with battery power only based on my electric providers rate plan. I don't use any grid electricity now from 4-7pm when rates are highest. The performance has been so stellar, Im gearing up to purchase the EcoFlo home battery setup.

The EcoFlow Delta 3 battery works well with the EcoFlow Delta 2. What you may need to know is that: 1. You need to connect it to your EcoFlow Delta 2 or Delta 3 to charge it. 2. The cord that comes with the EcoFlow Delta 3 battery is not flexible, making it awkward to plug into the EcoFlow Delta 2 generator side charging port. 3. If you have the EcoFlow app on any of your devices, when your Delta 2 generator and Delta 3 battery plugged in and turned on, the Delta 3 battery will automatically be added to the app. 4. The EcoFlow Delta 3 battery will start to charge and if you press on the right facing arrow on the app beside the EcoFlow Delta 2 generator, you will see both the Generator and the Battery charging status and also, the length of time it will take to charge both. 5. Look at the front screen on your EcoFlow Delta 2 and look for the battery icon. This lets you know your Delta 3 battery is charging. If you don't see the battery icon on the screen, the battery is not charging. 6. The EcoFlow Delta 3 battery does not come with instructions. I had to look at a YouTub videos to figure all this out.

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.

Make sure you fully research your Delta 3 series power station if you plan to order more than one extra battery. Delta 3 1500 will only accept one extra battery.

Bought during prime days, good price. Fits perfectly with the delta 3 system. Glad they included the cable to link the two units together, 40 dollars if purchased separately. Effectively doubling the capacity. Test ran a full size refrigerator for 14 hrs with 10% charge left over
