I really like the Delta Pro extra battery but it has no inputs. How hard would it be to add some functionality and it would even look better? The battery comes as advertised. I would still recommend this extra battery to a friend because it is awesome. The charge rate is very fast (about two hours from one third charge). The price is right and quality is outstanding. It is super easy to use, my 8 year old grand daughter had it up and running in no time. Even my wife thinks this is cool. The product reviews just don't do it justice. I compared it to the other main players and they just did not add up. BLUETTI didn't even come close when compared to ECO FLOW DELTA PRO! I live in Albuquerque New Mexico and we have lots of sun here so I also bought two solar panels and that's the main way I keep these two bad boys charged (my ECO FLOW Delta Pros).
I would recommend this to a friend!

I bought the extra battery after I added a couple of 400 watt solar panels. It definitely charges, but no second fan which is a relief. It is important to update the firmware on the app for the latest algorithm as to how the two batteries discharge. It is a complex task deciding how much juice from the second battery when the first battery has a load. It seems like a lot of times it is about half. When charging that is the case and when running my microwave if definitely draws from both batteries. The percentage full display on each will never be the same and I recommend setting your delta pro with minimum and maximum charge settings (like 5%-90%). If the delta pro runs down to zero I don't know if the extra battery work in the most efficient manner.

I bought this on Christmas Day. It is performing perfectly.
I have only two complaints. While it is well known that the documentation for the Delta Pro and the Smart Panel are limited in details and usefulness. The Delta Pro battery has taken it one level lower by not providing any documentation at all. I guess it’s hard to find fault if it doesn’t exist. Sneaky.
I am also disappointed in the fact that an interface cable isn’t provided and it’s not recommended when you order the battery, even though the battery is useless without it.

I bought the extra battery to complement my Delta Pro and smart generator as a home backup system. I like the Ecoflow products and the way they provide the complete home backup solution. I do wish they would provide better instructions on connecting the extra battery and Delta Pro together. It seems there are some things that need to happen to get the BMS and cells calibrated. I had to go on facebook and describe my problem to gind out why my Delta Pro and extra battery were not discharging together. I haven't had the extra battery long but I believe I have a good backup solution and Ecoflow will correct any problems I may have waith their good customer service and the support of social media.

I have lived on boats and I am accustomed to using battery power and power management. When I saw what EcoFlow had produced with the Delta Pro I bought one, an extra battery and solar panels. I live in Florida and deal with power outages because of summer storms and hurricanes.
Now during a power outage I can sleep without the noise of a generator. Run the EcoFlow at night and charge by solar, assisted by my generator during the day.
I would recommend this to a friend!
