D3 Ultra Plus
I just purchased and received the D3 Max Plus Smart Extra Battery to go with my D3 Ultra Plus and when I plug the connection cable in then power the unit on it turns off almost immediately. I bought this EB based off the compatibility chart from the Ecoflow website. In my app with the Ecoflow assistant Beta it is telling me that it is not compatible!
-I understand you're experiencing an issue with your DELTA 3 Max Plus Smart Extra Battery shutting off when connected to your DELTA 3 Ultra Plus. Let me clarify the compatibility based on the available information.
According to the product compatibility matrix, the **DELTA 3 Max Plus Smart Extra Battery cable is not compatible with the DELTA 3 Ultra Plus**. The DELTA 3 Max Plus is only compatible with its own series of extra batteries (Delta 3 Max Plus Extra Battery), Delta 2 Max Extra Battery, Delta 3 Extra Battery, and Delta Pro 3 Extra Battery, and some models require a smart generator adapter.
Additionally, the DELTA 3 Ultra Plus supports up to one extra battery, but the DELTA Max Extra Battery is not compatible with the Delta 3 Ultra Plus.
Since the DELTA 3 Max Plus Smart Extra Battery is not designed to work with the DELTA 3 Ultra Plus, the shutting off issue is likely due to this incompatibility. I recommend using an extra battery that is specifically compatible with your DELTA 3 Ultra Plus model.
