EcoFlow Extra Battery Compatibility Matrix

Extra battery compatibility is a complex topic despite the fact that many extra batteries and solar generators share the same XT-150 connector. For the most part, extra batteries only work with their main unit:

• RIVER Pro Extra Battery to RIVER Pro solar generator
• WAVE Add-on Battery to WAVE air conditioner
• WAVE 2 Add-on Battery to WAVE heat pump
• DELTA Pro Extra Battery to DELTA Pro solar generator
• Power Kits Batteries to Power Kits Hub

When the DELTA 2 and the DELTA 2 Max were released, EcoFlow did something interesting with the extra battery situation, allowing some mixing and matching of extra batteries and solar generators. The DELTA Pro 3 can use both the DELTA Pro extra battery and the DELTA Pro 3 extra battery, though in practice mixing two different battery sizes causes sequential draining and filling of the different battery types. With the introduction of the DELTA 3 and DELTA 3 Plus, EcoFlow also added the ability to add the mighty DELTA Pro 3 Extra Battery for a whopping total 5 kilowatt hours of capacity with the solar generator and extra battery.

BLADE EB - an Interesting Surprise

There is this little surprise of an extra battery, the BLADE extra battery, which looks like a DELTA 2 that has no display, no USB ports and is weather resistant. There isn't much information about this other than a product page and a tutorial video (Youtube). It has an XT-150 port and a special PV input port (this might be the same port that is used on PowerStream - only folks on the other side of the puddle can get this) with adapters that allow you to power a BLADE base as well as charge it with the BLADE power supply. According to the video can also act as an extra battery to a DELTA 2 or use a DELTA 2 as an extra battery.

Can a solar generator become an extra battery to another solar generator?

One question that is often asked is whether you can plug two DELTA Pros together or a DELTA 2 to a DELTA Max with extra battery cables to get one to work as an extra battery to the other. The answer is a definitive

Only extra batteries, Smart Generators, or WAVEs can be connected to the extra battery ports. You cannot plug a solar generator into the extra battery port of another solar generator.

Note, there are ways to get two DELTA Pros to work together, but that is using a Double Voltage Hub with a Victron AutoTransformer or a Smart Home Panel in 120v mode... a discussion for a future article.

Bottom Line

Most extra batteries only work with the same-named solar generator or smart device, but there are just a few exceptions. Then there is this little surprise of an extra battery, the BLADE Smart Extra Battery, which looks like a DELTA 2 that has no display, no USB ports and is weather resistant.
