Pretty decent price. This usually only happens with a combo deal. Main power station plus battery or battery alone. These will also work with the newly release delta 3 max models with an adaptor

this is almost too hard to pass up. Since I used my previous purchase of two D2M's, extra battery and solar equipment for my energy credit last year. can this be also used this year? I don't know if just batteries can be used that way

I had to pull the trigger I even joined Costco to do it , you can buy 1 on ecoflow for 750 for a while but I figured just finish it up with two.

You can. As long as they are "in service".

My understanding: you can easily charge ecoflow off a separate off-brand battery, but
  1. you need the right cable and
  2. you will have to charge the battery separately (need a charge controller or batt w/ one)
  3. however, you can get 5000wh for about 800 w a bit of patience
That's how ecoflow gets you: cheap "generators" with expensive add on batts (this is a nice deal though; certainly it's lovely to charge everything w/o moving cords around or having a separate charge controller.)
