My question is — who gets to use the backup power when it’s most needed? I would want one of these, but I’m concerned that when I need the backup power, it won’t be there because the data center has drained the battery, or wants it for their own use during the same outage.

Is there a cutoff - like 50% of the battery is yours, 50% is mine? Who truly owns the battery? Me? Base Power? The data center. I tried looking at their website but I couldn’t find an answer.

There also appears to be a “membership fee” of $19 a month, which is stupid if they are going to sell electricity I’m storing. That’s double-dipping.
