You asked if the battery could go outdoors.
Our initial battery offering need to go indoors. We have a couple of units in the pipelline that can be stored outside. Depending on how our testing goes we hope to offer later this year. As you can imagine, a unit that goes outside needs to be much more secure to keep the weather and bugs out. So that can add to cost compared to an indoor unit. Typically you will put it in the garage.
I'll post a picture in a minute.
