Less than a year after Tesla unveiled its Powerwall battery for storing electricity at home, a startup has designed a much cheaper alternative that you can plug in yourself, without an electrician.
The modular batteries, called Orison, can be hung on the wall or set on the ground to double as an LED lamp. If you want more power, you just add the units together.
“Think of Orison like Legos,” says co-founder and CEO Eric Clifton. “The 2.2 kilowatt-hour unit is really just one piece, so you can actually add as many as you need.” The 2.2 kilowatt-hour version is as large as the company could make one unit and keep it under 40 pounds, so it could be easily shipped and moved.
