Why use our PwrBox kits?

Build Large Packs FAST!!!

Building a 18650 battery by hand is very slow and very painful. Using the PwrBox kits you'll be able to make a 5 kwh Powerwall in less than 3 hours.

Video Tutorials to help you get started.

We have videos that shows you how to assemble each module and prepare it for final installation.
