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.

Every Cell is Pre-Fused.

You need a save battery just in case something bad happens. 

The PwrBox Kits comes with 2a fused on both sides of each cell. 

Video Tutorials to help you get started.

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