Tesla’s Powerwall – A Convenient Way To Provide Home-Owners To Store Electricity

A convenient way to provide homeowners to store electricity was the general idea behind Tesla’s Powerwall. However, $5000 was a bit too much for most people.

There are of course those who dabble more than others, and interestingly enough, they started poking around and suddenly homemade powerwalls weren’t just affordable, but as well managed to get the close to storing as much as the original invention.

Utilizing old, recycled batteries from laptops provided the building blocks of the DIY powerwall. Although useless at first sight, DIYers managed to utilize them

There are a lot of videos flying around the internet which is dedicated to help people build their own powerwalls. One YouTuber, Joe Williams, explains that it all comes down to being able to trust something you built yourself — as opposed to what a company says is right for you.

“The end result is being able to rely on something I not only built myself but understand the ins and outs of to power some or all of my electricity in my home. That is inspiring,” said Williams to Motherboard.

Tesla’s Powerwall is capable of storing up to 14 kWh, but that’s not due to the limits in technology, since others have been able to store much more. On the DIYPowerwalls forums, one user named Glubux claims his custom made powerwall can hold up to 28 kWh.

Peter Matthews has managed to build a powerwall, which according to him, can store up to 40kWh (solar panels on his roof are the main electricity contributor)



18650 lithium-ion batteries are the most recommended batteries to use, and they’re easily identifiable by their colorful plastic. They can be found in more than just laptops, but collecting enough of them to create a powerwall can be time-consuming.

Foraging may be a more economical option, however, since store prices for batteries can be more than US$5 per battery.

Having less impact on one’s finances isn’t the only benefit to building your own powerwall. Since people often throw away their laptops without removing the batteries, they usually end up in a landfill. But DIY powerwall builders are recycling batteries and giving them a whole new purpose.

“Approximately 95 percent of consumer batteries sold in the US are not recycled and are ultimately thrown away,” said Call2Recycle CEO Carl E. Smith to Motherboard.

This is a simple proof of what people can do and shows that people are the ones who eventually make the worthwhile hardware thus showing companies that consumer prices for that specific segment are not good.

Of course, there are some risks to building a powerwall, but given the proper tools, enough time invested in doing research and of course ingenuity, can take

We advise that messing with old batteries can be dangerous, and we do not recommend anyone attempting to create their own powerwalls without first looking at the risks involved.
