People Are Using Old Laptop Batteries to Build Their Own Versions of Tesla’s Powerwall

Tesla’s Powerwall was intended to provide a convenient way for homeowners to store electricity for future use, such as when the power goes out. But with a $5,500 price tag, they haven’t been affordable for many consumers. 

Some who had been interested in the tech, however, decided to try to make their own: constructed their own powerwalls by utilizing old, recycled batteries from laptops. 18650 lithium-ion batteries are the most recommended batteries to use. They can be found in more than just laptops. DIY powerwall builders are recycling batteries and giving them a whole new purpose.
While companies like Tesla sell powerwalls, these DIY models allow people to save money — and potentially store more electricity.

WARNING: When building such powerwalls, you need to know for sure what you are doing (know the risks) because Li-Ion batteries are potentially dangerous when the cells go bad or they are not used correctly

    Build your own open source solar panels

    Do-it-yourself electricity generation is still difficult and expensive. The inventors of the SunZilla project aim to make it easier, cleaner, portable, quiet, and completely open source.

    The SunZilla system is designed to replace diesel and gasoline-powered generators for portable and emergency power: camping, events, mobile phone charging station, provide power to refugee camps, or keep the lights on during a power outage. Two people can set it up in a few minutes. It is modular and plug-and-play.

    Hacker Builds His Own Version of the Tesla Powerwall

    In 2015, Tesla announced their Powerwall power storage system. While the Powerwall didn’t generate the kind of excitement that Tesla cars have, the idea is actually very good. Essentially, it’s a huge battery pack designed for homes. If you rely heavily on solar power, it can store that electricity to get you through the night.

    Unfortunately, you just can’t get a new Powerwall right now, but you can follow Jehu Garcia’s lead and build your own.

    As you’d imagine, most of the money and labor for a project like this goes into the batteries themselves.

    The cheapest way to build a large rechargeable battery pack is to combine hundreds — or even thousands — of small 18650 lithium-ion batteries. Those can be purchased for less than $1 each

    The Quick-Build PowerWall
    https://hackaday.com/2018/08/11/the-quick-build-powerwall/

    Elon Musk isn’t just the greatest human being — he’s also a great inventor. He’s invented the reusable rocket, the electric car, and so much more. While those are fantastic achievements, Elon’s greatest invention is probably the PowerWall. The idea of a PowerWall is simple and has been around for years: just get a bunch of batteries and build a giant UPS for your house. Elon brought it to the forefront, though, and DIYers around the world are building their own. Thanks, Elon.

    Of course, while the idea of building your own PowerWall is simple, the devil is in the details. How are you going to buy all those batteries? How are you going to connect them together? How do you connect it to your fuse box? It’s a systems integration nightmare, made even more difficult by the fact that lithium cells can catch fire if you do something wrong. [jehugarcia] is building his own PowerWall, and he might have hit upon an interesting solution. He’s built a modular system to store and charge hundreds of 18650 cells. It looks great, and this might be the answer to anyone wanting to build their own PowerWall.
