Second Life Storage is one of those places that seems to belong to another era. In the era of Reddit and Discord, this is a forum, one dedicated to a single topic: batteries. One of its users is Glubux, and it has been sharing progress on a most curious DIY project for years: a house powered by more than 1,000 batteries. The key is that they are recycled laptop batteries.
And he has created a school.
Glubux Powerwall. On November 9, 2019, Glubux opened a forum entry in which he shared some photos and detailed his project: he had started collecting laptop batteries years ago, he had collected about 650 and was doing tests to check stability, performance and possibilities. Little by little he was sharing news such as the packs – cells – that he was creating with dozens of interconnected batteries with a great objective: to power the house with standard lithium batteries.
These cells are not created by chance: after dissecting each laptop battery, it classifies the units by capacity and rebuilds them into stable modules.

The idea was to create a large system that would work together like a conventional battery, but using those recycled ‘batteries’. He tried it and ended up connecting several packs to the home power. Less than a month later, Glubux commented that it had even successfully connected a vacuum cleaner for a total of 1,200 W of power and that there were no symptoms of heating. It was time to move on.

The shed. But of course, if batteries have taught us anything, it is that handling them is complicated and dangerous if something goes wrong. No matter how much care we take, something so homemade is likely to fail at some point, which could start a major fire. Having something like this inside the house is crazy, so Glubux created a very small shed on his plot, but enough to house the growing collection of more than 1,000 batteries.
Last year we already commented that the latest of their reports was that none had shown signs of deterioration (such as swelling) and, after eight years, they had not had to change any cells. Now, his house was running on solar panels that sent power to homemade recycled battery cells.

Feeding… everything. After expanding the solar installation (24 panels with 440 W), the storage capacity increased to 56 kWh and the system, which operates at 24 volts to feed A 3 kVA converter can power the house with its lights and appliances without problem. But it is not the only thing, since it also charges both a Tesla and an electric Nissan.
Creating school. Glubux hasn’t participated in his thread for a while, but that doesn’t mean he’s dead. Other users have been sharing their adventures when creating similar systems. Some were even more veteran and had more batteries, and the most interesting thing is that they have created a space in which advice is given about the cells, the capacity of each of the cells or how to join batteries so that the systems are stable.

Not so homemade. These projects are almost as exciting as finding yourself in 2026 a furo so rudimentary that it still has an active community, but it must be said that powering the house with a wall of conventional batteries is not so exotic. In fact, Panasonic recently said it was reaching the limit of its capacity to produce battery cells for data centers.
These are cells very similar to those of the Glubux project although, obviously, initially created to power systems such as data center racks. They are still systems made up of packs made up of hundreds of ‘batteries’. And now I can only wonder if Glubux’s silence is because it is building its own data center next to the shed.
