A man named Glubux has managed to power his home for eight years using a thousand old laptop batteries. This project involved extensive manual labor, including disassembling the batteries, adjusting cells, and constructing a custom battery rack for efficiency. Although the project showcases creativity and sustainability, it raises concerns about safety, reliability, and practicality given that such a system could take hundreds of hours to build compared to commercially available options. Some commenters emphasize the dangers associated with using old batteries, suggesting that safer, more stable batteries like lithium iron phosphate (LFP) cells would be a preferable choice. Additionally, while the project is intriguing as a DIY endeavor, it underscores the advantages of efficient modern supply chains that provide reliable battery systems.
