>the solution came with rearranging and adjusting the cells to ensure the packs worked more efficiently.

>Glubux even began disassembling entire laptop batteries, removing individual cells and organizing them into custom racks. This task, which likely required a great deal of manual labor and technical knowledge, was key to making the system work effectively and sustainably.

This kind of thing is cool as a passion project, but it really just highlights how efficient the modern supply chain is. If you have the skills of a professional electrician, you too can spend hundreds of hours building a home battery system you could just buy for $20k, but is less reliable.

There HAS to be a way to automate this process and make it work at scale.

The problem is likely cost effectiveness compared to just replacing a whole group of cells, compared to one single cell. The unit economics of getting the remaining life from single used laptop battery are not very good. There's certainly lots of potential value for someone willing to do the work, if they can afford the opportunity cost, or if a business can source extremely dirt cheap cells and cheap high skilled labor.
