>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.

From what I've heard, it is more economical to recycle the raw materials than to reuse small packs.

Reuse of vehicle sized packs seems to be pretty common, though. I'd guess that a DIY home backup could be built pretty easily from used vehicle batteries.

The dude has a warehouse/workshop to do this work and house the system. I’m super impressed by what he’s accomplished, don’t get me wrong; but, what he’s done just isn’t viable for 99.99999999999% of people.

Give me an array and battery system that can pull off the grid and/or array and power most of my home without me having to think a whole lot or pay a vendor thousands to install while making the total cost under $1000 and I’ll do it.

Until then, it just isn’t financially viable when my electricity costs are well under $70/month average across the year.

Recouping the costs for install of solar systems are estimated at 30-40 years as of 4 years ago when I researched it. I’m sorry, but that’s just not worth it for me and most others.

I enjoyed noticing that your percentage (1×10⁻¹³) was so precise that it excluded the man himself (he is 1 in 8×10⁹).

I don't want to detract from your point. I just wanted to appreciate the hyperbole.

It's April Fools, so you have to pay close attention today; glad you caught my hilarious joke.
