Looks like awful lot of work to create such battery packs. I guess next step is to automate general assembly and dissasembly of battery packs via some smart AI robotics.

Try it manually first, can't automate a process if you don't know the process yet. That will prove the business case too, with a lot less upfront investment. The problem is that it doesn't scale; unless you have quality and reliability guarantees on the batteries, you won't be able to sell it in anything but unregulated markets, meaning that demand will always be low and investments in "smart AI robotics" will never…

You can sell the process, tooling, and support. Or, you can take a step back and wonder why it needs a capital solution and not a social one :).

Jesus. No cell balancing, protection or monitoring that I can see, and most importantly - wires directly soldered onto the battery instead of spot-welded. That's a fire hazard waiting to happen.

People, if y'all ever build your own battery pack, please think about safety. Or if you don't, place a giant bucket of dry sand above the pack, with the bottom layer being made of acrylic or other plastic that melts. That's about the only thing that can stop a battery fire.

I've been thinking about similar setups with lots of batteries as I have excess energy I can generate during the day and a lot of otherwise barely usable space in my attic. Fire hazard is my major concern. How do you make sure old (or even new) batteries don't do their usual thing, especially if they are in an environment with unstable temperatures and scarce monitoring?

Build a shed, or a bunker!

Honest question: is this a real hack that people do in these situations or did you just come up with it?

Why is soldering a fire hazard?

Just curious.

Why is this bottom layer important?

Presumably so that it melts in case of a fire, so that the sand falls down.
