Save those old Laptop batteries!

Well here's a bloke (to use the Aussie vernacular) who's actually managed to make something useful and valuable out of old mainboards, wire, switches and a bunch of old lithium-ion battery packs from recycled laptops.

He's managed to cobble it all together to make a decent "Powerwall" with 40kwh capacity which is now powering quite a bit of his electrical needs, all out of his backyard, and he's publishing instructions on how to make your own.

"I needed something to get my ideas out of my skull and onto the bench, so to speak" said Pete Matthews.

Youtube

Now thats impressive!

Re: Save those old Laptop batteries!

I'd be concerned about reliability, spikes and surges but I guess he has protective circuits, or could just flip back to the grid if needed.
I'm also worried about fire as, depending where he lives, Australia can get very hot in summer and tin sheds are like an oven.

If this can compete with the Powerwall then it may save a lot of these batteries from going to landfill...
