def looks like a handwritten 00:00:01 countdown clock on it lmfao

That thing in the back isn't a tablet, its 18,647 batteries in a metal trench coat.

Lol assuming this is an honest question, or answering for those that are truly wondering, 18650 is a type of battery, not the count. Like AA, AAA, etc.

Whoops https://www.circusscientist.com/upgrade-your-tablet-with-replaceable-batteries/

but replacing the battery doesn't mean you get to have a tablet with replaceable batteries

Context I live in a country with an unreliable postal service and shit currency. Also batteries were free from an old power bank

It is very unique for sure, I don't think I've ever seen this done on a tablet before!

I worry about being able to take the tablet outside the house without getting the bomb squad called on you, but I suppose you could maybe 3D print a cover for it, maybe even integrate a kickstand for that extra functionality lol

Free batteries from an old power bank...

Thank you that was the idea, In the missing tutorial I explain that I used batteries from a power bank with a broken usb. So yeah re-using stuff, this tablet should last 10 more years at least! https://www.circusscientist.com/upgrade-your-tablet-with-replaceable-batteries/

18650's? Those are a dime a dozen. Unless you want the actual company that made those specific ones. If that's the case, I can't help you.
