They put fuses on every single cell, another one between both halves of the setup, and monitor everything using a BMS. I wont claim that this thing is as safe as a commercially available product but treating this as if it where outrageously dangerous is misrepresenting things as well.
Comment on I Powered My House Using 500 Disposable vapes

That guy’s got some brass ones, lol.
I’ve upcycled disposable vape batteries for lots of projects, but never anything that draws significant amounts of current. Usually powering ESP8266/ESP32 projects that draw a couple hundred mAh.
I would be absolutely terrified to put that many questionable quality batteries into an array let alone try to draw any substantial amperage from them.

Yeah, I didn’t watch this video b/c I’m at work, but I have seen his ebike video so I’m assuming the construction is similar.
It’s just that all the fuses and BMSs can’t protect against a dodgy cell that decides to self-immolate. For cheap, disposable devices that are only meant to be charged 5-10 times or less and then thrown away, I’m super wary of the batteries that are chosen for those. Have seen too many things burst into flames and even expensive well cared-for devices turn into spicy pillows.

Good things to do, but it still only takes on poor quality cell to go up in flames and the rest will quickly follow.
Still very interesting.

I know almost nothing about electronics but this sounds really dangerous given how cheap these batteries are.

If powering fails, at least you could heat it!

If you’re not pulling 120v AC from a 3.4v parallel lipo bank, are you even living life to it’s fullest?

Europeans: Pathetic.

Ah, but can you phase-multiply 120v± into a 240v feed from the breaker? Checkmate, firestarter!
zout@fedia.io 1 year ago
I always wondered how that works? Do you have phases 180° against each other? Our (Europe) phases are at a 60° angle to each other, so while one phase is 230v, two phase is 400v.

At least I’ll heat my home!
