Powering an arduino 3.3V with a vape pen battery?

Has anyone looked if this is possible or crazy? The batteries are cheap and ubiquitous, and the connection is screw in. There's plenty on google about creating your own vape thing, but I'm interesting in using an existing vape battery.

Post a link to that battery.

Hes talking about 510 vape pen battery (this is battery, charger, and button/drive circuitry in one package), ubiquitous vape pen equipment.

I would be doubtful, because those batteries will generally detect an open circuit and turn off immediately, but a vape coil draws far more current, and the pen would see the very low current, and conclude that there was no coil or the coil was bad and turn off. Plus they have a timeout on them because continuously using a coil would damage the coil, so you could only power it for a few seconds at a time.

I have seen a fancypants box mod that had an adapter to charge a phone from, but it was specific to the mod - needed F/W support. That would work...

Use a power bank, or power it straight from a protected LiPO battery (straight into vcc (I use 3.3v pro mini, and the vcc pin on the ftdi connector so I cant accidentally plug it into serial port with battery connected, which could damage battery or computer), assuming it's based on a 328p which can run atop to 5.5 - if you remove the power led and regulator, you can get epic battery life with sleep that way, which isnt possible with either power bank or anything with a regulator)

The problem with most powerbanks is that, like vape batteries, they shut down if current being drawn drops below a certain value. They are mostly used to recharge phone batteries, and if they detect that the battery is fully charged, they shut down. That could be at 50mA. But here's one that features an "Always On" option:

Ahahhah, actually it sounds very interesting but also very crazy and it seems to me that it’s better not to do such experiments. I had an adapter that I bought for e-mail and I could connect the battery there and charge the battery using the phone. I decided not to pull out the battery and immediately connected the phone there and after five seconds my vape exploded in my hands. It seems to me that I have never experienced such intense fear ... Ohh, that was awful! It was sad because my vape and liquid were quite expensive. As a result, I had to buy a new vape and premium liquid from one of the most popular vapeshop and I spent a lot of money on it again ... In any case, it was a great lesson for me!

Are these 'vape batteries' the ones that explode ?

Only sometimes. :grinning:
