Any ideas?
On the ground, near bus stops, parking lots, gas stations, anywhere people use them.
some head shops have return bins for recycling
Is there a particular reason that an 18650 or 21700 would suit your use case less?
Most that I’ve found have been on the ground near bus stops.
Is this for your Meshtastic board (from your other post)? If so, that’s a great up-cycle and should work well with the onboard charging.
I have a few I’ve saved for similar purpose, but I’m not sure about shipping them.
Like someone else said maybe check with vape shops / dispensaries in your area to see if they collect them for recycling.
Yes exactly that’s what I am trying to do. I just found a 3.7v battery in an ancient cellphone of mine, maybe that’ll work as well.
As long as it’ll still accept a charge and isn’t a spicy pillow, yeah, absolutely. I’ve never had great luck soldering onto those little pads but it’s certainly doable (though I’ll admit my soldering skills aren’t the greatest).
I’ve been wanting to play with Meshtastic for a while and was looking at using something like the LilyGo T-Deck with its blackberry-like keyboard to make cool little off-grid messengers for camping/hiking trips.
Honestly just get a heltec v3 from aliexpress, it’s only like 12€.
The board works with the cellphone battery, even with just holding the wires to the contacts ^^
