I’ve got a few projects on the list which will be battery powered. I’m thinking of using 18650s just because of how ubiquitous they are, but I know there’s other options out there. Are they worth it?
- E-ink calendar
- Solder fume extractor
- Lora station
- Portable “trail camera”
- Home assistant remote controls Etc etc etc
Yes, they are still good to use. There are also a number of other sizes of cylindrical lithium ion cells available if an 18650 won’t fit.
