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
And you can get UPS battery boards for $3 USD often and in various output voltages. Definitely outsource your power supplies and battery managers.
