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
Yeah, I get you!
What I’ve done in the past is just buy a few charging boards with an integrated holder. USB/12v input, 3.3/5v regulated output. You can even get ones with solar. Then my circuitry can be independent of the power system.
And you can get UPS battery boards for $3 USD often and in various output voltages. Definitely outsource your power supplies and battery managers.
