I understand you can discharge a battery completely with a resistor, just like any other capacitor. I also know there’s a battery controller in my device.
My actual question should’ve been ‘Do people really use lithium ion batteries in devices without battery managers?’ I absolutely would not.
- avar 1y agoNeywiny's comment upthread isn't that you should use these without a BMS, but that the review is relatively less useful because it's stopping testing at a relatively high voltage. E.g. if you search for "panasonic_ncr18650b.pdf" you'll find that Panasonic's own datasheets use a cutoff of 2.5v.
- Liftyee 1y agoSome do. Anecdotally, some (uncommon, enthusiast-grade) flashlights I use don't have battery managers/over discharge protection, though most of mine do. If you can bear the responsibility of maintaining and storing the batteries properly, IMO there's no significant problems.
