How do electronics know what battery percentage they have?
In: Technology
Most batteries have a different output (voltage) based on how full they are.
For example in a lipo battery (common hobby bats) a charged 1 cell battery will output 4.2 volts, and its “dead” when it reaches 3.0 volts. So around 3.6v would be 50% charged.
However you can overcharge and over discharge these batteries, but doing that may result in a bad time that usually involves fire and toxic smoke.
