DIY Dummy 18650 Magnetic Battery Charger Adapter
Most chargers (your EastShine is probably no different) read the voltage of the cells as current is applied. They internally graph the voltage rise of the cell, and determine when the cell is full by looking for a plateau in the voltage climb, and then a small dip in voltage when the battery is full (usually a very small amount like 5-10mV).
How to demagnetize the core of a current transformer
Which of the following conditions tends to demagnetize the core of a current transformer? I answered passing a dc current through the windings. My understanding is that DC will *magnetize* the core.
