I got a 3.7V 2500mAh Lipo battery plugged into the Boron and when it chargers it makes a very high pitch whining sound. Is this normal?
Typically, this is not normal.
What could it be?
When I searched online, there are incidences where the battery makes a high pitched sound when charging. It looks like the issue should not be with the Boron but the battery itself, where internal components might have degraded.
