Today I tested the flashlight with my bench power supply and the maximum current, even in turbo, was less than 5 mA. Then I put it under the microscope and saw this. Photos are not of the best quality, but you can clearly see a vaporized bonding wire.


Meanwhile Banggood customer support told me that the battery is empty and that I should test a fully charged battery. Do you think it makes sense to show them these pictures? IMHO they are not able to understand what they see in these pictures.
