It can be used as a safety circuit for the 18650 used in various devices. If you incorporate the 18650 with this circuit in a light that uses 3 AAA beams, you can make a light that does not need to buy batteries.

They arrived quickly, it was what I ordered, I just need to put them in the rechargeable batteries, I recommend them.
