5W led and 18650 battery
EN - the head flash light arrive as gift(thanks mate), and it was equipped with 3.7V 3.0A batteries which quite soon start to give up on “little” more use. So i decide to take my chances and broke apart one old Asus notebook battery. Inside was few bad cells but 4 at least was just fine. So, here it go. Little cut on top(the forehead of accumulator is same straight surface as the bottom) and adding little soldiering wire. Job done, and even work
