Currently, I have glued a small element on one of the batteries that helps the batteries touch each other, so I don't have to worry about losing the magnet.
The batteries are made in such a way that they do not touch each other, so there must be aluminum or something else between them that conducts electricity
Hi, I recently bought a 1600mW laser from Sanwu Lasers but it doesn't work.
(I have 2x 18350 batteries) and unlocked with key
(It come without any watermark and warning sticker, i dont know if it's good or not)
