Unfortunately one of my batteries quit working last night. I have several unprotected 18650's that I ripped out of a laptop battery that unfortunately are going to have to suffice until I have some money to buy more.
I know the difference between the 2, I know the risks that unprotected batteries, but what should I look for before using such a battery?
