So I have a cell phone that is broken, but the battery is not. I saw this as a perfect oppurtunity to make my first mod. Making it work is easy, wire from battery to switch to atomizer and back to battery, but what about charging? The battery has 3 contact points. the two closest to the positive symbol will light up an LED just a little when i touch it to them, but if i put if i put the negative part of the LED to the one closer to the negative symbol it lights up a lot. so is one of them for charging? can i solder the charger ports wires to the positive one to the left and the one in the middle? Sorry this is hard to explain through text...
