Use 12 volt batteries.. Direct welding needle is used as spot welder.. Electric spot welding mobile phone battery.. Is it feasible?.
If the electrode is in place, it may be ok
Brother, no, absolutely not, welding circuit board is a special electric iron, not what you go to Baidu search for electric iron welding, welding circuit board will know, I also study the electronic, have not heard of this welding battery can.
You need an inverter to raise the voltage to 220V and then solder the mobile phone battery with an electric iron
