thanks folks rfranzk : your web link didn't open could you please put it again !! GreekPIC : your project is for big barts and I need to do small one becouse the batteries are small as you know. thanks

As you know, many devices uses battery packs. Regarding that i face allot of problems inside the battery packs and i solve it by replacing the defective batteries with new ones. The problem is when we solder them by the welder it will not be strong and it takes time to do it. Also the heat of the welding may affect the battery. Is there any project to design a spot welder for batteries ? I Appreciate any informayion about it. thanks.
