How can you do more damage to the pack with a spot welder?

In the case where you have to repair/service a pack. Solder is easy to undo, spot welds may damage/tear a hole in a cell.

The work around would be to spot weld to the cell, and solder to the bus bar.

It's easy to undo a spot welded pack. Cut the nikkel strips around the battery that need to be changed, then replace the battery. Then overlap the nikkel strips 2 row in X and Y Smile Done. Red = Nikkel strip and lightblue is the cut. 

1 min job. Soooo.... Smile But if you like solder better, that's the way you should do it. Offcause. Melt shit is fun!

The upshot of solder, it's easy to undo, in a case where you need to isolate a self discharging cell. The point I was trying to make in my other reply, but did not elaborate on. Once the initial joint has been done, soldering and desoldering is very easy, and can be done very quickly.

Also, melting shit is fun!
