Disconnecting / Dividing 4 Battery Parallel Pack to 2 x 2 Parallel Battery Packs

[xappys]

Hello, so as the title says I have disassembled 12 Battery Laptop Which is 11.1V so three 4 parallel battery packs connected in series to give out those 11.1V. I need info only for one of the three parallel packs.
So I need to divide 4 battery pack into 2 packs of 2 batteries in parallel. What I already did you can see in the photo of + terminals [I already cut point #1 of + terminals using wire clippers and tried to cut #3 of + terminals but as you can see it shorted with some sparkling and melted a bit of the metal]. I'm quite frustrated now, can you point out in what sequence shall I cut the terminals so I get the mentioned 2 x 2 parallel packs without shorting it out? Noob question indeed, but hope for your help . Thank you!

The entire can of the cell is negative, so when cutting the positive tabs you need to be very careful that the tabs (or pliers) do not touch any exposed part of the metal can (this would connect the positve tabs to the negative can so yield a short circuit).

Thank you very much! I understand what you said, as I can see a small hole in a plastic battery wrapping which was obviously creating a short. I guess the only way now will be to completely detach positive tabs of all 4 batteries and try to sand the tabs to get them soldered somehow.
