Don't bother. Just get yourself a 6-cell pack.

You can remove that 7th cell and simply cover up the end w/ new heat-shrink. Just be aware you need to be really good at soldering, and have a powerfull enough iron to solder a new tab across the last two cells without ruining them...

I rebuild packs all the time and it's easy to do but only if you have a powerful enough soldering iron, at least 50W or ideally more as you can't keep it in contact with the cells for more than a few seconds or you overheat the internals and damage the cell. I use an 80W Weller WH3 iron for mine.

The simplest way is to remove the extra cell from the end first by cutting away the black heatshrink, then cutting the clear heatshrink away from the end cell, but don't cut it flush with the remaining cells and try and leave 4-5mm extra length on the heatshrink.

You now have two options now. If you have a high powered soldering iron remove the spare cell and the tags, then solder one of the tags across the ends. If you don't have a powerful enough iron, to prevent damage to the cells peel the tags from the extra cell but leave them attached to the others. Now bend the two tags across until they meet and solder them together, this way the heat is kept from the cells. Once joined flatten the tags against the end of the cells.

Now you can insulate the end of the cells with tape if you want, but it isn't necessary. Now use a hairdrier on the heatshrink that you left attached and the extra length should fold over the end of the cells to keep them in the heatshrink.
