I have reconfigured a lipo in the past. Not by choice, but I was running a 2s2p and 3s2p 8000 mah packs for 5s total in my revo and I lawn darted a big jump and the gmaxx straps snapped(running them doubled up now). Anyway... long story short, I damaged one cell in each pack but did some very quick field surgery to remove the 1 damaged cell from each pack. When I got them home I was able to reconfigure the 8 remaining cells back into a single 4s2p pack. It was kind of a PITA to figure out what was what. The tabs all looked the same so after disassembling them(very carefully!) I went around with a volt meter and marked all of the tabs with a black or red mark (using a Sharpie) to indicate polarity and then reassembled it using solder and the connector board from the old 3s pack.

When I was doing this I was telling myself that I should take pictures, but didn't bother.

Anyway. Its not to bad if you know what you are doing eclectically. Just be very careful and pay close attention to how you are assembling. One false move shorting a cell will ruin it. If you do it just go very slow and pay attention to what you are doing.
