Picture of my 2012 Zero XU battery is attached. Chaffing may be unlikely in my personal opinion. The cell pouches appeared to be packed too tight to allow chaffing and the pressure built up appeared to have warped the pouch cell cases. I had pouch rupture issue on 2012 Zero XU battery and 2012 Zero S battery. I still have that entire 2012 Zero S bike my possession and examined each pouch cell carefully for damage by taking the battery apart.
Here is what I observed. 50% of those cells were bad and and not recovered and the majority of these bad cells were ruptured and leaking. The other 50% of pouch cells that were not ruptured and not leaking were recovered. The 2012 Zero XU battery was damaged in a similar manner with ruptured leaking cells destroyed and good cell that I recovered. This are what I observed and documented with pictures.
I have enough recovered pouch cells to rebuild the 2012 Zero S battery and will be doing so shortly. I don't express any opinion as to what caused this this battery failure to happen as I am not qualified to do so.
