Agnius Mikutavicius posted an amazing video of his, uhm, durability testing of the A123 cells. He first shoots it with a shotgun and when that didn't do much besides punch a huge hole through the middle of it, he decides to ram an iron rod through the opening to try and short it out a bit. It smokes a bit and then he decides to put a hatchet through another new cell.
Watch it here:
I can't postage a thumbnail here since Agnius posted it as unlisted.
The results are amazing!
