I was wandering if anyone has inspected the cells after using battery for some time? We have here one pack with black marks and i would like to figure out what’s causing it. Some suggested that its from arcing caused by bouncing cells but i cant still believe that they are bouncing, especially in flat orientation, bottom deck mount.
