I've just returned my enduro Li-ion battery after it stopped working. Having taken it out of the bag I discovered that the casing had cracked in a number of places. The battery is about 2 years old and has not been abused and never crashed or dropped, so I have no idea how it has failed. I wondered if this is what is to be expected from a battery after a couple of years use or whether there's a case to have it replaced. Anyone else had a similar experience?

I also can't seem to find the endureo Li-ion on their website. They only seem to have the elite and pro. Does anyone know if the enduro has been superceded with another battery?
