I have an X7 VV eGo style battery, I believe the X6 may be similar. The battery (in my X7 anyway..) can't be removed. Well, it can, but.. Anyway, it sounds to me like the 'fire' button is stuck down. The light doesn't turn off at all? Mine has a 8-10 second cutoff if one holds the button down. I would do as BrotherBob suggested and call the vendor where it was purchased.
