Whoa...black stuff not cool. Jay has his number listed on his website, maybe you should give him a call. I've found it's the best way to get in contact with them.
Just leave it alone and talk to jay,it looks like the head is blown.Like when you stack unprotected batts.I ordered my first batts from china and they said they were protected and apparently they were not.They blew the head.I had no idea,but when Jay got it he said the batts were probably NOT protected.Just send it in and let him see it.He can get you fixed up Im sure.
Are you using the same batteries that GLV sells?
