Diamond board, haven't changed anything on it at all. I guess I will try to get in contact with them about it but for now I will just keep the batteries out of the saber when I am not using it.
It is best to contact Ultrasabers. They are the professionals! I'm just a fan with some experience. Like 30 sabers and it has only happened to me once. Sorry it happened to you. At least when you send it back you don't have to ship the blade too. Just the hilt. Still sucks though. Enjoy your saber before the temporary separation. I already feel your pain.
