I have two ego twist batteries. One 650 and one 1100. I charged the 650 completely last night and put my evod on it to be ready in the morning. I made sure it was off. When I went to turn it on it was dead! WTH I just got these like 2 days ago. Is there something I'm doing wrong? Let me know, I'm new at all the ego stuff and am very disappointed with the lack of charge these things have even with being off all night.
