Hey guys/girls, I have a puma 200W vaporstorm, the other day it seemed to only drain 1 of the batteries. I put some fully charged batteries in it and it did the same thing again. I ordered new batteries from fogstar fully charged them and not the mod wont power on. I put the batteries into another mod i have the voopoo drag and the fogstar batteries are fully charged no problems. the partially drained batteries power up the drag. Am I doing something wrong? Is my mod seen better days?
