I hook up my EGO battery to the charger when it blnks around 10 times while vapping. Now everything looks normal when I hook it to the wall charger, light on charger turns red and in a few hours the light on charger is green and the EGO light is also flashing ,is that normal? Now when I start vapping again it starts flashing 10 times again in about 10 min and does not heat up the atty of course. Any ideas?
