The battery bar seems to flash when the wattage is at a certain point. If I'm using the crown with the .25 coil, the mod reads between .25 and .33 I've read that people have issues with the crown tank on the therion. The ohms will jump around. When I put the herakles plus tank on there with the .40 ohm coil it reads .41, the battery bar will blink if I run it anywhere above 65 watts.. Is the issue that two 18650 batteries have trouble pushing a certain amount of wattage for certain coils?
