im sorry I made a post earlier talking about the problem I have. When set at 200 watts, 150 watts, even 100 watts and when I fire it (lets say when I have it set to 200w) the wattage instantly drops to 100 and then again it instantaneously drops to a wattage where the mod doesn't even seem like it's firing. typically I would see this as a low battery issue but on my screen the battery bar is full if not almost full. I just don't understand, I have been told I could adjust the Wh and that may help but I don't know! the battery may be junk but I never let it get below 3.6v, at least in my hands.
