ok, you are pushing higher wattages than I am so you're pulling more power from the battery, when they start running down it becomes more difficult for the batteries to supply the kind of power those coils need, this effect becomes more apparent as the batteries age. So I'm going to say that what you are experiencing is normal.Thanks, I use the T6 coil so running at 110w.
I might be wrong but it seem like the battery indicator is for 2500 battery. Will post a photo of the message it gives me when the vtc's is close to empty
