I have two questions. Does anyone know the amp limit on this device, and can you use one 18650 battery in it if you only need it to put out less than 3.7 volts? I ask because, let's say you build a 1.0Ω coil and want to vape at 3.5 volts, would using a hybrid 2250mah 18650 provide you with longer battery life?
