Ok I'm new at vaping. I bought a sigelei box mod 150 watt (10-150w) battery capacity 7.4v-8.2v\0.10 - 3.0 ohm compatible. I'm using sigelei 18650 30amp high drain rechargeable lithium ion capacity of 2500mah & 3.7volts. My tank is a herakles sub-ohm bvc atomizer with a 0.6ohm 50-100w coil. I vape around 55w to 75w and 5.9voltsish. Have I made a mistake am I doing something wrong have I put myself at risk for injury??? Please need help thank you.
