Don't know that I can concur for a few reasons.
1)VTC4's(Authentic) are almost non-existent leaving many purchasers with a re-wrapped 20a battery.
2) A .2 ohm coil is only as good and accurate as the builders capabilities.
3) Almost ALL cigalike explosions were Faulty Charging related, not actually through usage.
Not arguing the point, just pointing out the arguments.
