low ohm means lower voltage... When its lower voltage mena ur battery last longer to produce better vape experience...
This is incorrect.
@Zaybeee was asking about building low sub-Ohm coils and mechanical (unregulated) devices. In a mechanical mod, the voltage supplied is what the battery has at its present charge state. A fully charged Li-ion battery supplies 4.2v. If we have a 0.50 Ohm coil, Ohm's Law tells us that our electrical circuit will have to carry 8.4 Amps, since Amps = Voltage / Resistance.
The lower the Ohms (resistance), the higher the Amps (discharge, or current). The higher the Amps, the faster the battery is drained and the higher the probability of a battery failure.
Decreasing the resistance to 0.20 Ohms means the circuit must carry about 21.0 Amps, which exceeds the safe recommended discharge rate of most batteries being used by vapers today. Exceeding the 20 Amp limit is inviting a battery failure.
Mechanical mods should only be used by experienced vapers who understand the dangers of accidentally causing electrical circuits to fail and know how to take steps to avoid such failures.
Neither the Pulse nor the Luxotic is a mechanical device. Both have circuitry that protects against rookie mistakes like building too low, over-discharging the battery or installing the battery upside down.
