PVA 18650 Resistance Capability Chart

Tinker Much Anyone?

“I did not forget the fans who love to build and fire a coil on analog”


Granted that many Vapers who started a few years back know their ohm’s law. We used a lot of mechanical mods because that was what’s available at the time. Although it may seem as if there isn’t much of a reason to go unregulated. There is still nothing smoother that using an analog signal. For this reason, I did not forget the fans who love to build and fire a coil on analog.

This time the chart is a little more advanced but still the same principal. Begin on your left to determine what is your battery configuration. This time series and parallel matters since our control is all based on the coil build. Then proceed to find your comfort zone. A triple parallel was omitted in this chart because of its unrealistic coil ramp up time.

Once again the math is done realistically according to Ohm’s Law. However, this time the high is calculated with 4.2 and the low is the nominal 3.6 the fact that once a battery comes under load, the voltage is dropped and therefore you will not start with anything greater than 4.2 volts. When fewer volts are applied to the same coil, fewer amps are used. When the battery is drained to nominal levels it could be ready for recharging as the voltage drop is still being applied from the load. Therefore using the mathematical range of 4.2 as the high to a low of 3.6 is more real world applicable of simulated use.

Please take note of the type E single battery range capping out at a recommended .14 – .12ohms. Does this mean my build of .08 on my mechanical tube cannot be fired even by a 30 amp battery? The realistic answer is no, and this is theoretically safe on normal use. Let’s define normal use: you are not firing the button down long enough for this setup to actually be dangerous.

Consider flooring it on a basic commuter vehicle. It is capable of 90 miles per hour, but how long must we put the pedal to the metal until this happens? How long are you firing your mech between draws? Therefore if the setup is not being drawn out to attempt the full duration of reaching max wattage settings. A few light taps on the gas is not potentially dangerous. So granted you must use a type E battery, building slightly over the recommended resistance setting is still safe because it is both inefficient and unrealistic. your setup is capable of over 100 watts on paper but holding it down for four seconds at single battery voltages will get you slightly half way to your calculation.
