i'm one of 'newer' vapers. how come you don't seem to bother with coil resistance? is that irrelevant in a regulated? like, i have an Alien which tells me Amp, Volt, Ohms. going by your assessment when i'm using low Ohm coils (0.1--0.2) it can sometimes have really high Volt readings at anything over 48W. when using coils 0,3+ it leans on the Amps. i think thats the right way round anyway, though it could be Vots for the higher coils and Amps for the lower?!? either way, if i stick below 110W i'm safe?
another thing i have learned also is the difference between parallel and series set ups, gaining Volts on series and Amps on parallel.
https://www.reddit.com/r/electronic...ries_and_parallel_mods_regulated_devices_and/ might be worth you mentioning that?
edit: reason i'm concerned is with the Alien i have been sticking to its read outs and using them, but, i just upgraded to an iJoy Limitless Lux for better TC and the fancy-schmancy user curve Watt setting (also 26650 batterys!). The screen shows me the Volt draw but doesn't have the Amps
With a regulated mod, coil resistance does not effect the amp load on your batteries- only watts and input voltage do.
48W at 0.1 or 1 Ohm will draw the same from your batteries regulated. What you are seeing on screen is the output of the mod- not the input.
The amps will be higher or lower at the output stage depending on resistance, but will be exactly the same on your batteries at the input stage regardless of resistance.
To put out more watts, more voltage is needed to provide this. Your batteries can only output the voltage level they are at- the board then either bucks the voltage down, or boosts it to provide the volts needed for your chosen power setting.
As long as you are using at least 20A batteries, 110W is fine. The calculation would be your watts divided by the input voltage, and as voltage falls amp load increases in a regulated mod, opposite to a mech mod.
The calculation, assuming a cutoff of 3.1V per cell, would be- 110/6.2=17.74A. Add in say 90% efficiency, and you are at 19.71A.
The majority of high power regulated mods are in series, as with a high input voltage in say a triple 18650 configuration high power levels can be achieved safely. There are some parallel regulated mods, but these are mainly for boards like the DNA75 which requires the voltage of one cell to operate.
There are some exceptions to this, but the benefits of dual parallel are more apparent with a mech mod than regulated. Regulated mods that use two 18650's in parallel rarely go as high wattage wise as series mods, and the calculation used is the same- watts divided by input voltage.
The ultra high power, quad 18650 mods use a series-parallel wiring, so you have both the voltage of a series input, and the increase in available amps of parallel.
Don't worry about the mod not having an amp readout on screen, I think this is a good thing. Also remember it
isn't the volt draw, this is determined by the voltage of your batteries, it is the output voltage after the board has done its magic.
Amp readings on screen just lead to confusion for new vapers as they think it is the amp load on their batteries- it isn't, it is the output amps.
