Ok, First is it a single or dual battery Able?
how many batteries in the VW?
Now you might want to take a visit to
Ohms Law Calculator to see what's going on. Since you gave a fairly Vague specs, I'll start to explain a bit.
Let's say you have a single battery Able, and a .25 ohm build. Lithium Ion batteries when first charged run at 4.2 volts. If I plug in .25 ohms and 4.2 volts into ohms law calculator you SHOULD be running at 70.8 watts, and using 16.8 amps.. which is close to your battery's maximum. Now those are perfect conditions, and mechanicals are never perfect. There is always some voltage loss in mechanicals, so you're loosing some power depending on the mod you have. Also, as the batteries drain, the voltage of the battery will go down as you vape. The 4.2 volts usually doesn't last very long. Let's say after a few drags, you're running at 4 volts. now you're running at 64 watts.... which is about equal to your VW device. After a few minutes of vaping, your battery goes down to 3.75 volts.. which they usually semi-plateu for a while at... then you're running at 56 watts for optimal, probably 50ish watts including voltage drop of the mod. You can check out how the LG HG2 battery performs over a certain time and see how fast the voltage goes down. Take a look at
Battery Bro's review, and look at their graph about halfway down, you'll see this:
As you can see, on the left, it starts at the standard 4.2 volts, but drops almost immediately down to 3.95 volts within like a minute or two of their 1 hour test. That's typical of Lithium Ion batteries. After that, it slowly starts to decline at a steady rate until it reaches it's recommended minimum charge of 3.35 volts about 53 minutes of their test. If you had your atomizer on, and you were at the minimum, you'd be at roughly 44.9 watts optimal, but probably more like 35-40ish watts realistically.
This is assuming the HG2 is your battery, and you have a single battery mod.
That is why nowadays, most people prefer regulated mods for every day use. It maintains a particular wattage for as long as it can. For 60 watts, I'd suggest getting a dual battery regulated mod for both consistency of the vape and battery life. I occasionally use mechanicals, but it's rare. Usually I use a dual battery Cuboid or a tri battery Releaux RX200.
I have been keeping an eye out and might someday get a
cloned dual battery Able mod, but I don't recommend that for most users. Dual battery mechanicals add some danger to the equation that most people should't be messing with. But if I used a .25 ohm build in that mod, I'd be vaping at 207.36 watts for starting, and about 180 watts towards the end of the battery cycle probably Figuring an extremely modest %10 voltage drop, It's still pretty high and something I usually vape at, and still well beyond the danger threshold.
