Yes, they are.
It's ohm's law, not ohms loose guidelines.
It's the total resistance of the load that determines how much current will flow.

Ok so can I put my multimeter on my batteries to check resistance the same way I do for volts? And I figure that into the calculation of amps? I have 20 amp batteries and was thinking of upgrades. My coils are. 8 to 1.2 ohms in my tanks.

NO! 8-o
Doing so would be causing a dead short across the battery. Any decent meter will have a fuse that will blow to protect itself (& you) but don't tempt fate.
If you guys saw the full specs for the VTC 4 you'd poop.
30A is how they market them...they can do over 100A for a few seconds...lemme try and find that data sheet.
Pretty nuts eh? That's from Sony as well.

Can you say raw throat from vaping at that high of amps? I have vv/vw mods and batteries but never vape past the lowest setting call me a whimp or maybe I just like the flavor vs the the throat hit but I could never use a battery or mod at that high of a setting.
Good info. I was thinking it was a bad idea, but just had to ask!
So how do I find the resistance inside my batteries?

You mean put the meter on the atomizer to check the resistance of the coil?
You just switch the meter over to ohms setting first. And check the zero offset.
But using a regulated mod is alot easier; built in volt and ohm meter.
wow! that puts the internal resistance in the 10's of milliohm range!
One way is to buy from reputable batt. vendors, like Orbtronic, they'll have all those specs up!
It depends on your coils, wicking, and airflow; if you make your own thick wire coils and lots of cotton wick on a big deck your setup takes alot of power.
Fog machines take hundreds of watts; vape gear is really just mini fog machines.
You can calculate it from voltage drop; if you see a 10% voltage drop under load, then your internal resistance is 10% your load resistance.
Over-discharging a battery can kill it beyond an ability to recharge it, or worse cause it to go into thermal runaway. Battery meltdown mode. Venting extremely hot gas, expansion of the battery & possibly blocking off the mod's vent holes, turning the mod into a pipe bomb. Rare, but not so rare should it happen to you.

Battery protection and safety is so important, I think it must be made mandatory for people to understand it before they get into mechs.
That is one of the reasons I really like the VTC series, so much headroom, for those that are not careful and also for the unanticipated accidents.

All I see these days are ads for 30 or 35 amp batteries. And I ask myself, does the average vaper need this much amperage?
Plugging these figures into an ohm law calculator, we find when vaping at 1.8 ohms on a freshly charged battery at 4.20 volts, the current draw is only around 2.33 amps and less than 10 watts of power. And this current requirement (when using a mech mod) will only go down as the battery drains.
Obviously sub ohm resistances will require more, but even a .22 ohm build at 4.20 volts is only around 21 amps.
Any thoughts on this?
Indeed. However when the cloud chasers hit .0000000000000001 ohm they will need all the help they can get!
Holy CRAP, dude, you just solved all of our legal issues! We're not using e-cigarettes, just portable fog machines !!!
Not true*.
*depending on the battery. Sony VTC4's are designed to continuously discharge at a 30A rating. It has a separate pulse rating, generally given as around 60 Amps. This is because they are designed for applications requiring high discharge (tactical flashlights, laptop computers, and even UPS systems). I work with people who have designed tactical systems using 18650 batteries, it is amazing what you can power with enough of these bad boys.
