As @Ryedan said, take a look at Mooch’s battery chart. I am adding a pic of that chart. I keep it on my phone Incase I’m talking to somebody at work that needs info on batteries. Here ya go!

I don't think I have a *full* knowledge of Ohm's law though the basic principles make sense to me. Were I to want to use a mech mod (I don't) I'd probably sit myself down with some really extensive reading material.

With that said, if a person wants to *push the limits* on their regulated mod, by vaping it at the highest wattage they think they can get away with, that person should equally be knowledgeable about Ohm's law, because if you overstress a regulated mod, equally bad things can happen (with perhaps less frequency, but bad things can still happen). In that case, the person should be familiar with Ohm's law and their battery tolerances. With that said, I do find, sometimes, that the person pushing the outer limit on their regulated mod is sometimes the person most LIKELY to not know about it. Maybe that's unfair to state, but most experienced users with a regulated mod, not looking to chuck the largest clouds possible, are often already familiar with vaping, battery safety, generally, etc.

I do think a new user who is starting with a sub0hm setup ought to be given a brief tutorial in Ohm's law, battery safety, etc., not just be told the device is the "latest and greatest" and can change the weather itself, leading to a desire to push the regulated mod far past battery capability and safety in some cases. I doubt whether that will happen, given B&M vendors tendency to sell *rewrapped* batteries without blinking an eye, but it would be nice if that sort of basic primer were given to a new vaper, even if it were in printed form, or something. Not everyone finds their way here, and I'd say there are probably a subset of vapers using their equipment unsafely, not really through their own fault.... That's a shame, though it is a user's responsibility, bottom line to educate themselves, no matter what. The calculations necessary for battery safety really aren't that hard, especially with Mooch's tutorials, etc.

But, I'd say that even though I generally understand Ohm's law, I do have a good handle on battery safety and as a MTL user on a Steampunk setup with safe batteries, I'd be truly shocked if anything ever blew up in my face.... I did learn a LOT about wraps on here, as well as charging safety, etc., and battery safety generally. IDK, maybe if makers of equipment also included some basic safety info (not just the standard, this equipment is for experienced users only statements that appear to be legal covering of butts) on Ohm's law and batteries.

I really think batteries are among the most dangerous things in vape. Not nic overload, not flavorings, but batteries.

With mech mods one needs to have ohms law and battery safety flowing out of their ears and nose. But nowadays so many people have regulated mods. The regulated mod makes up for a lot of the necessary knowledge for owning a mech because of all its safety features. Does that mean that for a regulated mod one needs to have just a basic all around knowledge of ohms law and battery safety or the same full knowledge like those who own a mech? Is a full and complete knowledge of ohms law & battery safety absolutely necessary for regulated mods? I'm not saying it's not necessary, just wondering to what extent.

Chips can fail.. it's always good to know factually that your vaping safe regardless of what your using, that way if some aspect of the safety features within the chipset in your mod fails, nothing bad is going to happen..

I'd rather have the knowledge and not need it, than need it and not have it.

I don't, and will never, trust every mod to tell me whether or not I'm within a safe wattage/voltage for the ohms I'm sticking on the batteries, every single time. I won't ever fly blind, and having no knowledge is just that - flying blind.

How Much Knowledge a person needs regarding Batteries/Electricity when using a Regulated Mod is debatable. I think Everyone should have a Good Understanding of How Things Work.

Here's a Good Example...

I have a Single Battery Regulated Mod that gives me Terrible Battery Life. I mean Bad. The 18650 Batteries I use are 3000mAh 20A CDR cells. Really Like the Mod. It's got a Nice Big Screen. Just Sucks Battery Life-wise.

Can I sacrifice some of the CDR Amps to gain some mAh and still maintain a Reasonable Level of Safety?

And if I went with a 3500mAh 10A 18650 to get Batter Battery Life, what would be the Maximum Watts I could set the Mod To?

I wonder where that extra power is going? Maybe the board in your mod is turning energy into low level heat or something.

I had the same thought myself about 10A batteries and read up about it last week. I found a Mooch post where he said that the top safe setting for a 10 amp battery was around 20W.

The Mod has a Big Screen as well as a Clock. And I would say that it's Efficiency Isn't the Greatest.

At 85% Efficiency and the Battery with a Voltage of 3.4 Volts, I think I could run up to about 25 Watts and still have some "Headroom" on the CDR. And I should be able to run 20 Watts with No Problems.

Knowing that I get my Maximum Battery Amp Draw at a Regulated Mod's Cut-Out Voltage (Opposite that at of a Mech Mod where the Battery has the Highest Voltage) is kind aligned with having a Good Working Knowledge of how a Regulated Mod Works.

And since I never run more than 20 Watts on the RTA's I use with this Regulated Mod, I could go with a Higher mAh 18650 with a 10A CDR.

It's extremely unlikely that a chipset would fail in a way that would transform it into an unregulated mod though. Simply calculating amp draw based on coil resistance and battery voltage is of little help unless that rather extraordinary circumstance would occur. More likely, a mod might fire at its maximum wattage ("watts law" calculation necessary), not have a functional low resistance protection (amp draw still calculated based on wattage setting), failed low discharge protection (measuring battery voltage necessary). Safety precautions are good, but the wrong precautions won't help much and might even provide a dangerous sense of false safety.

I second that;
Ohms law = not so much with regs
Battery safety = a good idea

I'd imagine the majority of ppl on this forum will/can/should have a varying degree of knowledge on both subjects.

Battery safety kinda like common sense though,
  • Don't stress it out
  • Don't allow it to complete a circuit of its own accord
  • Rewrap when needed
  • Chuck it if the cell is damaged
  • Charge it safely with a good charger

I believe vapers who use regulated mods wiith replacable batteries should be able to do a watts law calculation from memory and apply the result to their choice of battery and battery supplier.. Then they should watch some videos of batteries lighting up in people's pockets to understand why it's important. As far as mechs go, I'll stop vaping before I'll rely on them unless there is a kick and then they aren't mech's any more.

I've always used one brand of vaporizer. I buy the battery that was recommended by the manufacturer. When I restock my batteries, I go to a trusted source (now that the pv manufacturer is out of business) to get the same button top batteries that go with my PV.

I'm a cool vape type vaper. I dont build coils lower than 1.8. My preferred coil is 2.4. I set my watt to 5.4 or lower.

There is no danger in my vaping.

Battery safety is an absolute must. I have plastic cases that hold two batteries in a way that they cannot touch each other. Never use a battery that has a ripped or damaged wrapper. If you absolutely need to use that battery, use a piece of electrical tape to cover the spot. Replace the battery as soon as possible or re-wrap the battery as soon as possible.

Kayfun lite +

And a Kabuki that takes drop in coils. I get the 1.8 coils for that tank. The KFL I build to 2.2 - 2.4 range. Sometimes a little lower but never below 2.0. I find my battery lasts longer and I don't go through as much liquid. I still get lots of flavor and enough vapor to satisfy. ;)

Yup, you're good to go with that scenario Zoid :)

Steam Engine's battery drain calculator is good for these things. 20 watts at 3V from the battery will draw about 7.9A. I like to go a bit lower in battery voltage because of voltage sag under load. IMO if your batteries are coming out at around 3.4V after the mod stops they may well have been down to about 3V under load, or less if they are old.

BTW, I have one mod that gives me lousy battery life but the batts read around 3.6V when it stops if I remember correctly. In this case the issue is the mod is probably reasonably efficient, it's just not using all the power it could from the battery. That can also happen when batts are old and they have higher voltage drop under load but that was not the case here.

Also, the higher mAh batts generally have higher internal resistance so they have more voltage drop under load. That could mean not much more run time for you with the 10A batts. Running a 3000 mAh and a 3500 mAh battery through the Dumpfakkus website, seems to confirm this. Batt draw for that chart is 5A, the highest you can enter and voltage numbers are under load. If you would like to try some other combinations this is the URL.

Steam Engine's Battery Drain Calculator (as well as their Other calculators) is a Good Reference for Crunching Numbers. Or doing "What If's".

But as with just about all Data Entry Programs, it is Only as good as the Numbers that are Entered. And the Understanding of what these Numbers Mean/Represent in the Real World.

Which get's Back to Level of Knowledge Question the OP posed.

Because in the Scenario I presented, not Understanding things like when Battery Amp Draw is Higher at either Full Battery Charge or Lowest Battery, or Efficiency, or Internal Resistance or Voltage at Rest vs Voltage under Load, etc. can lead to Calculated Results that might not be Actually Occurring.

All that can lead to thinking you understand what's going on, when there might be something important that you aren't even aware of.

I don't worry too much. I use around 1.5 ohm coils at 10 W and treat my batteries well, so I reckon I have a good safety margin. But I could be wrong.

And I did have a Sigelei 20 mod that self destructed on me. Somehow it developed a short and killed a battery. I got lucky because it was sitting on the desk in front of me when it happened and I got the battery out just as it started to smoke. No amount of knowledge can help you if something like that happens. I went ahead and killed a second battery thinking that it might have been the battery rather than the mod. That part was kind of avoidable.

Knowledge you fully comprehend is power. "Thinking" you comprehend said knowledge is dangerous to yourself and others. I know my limits and have the sense to seek out the people who can help with what I don't get. I do believe people who don't quite get it can vape safely if they listen. You have to be willing to admit you don't know it all.
