A Beginner that Needs Help

[EthanO]

I recently purchased a rda and regulated mod and I’m needed a couple questions answered. First if I’m running a dual coil build at .12 ohms, would that be okay with my mod? (Owners manual says mod is rated for 0.08-5.0 with the recommended being 0.3). Also would it affect my batteries?? I know with mech mods you would build based on the battery, so would that matter with regulated mods? I’m willing to listen to any of your help.

Your users manual will tell you the lowest coil resistance that you can use with your specific regulated mod.

Regulated mods and mechanical mods work a bit differently concerning resistance and batteries. A mech mod is totally dependent upon the battery's amp rating and the coil resistance = Ohm's Law.

Explain it to the Dumb Noob: Ohm's Law Calculations for a Mechanical Mod

Ohm's Law Explained for Vapers​

With a regulated mod, coil resistance is irrelevant. The power supplied to the coil comes directly from the circuit board, not the battery. Regulated mods usually have "boost circuitry" to increase the battery power and "buck circuitry" to decrease battery power. However, the amp rating of the battery to the circuit board is still relevant. The battery must have the necessary amps to the circuit board to deliver the desired wattage setting. Watts law applies here.



* Note that the amp rating of the battery determines the highest wattage the battery can deliver:

WATTAGE PER SINGLE BATTERY on REGULATED MOD:
(Total wattage doubles using 2 batteries; Triples using 3 batteries.)

It requires more power (amps) to drive a lower resistance coil than it does a higher resistance coil. So yes, the coil resistance (mechanical mod) or wattage setting (regulated mod) plays a part in how quickly your battery will be drained.

If you are using a single battery 60 watt regulated mod and you ask it to deliver 60 watts, then your battery will drain quite quickly. However, if you ask it to deliver only 30 watts, your battery will last much longer on a charge.

When using factory-made, drop-in coil heads for clearomizer tanks, the manufacturer gives "recommended wattage" ranges, usually written directly on the coil head.

Also, as you say you'll be using a dual coil RDA, keep in mind that using dual coils halves the resistance. For example, two 1.0 ohm coils will have a total resistance of 0.5 ohm, not 2.0 ohm. Your regulated mod's ohm reader will read the total resistance of the two coils as 0.5 ohm.

@Baditude ‘s description is correct. I’m going to try and simplify it a little. The result may not be quite as accurate though.

For really low ohms you need to run really high watts, and really high watts often need really high drain batteries. It’s dependent on what particular mod you have though to some degree so without that info it’s hard.

If your build isn't ok with your mod your mod won't fire the coil.

Depends on the mod. Some will just blindly do it anyway, some won’t. Generally higher end VV mods are the ones that will behave this way. It depends on what protections are implemented, how they are implemented, and if they actually function(which they usually do). It’s not a hard and fast rule though.

One thing almost no mods pay attention to is haw they drain the battery. The result is if you pull harder on a battery than it can comfortably give, you get an inaccurate wattage and a damaged battery, and damaged batteries can be bad. This is why people are so worried about counterfeit batteries. They have inaccurate claims about maximum draw, capacity, and wear rate.

I think his second question might refer to his coil assembly not having the recommended ohms. I'm thinking he's worried about his build being just a little "too" close to the minimum.

It's hard to decipher the post as it's consisted of such a small amount of information.

Yeah. The lack of complete information is a real problem. We’re having to guess at what he is talking about.

 

[EthanO]

You would be correct, I get that lower ohm builds require higher wattage. I’m just wondering if building that close to the minimum would affect anything battery or mod wise.

 

[EthanO]

Sorry for the confusion, this is all new to me

Depending on your mod, probably no. But we don’t know what the mod actually is so it’s hard to say for sure. Some mods have weird limitations. Electronics is complicated. Batteries though more likely yes. It’s about draw capacity. A battery’s rated draw capacity is what you can draw from it safely. They will frequently allow more, just not safely. Running a low draw capacity battery at a high draw can mean you damage the battery and cause it tow wear faster and possibly not actually give you the wattage you think you are getting as well. Again, there’s still no mod information, no wattage information, and no battery information so all that can be discussed is generalities

No worries. It’s new to everyone at first.

Now i'm thinking it's a mod with a built in battery.

The answers you need are completely dependant on the batteries you have, and whether they're old or new.

Sorry that I didn’t give the info, I’m just trying to not be one of those people that vents a battery. Everything is brand new

Bomber – not to single your comment out, but there is no connection between resistance and power in the context of a regulated device. I currently have in front of me 2 atomizers, one at 0.13 ohms and the other at 0.53 ohm. Which is set at the higher power? Removing any variances between airflow and juice saturation I could even tell you how much power is needed to raise each of these coils temperature by a given amount and offer an accurate time frame (ramp up)

Another way to view this is, say you have a Kanthal coil (can be any metal) of 24awg, 7 wraps around a 3mm ID. What does removing a wrap do to the overall resistance and mass of the coil and how is that effected by power?

On the flip side we also have coils running in Parallel which physically doubles the mass and electrically halves the resistance. This would require more power. But same coils in a series config would also double the mass but double the resistance. Again requiring the same additional power. Clapton type coils are essentially a Parallel circuit.

It's all about the temps the batteries reach. Pulling a lot of amps makes heat. If they're not getting too hot to hold, you're okay.

What are the maximum watts that can be used with a dual battery mod using two new "LG HG2" batteries with a dual coil dripper that ohm's in at 0.12 ?.

What are the maximum watts that can be used with a dual battery mod using two new "LG HG2" batteries with a dual coil dripper that ohm's in at 0.12 ?.

The coil resistance is irrelevant. 2x HG2 can safely offer up to 120 watts.

In a regulated device the batteries do not see the coil resistance like in a mechanical mod. So as long as you are within the limitations of the device the load on the battery does not change should you be using a 0.1 ohm coil or a 1 ohm coil at the same power.

So I should be fine correct?
