New to vaping and concerned about battery safety.

[Seann]

So I bought a new sigelei 150 tc mod with the smok tfv4 tank and have som questions about battery safety.

I started to read about ohms law and whatnot and got concerned/confused about everything. The mod hold 2 battery's which are (2) efest 3100 mAh imr 18650 3.7V LI-MN 20A. My basic question is if the mod is safe to run at any level in regards to the current batteries. Also if anyone wants to help explain the correspondence between watts and Volts that would be great. Also is it normal for my ohms to change on my factory coil?

You are good with that device and tank. It's regulated so just wattage up or down to your liking.

As far as Volts, Ohms, and resistance its like this:

The ohm is the resistance of the coil. The voltage is how much you are putting to the coil. These 2 together determine your wattage (power) the lower the resistance, the less voltage it takes to get more power.

It really comes into effect on an unregulated device. Make sure before you use an unregulated device you are an expert at it.

The amperage is the limit of your batteries. So in a mech mod for example if I am using a battery that has 20amps I wouldn't want to build so low that the amperage the coil is pulling is above what my battery can handle. That is how you cause the battery to vent.

In a regulated device, such as your Sig 150 TC, you don't have to worry about this because the chip has short protection and won't let you fire it if there is a problem.

Battery safety is very important so although you have nothing to worry about with the Sig I would recommend you learning as much as you can about Ohms law.

Thanks you so much for all the information it was very informative!

I have a problem with this part FV.

You don't need a hard short to over tax a battery, just turn up the watts you're asking for.
The mod has no knowledge of what quality cells you put in it. The amp and resistance restrictions are to protect the chip on the board and keep within component specs. It doesn't monitor battery health.
The mod will take the battery voltage and pull what it needs to produce the wattage requested.

If I put in a couple of 5A rated batteries and bang it at 140w, I'm gonna have a bad day.

Seann... those Efests are probably okay 20A cells, though I would prefer something with a known, high amp pulse rating for high power use.
And that damn TFV4 is possibly the most insane, power hungry tank on the market today.
Vape safe.

I see what youre saying and you're right do not use bad batteries. However, the chip has temperature sensing in it to keep it from firing to combat this.

That would only matter if it were taking the battery's temp, which it's not.
The over temp cutoff protects the board and that's a great help... but bad things happen pretty fast with an overtaxed battery, the cutoff wont prevent that.

That makes sense. Moral of the story is to use good batteries lol.

Kinda true but a Regulated device only accepts as much Amperage as the battery provide it will not fire at all If you push the amps beyond the batteries capabilities since you are right that the mod is not monitoring battery health it is only accepting what the battery can provide making it unlike a Mechanical in this sense

Okay guys I've read everything that was posted and now I'm slightly co corned again. If these batteries are not the best than could multiple people confirm a battery that would be completely safe in my device no matter how high I run it? Thanks in advance.

If you don't push the power over 120W, you're fine with the batteries @Jim_MDP mentioned. However, if you want to go up to 150W, you want to use the Sony VCT4 instead.

I would not use the Efest 3100mAh 20A. General rule of thumb with Efest is to take half of the amps rating and treat that as the actual amp rating. Then they're great batteries at that level, they just rate them too high like all chinese battery sellers. So with the 3100mAh it's 10A or so, which isn't enough.

I would go Sony VTC4, VTC3, or LG HB2 or HB6. Those are all very safe choices. The 25R can work well in situations like this but I don't recommend it to people who are newer at this since above 130W or so it's really over the continuous rating.
