DOTMOD 24MM PROBLEM

[sanox]

Hello i use dotmod LITE 24MM WITH RDA dotmod SS i have get new coils
CleanBuilds Coils - 26 gauge alien
i have bulid them on my dotmod and put battery NCR18650B LI-ON so i take some puff 1 puff work after more time dont work i dont understand why so i quit the battery and he was hot..
can someone said me why ?

That Panasonic battery is low amperage. That Alien coil is low ohm (no idea what, did you actually measure it?). You are overdriving the battery. It is getting hot because it is not appropriate for this use. If you continue to use it there is a very high chance the battery will overheat and vent, perhaps explosively. For your own safety, remove that battery, put the mod down, and head over to the mech mod forum to learn how to operate a mech mod safely. You are not doing so.

I don't know enough about your set up to help but one thing I can say hot battery is NOT GOOD. I WOULD NOT use it! Wait until some one that knows will answer.

ok idk that i all use LG HG2 18650 20A/30A 3000mAh but i get new battery the Panasonic ..

You still need to check the resistance of that coil and make sure you're within the safe operating range of the battery you choose. Same is true of the HG2. The HG2 is rated at 18A by Mooch in testing. Here's a recommended battery list by him.

It sounds like you also need to understand the basics of Ohm's law and figuring out what is and is not safe for mech mod vaping. Here's a link to a calculator to help you out. Ohm's law | Steam Engine | free vaping calculators

My advice? Stop using a mech mod until you have a solid understanding on how to use it safely.

ok thankes for help my mech mod i get gift i usually i use SUBOX MINI and the OHM of the coil when i check on COIL MASTER is 0.15 OHM i get

DO NOT USE NCR BATTERIES IN MECHANICAL VAPING DEVICES
I think that battery in particular is rated at less than 10a...maybe 6.5a or so.
Replace that battery immediately. Be grateful it did not vent.

According to Mooch:

• 
  
  
  • I am setting a CDR of 4.9A for this cell. While operating any cell near its rated maximum current level causes damage to the cell, I would expect good cycle life from this cell at 4.9A continuous

 

[Eskie]

A 0.15 ohm coil will draw ~25A at a nominal 3.7V. You would need a battery capable of supplying that, which means a 30A rated battery, the highest you can find (see above for the only ones to be truly rated at 30A, not the manufacturers inflated claims, the HB 2,4,6 are the only ones to make that cut). Personally, I'd never run a mech with a 0.15 ohm coil and leave myself with so little headroom for safety.

Please read up on calculating stuff like power draw and resistance before messing around anymore.

When using a mechanical you must measure the resistance of the coil(s) to ensure the battery amp demand it creates is less than the battery's CDR.

At .15Ω you are drawing nearly 28 amps from the battery,
only the LG HB series would be semi safe at that amp demand.
The LGHG2 is not suitable for that amp demand.

The ncr18650b cell is only capable of 6ish amps, you got lucky that something bad didn't happen. The battery got hot because it was nearing at least a vent or possibly thermal runaway condition.

What you're doing is dangerous...
Until you fully understand battery saftey, proper battery selection & ohms law it would be wise to stop using the mechanical.

thanks guys i think i start to understand about of all this i was read 2 hours right now.

more one a question i can use Thr NCR18650B and HG2 on dripbox 160w ?
OR I NEED SAME BATTERY ON THE MOD ?

No, you cannot use them together. Always pair batteries of the same manufacturer and same series, 2 HG2s, the same ones always used and recharged together (phrase is "married" for sets of batteries). It is not good to use one Panasonic and one LG, especially as their ratings are so different.

 

[Topwater Elvis]

The NCR18650B really isn't suitable for vaping use.
It can be used in something that never draws over 5a. (flashlight)

Like @Eskie said, in multiple battery power devices always use matched / married sets, same brand, series/model, bought at the same time always charged & used together as a matched set.
The batteries should also have a sufficient CDR to safely support the power range you intend to use (regulated power device), or, when using a mechanical sufficient to safely support the resistance range you intend to use.

 

[Ben85]

You are shorting out that battery so stop using it.

Do you understand ohms law?

Your blessed it didn't work. Look at Mooch list posted all over ECF..

NCR18650B -- Bad battery for vaping -- Stop using it

Learn more about safe mech use, buy decent batteries, use appropriate coil builds for mech mods.

You need a true 30 amp battery for that. The ones you use are not suitable. Your only option is pretty much the LG hb2, hb4, or hb6. And even then you shouldn't be building that low. You need to learn ohms law and battery safety before using mechs. What you're doing is putting you, and possibly others, at risk.
