My firing pin on my m16 was working perfect until recently the firing pin is somehow getting hot in running a .46 ohm dual coil with a nucleus clone RDA. I have cleaned all the connecting points top pin bottom firing pin I don't know why. I'm using a Panasonic 18650. Any ideas of what's going on?

If my button on any mech starts to get warm it is time for a polishing of all of the contact points within the button, not sure what your cleaning entailed but if just a soap & water scrub it needs more. A hour or two soak in ketchup will help get the oxidation off the threads too, can't polish that too well.
I use mothers metal polish that I have in the garage but just about any polish will work.

What type of Panasonic? Is is green with black marks on the top and bottom of the battery? You are pulling 8.9 amps from the battery. If you have the 3400Mah Green Panasonic, they are only rated for 5 amps. Check the battery, is it hot all the way from top to bottom? If so STOP, do not use that battery! Recycle it and get a new one.

The other possibility other than dirty contacts is that you have a short somewhere on the atty or on the 510 connector. Check the insulators on your atty and mod carefully.

Just the firing pin is getting warm it's at 3.91v . , .46 ohm it's a nucleus clone by Hcigar there is no jumping around on my ohm Meter. Ketchup I haven't heard of that is it the acid in the ketchup that cleans it? It helped since I've broke everything down but I do only use soap and water I noticed my firing pin was loose after I tightened it is when I got the problem. Both of these were bought from a local B&M that claimed they were completly safe. He showed me his 26650 mod he was using the same brand of battery. I do not want to endanger myself and cause it to blow. Where can I grab some good batteries if these are not safe. I only plan on being between .3 - .9 ohm I appreciate your all's help thanks!

That's like an efest on acid. Is that just the picture that's bad?
I'm not familiar with that Panasonic so maybe someone else can comment. I'm sure you can google it to find its max discharge amp rating though.

Sometimes pulling it apart will show you something that's not tight or just not going right inside the button. A good polish on all of the metal to metal contacts within the button works wonders.

Yeah, the acid helps clean brass and copper. I soak it for a while and scrub the threads with a tooth brush then soap & water. Helps clean them up for better conduction.

Yea the picture quality is bad where I had to resize it to put it on here. Still getting use to editing ha . The rda is getting hot but there is no short? I'm so lost on this. But I think I found something the coil itself was touching the negative end and was showing a short .could that possibly be what was wrong. I was using 28g I now have 26g coils in the with not much room to work with

That could very well be it, the coil shouldn't touch the attomizer anywhere. Only the legs coming off the coils into the posts.

If you are cramped, maybe try build a smaller diameter coil to fit better?

It looks like the deck is sunken below the side walls and that can be a little trickier to build on. On your next atty look for something that does not have tall sidewalls that block the coil building area or a removable ring (like a hobo) to let you get in there and build. CLT V2 is a good example if you look at a pic there is nothing to the side of the coils until you put the top cap on. I also like dual hole center positive post so that each wire has its own hole, no shared holes makes building easier.

So I had a 3hr dip in ketchup everything completley broken down scrubbed with a toothbrush made a new build @ .38 ohm built on a 5/64 screwdriver using a fresh charged battery . But now my batteries are getting a little warm im stumped.... not hot just warm to the touch. I also tried my tangsfire 18350 they are doing the same thing. I switched over to my k100 with a tank and All of my batteries are doing that I live vaping but want to vape safe. Maybe in being too cautious I read it will get warm ( not ouch to the touch) chain vaping (which I do) What type of batteries are you using FQ?

Batteries will get warm just from being in the mod with an atomizer that generates heat attached to it. That heat may not be so much from the battery but just from the mod getting warm.

My batteries get warm too (few degrees over ambient... not hot or anything) 0.5 ohms in an orchid is about as high as I get. Dripper gets a 0.3 build and gets the mod even warmer.

The 18500 efest... I wouldn't run that below a 0.5 ohm build to stay well within it capabilities. I wouldn't use any 18350 on a build below 0.7 ohm and that would be a high quality imr aw or purple 1830.

I run sony vtc5's, 4's are just as good if you can find them. Can't find the 5's anymore.
LG HE2's are also a really good battery. A buddy got a couple the same day I got my last vtc'5 and a few months later and they both have the same internal resistance. Seat of the pants performance between the two is also equal.

Kinda related... but not. Just something to know.
These 18650 batteries are all about the same size. When you see a 3000+ mah battery that's the same size as a 2000 mah battery and wonder... how did they do that?
The smaller capacity battery will have a higher discharge rate (power) than the one with a higher capacity (fuel in the tank) assuming both are high quality batteries.
Capacity takes space and high discharge capability takes up space. You cant fit both in there so you have to choose one or the other or a compromise between the two.

Do some digging in the battery section of this forum, some good info there. Orbtronics looks like they have a good deal on HE2's but i haven't bought from them before. See where people in those threads have bought from and got authentics to be safe.

I haven't really kept up on the new batteries because I don't need any right now but I have a feeling I will need to see what is the top performer pretty soon as I have 9+ months on a couple of sony's and one that's a couple months old. They don't last forever so I think I will be researching that soon myself.

Seems like the Samsung 25R and LG batteries are the big kids on the block now.

Orbtronic is a trusted vendor. They have a 30 amp battery available. Rewrapped vtc4. You can get them in flat or button top. I've bought LG HE2 20 amp'ers from them. No issues at all. They include plastic battery boxes in the packaging.

Cool, they have good prices so they may be where I order from. Which 30a are you talking about?

The orbtronic 30A. Not sure specific # off to my head

The sx30 2100mah. They also have decent prices on xtar chargers which are quality devices. A little more expensive than nitecore stuff, but better quality and worth the price in my humble opinion. The mp1s is a great single bay for only $10. I'd rather have two nice single's than one 2 bay. That way if one fails (unlikely with an xtar)....

I just bought a nitecore i2 2 days ago do you think it will be ok. I cannot find any info on my Panasonic cgr18650da if it's imr or not. I read people use them but I don't want to endanger myself. I'm thinking about buyinga few sx22 or sx30s later tonight

These? http://www.tasteyourjuice.com/wordpress/panasonic-cgr-18650-3-7v-2250mah/
If so they are only rated 10A...
That i2 will be fine I usually test a battery after its fully charged with multimeter to make sure it's not overcharging.
Also Purple Efest 30A 2100mah are VCT4s as well

I use a xtar mp1 as my main charger. Definitely recommend it

Quit using that Panasonic CGR18650DA for Subohming immediately. It does not have the discharge capacity for Subohming. It's a 2C battery max discharge! It's an accident waiting to happen.

Panasonic CGR18650DA
Nominal voltage: 3.70V
Maximum charge voltage: 4.20V
Minimum discharge voltage (cutoff): 3.00V
Continuous discharge rate: 1C (2.25A)
Burst discharge rate (60 secs max): 2C (4.500A)
Maximum charge rate: 0.5C (1.125A)

http://www.actec.dk/Panasonic/pdf/CGR18650D.pdf

Get Samsung's or LG's with a discharge of 30 amps.

These? I'm looking to go down to around .2 ohm I was looking at the sx30s.

The picture is a 20 amp LG. Good down to about .21 ohms. The sx30 can safely handle down to .14. Down that low, slight differences in resistance greatly affect power draw.

It's been inferred, but do not cheap out on your batteries. Buy the best you can, not the cheapest.
Don't buy janky-looking clones of batteries either. Many fakes are out there. If it looks like it's been printed by a 5yo or has misprints..flee.

I recently got two Samsung 25R batteries for $17 shipped and they can be found even cheaper. Worth it for my piece of mind.

You also need to know what you need for how you're vaping.
I still love the old Panny CGR18650CH grey batteries, but I wouldn't go below an Ohm or so build on them. ;-)


FWIW, here are two other sources I've bought good cells from:

I appreciate all of your guys input I've been doing alot of research on batteries it gets confusing at times. I have a chart that helps me out alot I got from here. I plan on going down to .1-.3 ohms but I personally like staying around .5 ohms. I'm at .8 ohm right now. I don't understand how people are doing those super sub ohm builds and not blowing themselves up.

Look for 25R rated batteries, batteries that can handle 30 amp draws. The Samsung are very good cells, I just bought 4 to replace some worn out Sony VTC4's I had.

Here's some good cells, buy a couple and ditch that CGR18650DA battery. Its only good for flashlights: http://101vape.com/batteries-charge...drain-flat-top-battery-pair.html#oid=1003_323

Efest advertises the pulse rating when the continuous discharge rating is what is important. They're being deceptive.

The 35a efest is a rewrapped lg he2 20amp battery. Efest lies.
So does every vendor selling those LG HE2s.... I ALWAYS see them marked as 35A.
Don't always believe what you read on the Internet. I run my supposed 4A efest well above 10A without issue and have for months.
It's frustrating that everyone has jumped on the bandwagon stemming from one post over on the ECF.
/rant
But in all seriousness, if you want to be safe stay within your batteries continous amp rating, accidental firings happen all the time. Yes pulse rating means you can go lower but only for seconds. Bad things can happen with an unlocked mod in the pocket ;).
My recommendations
Any of the Sony VCT series if you can find any legits
Efest 30A 2100mah or 35A (Really 20A continuous) 2500mah
LG He2 35A (really 20A Continuous) 2500mah
Or Samsung 25R 20A 2500mah

They are what I've been using in my mechs without issue

Use what you want. I just think it's good to know what the actual cell and ratings are. The sx30 is a great cell as it's a rewrapped vtc4.

I actually just ordered 2 sx30s! So stoked to get them! Looking into ordering a few actual vtc5s from obitronics also. I just want to be safe when I do finally build something at .1 ohm I like .4-.5 ohm it seems to bea good vape for me but have recently been building .7-.9 ohm to stay in the safe zone with my batteries. I haven't had any over heating problems at all since I've been staying between .7 and .9 ohm.

Vtc 5's have been out of stock for a while.
Lol I Just found that out ....I'm behind on times ( new to mech mods) haha. I just did order a DNA 30w box mod looking for a few good batteries specifically for it.

2014-11-29 17.12.57.jpg Finally got my Intellicharger i2 waiting on the couple of sx30s for my sentinal. Until then I'm using a .8 -1 ohm micro dual coil's in my mod to be on the safe side. Still deciding wether to get some efest or some more sx30s for my 30w box.
