problems with mods ?

[D.WILL]

I think I did a booboo. I'd put my mods together and stacked my
batteries 18650 and now the firing buttons get hot on both of them I know I wasn't suppose to do that just want to try it out did not leave them long only a few vapes and now they get hot and u have to push it a certain way now ... My mods r a chi-you clone an a Pisces clone did I messed up the batteries or ky mods this way I know what to replace or fix ...

Stacking batts has it's drawbacks.

 

[buttsak]

Do you mean 18350? I can't c stacking 2 650's

 

[serenity21899]

Either way, battery stacking is just a bad idea, especially if you don't have the tools (multimeter) to monitor the batteries properly. Someone will come along and give the technical explanation, I'm sure.

 

[buttsak]

Well I use 2 350's in my SVD but its regulated sooooo yeah. But I do know that stacking increases amprage which could b bad in mods

If batteries, the fire button, or the mod get hot, you've got a problem. Somewhere there's a short, or a battery is being pushed beyond it's limits. Anytime you do something out of ordinary you run the risk of doing something wrong. Putting mods together for stacked 18650's? Now that's a new one I hadn't heard of. I hope that you now realize that this act was idiotic and dangerous.

It's not hard to research on stacking batteries. The majority of references will tell you to NOT TO STACK BATTERIES.

Despite this, there are those who do stack batteries. They know the risks involved and are willing to accept them. They have a methodology of mating perfectly matched batteries, paired for life, and alternating each one in the order that they are put into the mod. They check the voltages of the batteries coming out of the mod and coming off of the charger with a multimeter. It's a painstaking process to do it right, and to do it every single time.

OP didn't say what batteries he was using. Brand name, model number, type of chemistry, amp limit? What's the resistance of the coils? Oh, that's right, you don't even have a multimeter.

Please, PLEASE, never stack batteries in a mechanical mod (or a regulated one for that matter) If any thing gets hot like you are describing, take the batteries out, put them in a metal bucket someplace safe outside where if they do decide to vent they will not cause a fire, DO NOT PUT IN WATER!!!! or let rain or snow get on them -

come back inside, and search for new batteries ( here, I'll help - Amazon.com: (2 Pieces) 30A Sony 18650 Battery 1600mAh 3.7V High Drain US18650VTC3: Cell Phones & Accessories )

Write those stacked batteries off as a lesson learned and make sure you dispose of them properly (do not put in garbage) as they are now unstable and dangerous

Without pulling charts or getting too technical. When you stack, you're doubling the voltage but depending on the resistance of your coils,you could be tripling or more the amp draw. Its a pretty dramatic increase. Pulling too many amps causes all kinds of dangerous issues. Scrap the batteries and consider it a learning experience. The what NOT to do kind.

 

[Baditude]

Batteries pack a lot of stored energy in them. If they become stressed or abused, they can go into thermal runaway. They can vent extremely hot gases, vent flames, or explode.




It seems inevitable that someone is actually going to blow their face off by doing something foolish and not recommended with their souped-up mod trying to make giant YouTube clouds, make national headlines and thereby putting the whole vape community in a bad light with the general public. It only takes one to ruin it for everyone.

 

[D.WILL]

We'll the problem I'm having now is that the firing buttons r getting hot when I use my mods and I only stacked them once I know it was stupidto do I just want to know if the batteries r bad now or the mods the batteries take charge and worked fine they don't get hot the firing buttons do I guess I will have to get new batteries and I would like to apologize to the vaping community u lesson learned

Wait... At fixed resistance, voltage and amperage are linearly dependent... What you said is just not true unless theres some electrical wizardry i am missing, in which case i ll be delighted to be educated.

 

[Kanj.nguyen]

Now, since no-one is actually explaining to the OP why the button gets hot, i ll do it. When you stack batteries, you are pusing twice as "heavy" a current (double amperage) through the circuit. The circuit in this case is the metal body of your mod and atty. This metal body, in particular the button, has a resistance, however small. When a current goes through a medium with resistance, some electricity turns into heat energy, i.e. the medium gets hot. With a single battery, this is not an issue. With stacked batteries, since the current is carrying twice the electrical energy, the button gets very hot to the touch.

Stacking batteries is generally a bad idea. However, even with single battery the button of your mechanical mod may still get hot - in principle 1 or 2 or 100 batteries behave the same way except for changes in constants. When the button gets hot, open the switch assembly up, clean everything inside with a clean rag or even warm soapy water. Wipe with cotton towel. Essentially just clean the contact points to reduce resistance in the switch.

stacking batteries ( series) in mods do not increase amperage it increases voltage to get more amps, batteries are run in parallel...
But it does sound as if you may have done some damage to the batteries if THEY got hot in the tube if just the switch got hot, it is a sign that alot of current went thru the switch and possibly pitted the switch surface thus leading to reduced contact area and therefore increases contact point resistance aka heat check the switch surfaces... and dont stack batteries in mechs until you know for sure what will happen when you push the button

Many chinese clones have the problem of the button getting hot with high amps. its a bad idea to stack batteries, but even a really low ohm coil can do the same
