Anyone prefer 18350s over "650s?

[vsummer1]

Stacking batteries is generally discouraged because while it can be safely done, the steps that must be taken to do it are extensive and the penalty for breaking the rules can be disastrous.

Why must people talk about things making them seem so bad when they are simply not? IF a chip is designed to deal with it, it deals with it. Just because the stuff from China isn't made to handle it, it doesn't mean there aren't some from the good old USA that are.

As a general rule, no don't stack '350's but there ARE things designed to handle it and they perform very, very well with no more danger than any other battery configuration.

You make it sound so hard to do! I label each of my batteries as it is, '650's included, and rotate through them. I see no difference with stacking them, you merely label pairs. I have mixed my pairs up and I wasn't zapped into another universe or some such terrible thing. They worked just fine even cheating on one another using your marriage analogy. I don't bother with the other stuff you say I must do either and I have had no, zero, none adverse events. My fingers are all accounted for, my face is intact, and nothing has been on fire. Because I use a PV that was designed to use them, has been in use for quite a while by many happy vapers, and nothing bad has happened to anyone (unlike the chinese batteries which don't even use stacked, but that is another thread).

All that said, FOLLOW YOUR PV'S INSTRUCTIONS and don't stack batteries willy nilly. Use common sense and you will be just fine.

I split the difference and use 18490/500's mostly. Only my cartopipe gets a 350, and only my SB gets a 650. Everything else runs off a 490.

Oh and why stack batteries when there isn't a damn thing that can be done with stacked bats that can't be done with just one. Stacking batteries came about back when it was the only way to boost voltage above what could be obtained from a single battery. Those days are long gone.

The real problem with stacking smaller cells is that it will only boost voltage ... not amperage. This makes stacking a total waste of time with our modern delivery systems. If the small cells are only rated at -5amps, you could stack 10 of them ... you would still be stuck with -5amps.

The issue is that in today's society, almost no one reads instruction manuals. Also at issue is the fact that few APV's come with a complete instruction manual that includes warnings that are at the front of the manuals for every cell phone, laptop, tablet, microwave, etc. Those manuals tell you what not to do with your device and warn the user of the risk of fire or personal injury if the device is used improperly.

There is a reason why a curling iron manual warns against using it while in the bathtub.

Sooner or later, some knucklehead is going to rip open the package his new APV came in, toss aside whatever manual came with it, drop in two batteries of unknown quality, manufacture, capacity, condition or charge state and mash the fire button to drive his freshly built 0.5 ohm coil.

Then the local news will interview him from his hospital bed, show disturbing pictures of painful burn injuries and have him proclaim that these e-cig things are not safe.

You obviously know what you're doing. You're obviously taking sufficient steps to insure safe operation. I would wager that you are something of a minority.

I prefer the 18500 hands down. Its small and carries a MAH thats respectable. I do however own and use 350 & 650's. There's a time for each battery size. Going out I use 350's, work I use 650's. Any other time I use 500's. It also depends on the mod. I use a sigelei V3. Fantastic telescopic mod. I can actually use the large battery cap and a 500 in 350 mods (screwed all the way down). Thats the best and smallest VW setup ive found. Much smaller than the vamo and evic. Not sure if its been mentioned but the itaste mvp has insane battery life. 2-3 days. Its quite small too. In my jeans the 5th pocket carries 4 18350 or 3 18500 batteries. I just load them up before I leave the house and im good all day.

 

[WhiteHighlights]

Back to the original question - I prefer the 18350s for the form factor. I have small hands so the balance and fit of my ProVari with the 350s works for me. I might be able to get a little more bang for the buck with a 650 but if it's not comfortable, it's not worth it to me.

 

[unsure]

I can't pick between the 2 because I use them both in my 2 favorite mods but if forced to choose the 18650 for it ease and longer life.

 

[MoonLit_Water]

I use 18650 in My eViv, 18350 in My VAMO. I also have an evod 650mah. Depending on my mood and or situation I choose the device that would best suit My needs and desires at the time.

variety is a good thing

In regards to this:

This is why some will chime in and say "we need more laws". "we need more testing".....on and on, these are also the same folks that need to be told when to wipe their own rear end"

So I said it before someone with the Moronic Plague jumps in!

I just want to go and vape:

I think everyone should read the article from the Florida idiot that had the battery reaction.

There is a doctor who comments on testing, and FDA regulations necessary for e-cigs..

This is exactly what I was referring to...

We don't need any more regulations or any more rights taken away, or any more government intervention with our "Life, Liberty, and The Pursuit of Happiness"!

What's fricken next, you'll have to take a "Blender Safety course" to own a Kitchen Aid Blender...these people are nuts!

GO HUG A ROOT!

ARGHHHHHHHHHHHH!

Oh geez! I just read the Fla. artical and SOOOO many red flags go up on some of these Dr. quotes.

"While the devices go unregulated, Americans who purchase e-cigarettes do so at their own risk, said Dr. Stephen Jay, professor of medicine and public health at Indiana University."

No kidding genius!!! You take medications at your own risk these days. You swim at your own risk. You bike at your own risk.

"These products, based on what we know and don't know, should be regulated now," said Jay.

You don't know anything about them (and what you do know is darn little) yet we need to regulate them??? Why? For the sake of what you MIGHT find out? No thanks!!!

"There are no data regarding either their safety or effectiveness as an aid in tobacco-use cessation. Claims by manufacturers and distributors are just that - claims. The Internet is awash in pro-e-cigarette advertising [and] much of it is very misleading and aimed at vulnerable young people."

WOW! Are Y'all reading this? Seems all the people I've read about quiting here on these forums are liers. And they have to all be young people. That what the "experts" say.

Dr. John Spangler, professor of family and community medicine at Wake Forest Baptist Medical Center, agreed that the FDA should regulate these products.

Again why? Because you don't know anything about them?

"Anytime someone inhales a vapor of a drug administered by an electronic device, there should be strong evidence that the device and drug are safe," said Spangler. "I personally believe that the FDA should require safety studies on electronic cigarettes and should regulate their use."

Oh you mean like some of these "safe studies" they do for these pharmaceuticals that WIND UP KILLING PEOPLE!!!!!!! Oh, and by the way....YOUR ONE OF THE ONES WHO PRESCRIBES THESE MEDICATIONS!!!!!!

The FDAs track record as a "safty net" for the American people isn't what I would call good. I wouldn't trust them to regulate my dogs food.

 

[Coastal Cowboy]

A little off topic, but if the FDA's track record for pharmaceutical safety were an airline, every prescription medication would be grounded.

The safety record of AW IMR batteries, in all sizes, is exceptional.

Batteries explode, just like anything else they have a limit. Whether they explode because of human error (more likely than not) or simply because they malfunction poop happens. The only thing IMR batteries have going for them that others do not is that they vent and don't flame up and lead to combustion. There have been dozens of cases of "AW" batteries venting, don't tell people buy AW and you'll be safe that's a bunch of bull, batteries should be taken care of properly.

 

[_sidekick_]

Now can anyone explain to me why they MUST be kept in pairs? I really don't understand why that is necessary. If I pull any two AW 350s off a charger, why can't I stack them?

I'm genuinely curious, I couldn't find anything on google.

The only reason I do it is so I don't use one set more often than another. I just like to keep the batteries in rotation. Also, it allows me to make sure I rest them after I charge them by not being confused as to which set goes in next.

I'm not saying you should stack batteries, but every time the topic comes up there's a lot of DON'T DO IT and very little reason why. The main concern is that one battery discharge into the other uncontrollably. For this to happen they would have to be at different charge levels. And/or have wildly differing internal resistances making one discharge faster than the other, leaving them at different charge levels. There seems to be some exaggeration in regards to this, as the discharging battery would be under load, effectively lowering it's voltage and thus decreasing the voltage difference.

Another factor could be wildly differing capacities. Once they reach almost fully discharged, one battery could topple over the low voltage point of no return and start doing funny things.

Again, not saying you should stack batteries. Don't blame it on me if you absolutely must and end up getting blown up.

 

[Snickerfritz]

I prefer to use my Vamo is short mode so I usually use the 350s. The battery life is definitely shorter though. It isn't a problem for me since I scarcely ever leave the house so I just swap 'em out.

its a similar reason you get all the "DONT DO SUB OHM" comments. its usually people who read it somewhere from someone who also read it somewhere and have never actually done it themselves. keeping a pair of $15 batteries together shouldnt be any harder than figuring out what to do with the little plus and minus sign when placing batteries.

people stack batteries all the time. there are more devices that use stacked batteries than a single one, and this includes lith batteries.

as for 350s vs 650s i use button tops for single batt mode and flattops for stacking as to distinguish when sorting/charging. when im out i normally carry x6 but if its a restaurant or someones house i bring my vamo in short mode with a 350 and keep a pair of 350s in a plastic case. I just flip them the opposite way when i put the discharged ones in the case to know which ones which without looking.

also. i make sure i switch to my single coil low ohm cartos.

 

[ItTechy]

OKAY OKAY

Enough theory, It's battery chemistry people, not stacking that causes the KABOOM!

Li-on are safe to stack as I said I stacked Tenergy RCR123a' all the time , even different mAh, but these have a proven track record of being safe when stacked....

Do the research, YES it is very safe to say JUST don't do it unless you do your research!

The different mAh has nothing to do with a battery exploding, it's how a battery reacts during load and discharge, and also during charging.

Alkaline batteries were not designed for fast discharge for instance.

Battery design people and chemistry!

It's as bad as saying nicotine causes cancer, well I guess if you add 4000 chemicals it was just guilty by association!

When was the last time you heard about little Johnny on Xmas day getting burned because his Sparky the battery operated dog blew up when he made it bark repeatedly?

Also when was the last time you saw any consumer electronic device that used Alkaline batteries advise to stack them?

YOU DON'T


No then a flashlight IS NOT considered in the same classification as a consumer electronic device, it's a flashlight, and many stack alkaline batteries, and they don't blow up either!

FOR INSTANCE:

A flashlight has a calculated draw based on the bulb, which can be one or two types lets say per manufacturer..

Both Alkaline and Lithium cells have been proven to work in these scenarios without problems.

Surefire tactical flashlights have been stacking batteries for years and no police or service members have EVER BLOWN UP FROM USING THEM AS DESIGNED!

No them, a e-cig mod is quite a bit different, it is a super high drain device, it taxes the crap out of a battery, so you have to use the RIGHT battery!

If you had a tube long enough for two 18650' you could vape safely on any higher resistance carto for instance, and then there are the protected batteries, specifically designed to PROTECT themselves from overheating and adverse reactions due to over volt or under volt conditions.

WHEN ALL ELSE FAILS: RTFM


Manufacturers test their devices, and tell you what you can and cannot do, hey if you want to hook your mod up to 440 v AC, I guess it might hurt you! Same with any device, battery or AC powered!

Go ahead hook up a office copier to 220 AC, nice firework show, or hook a high capacity device designed for a 20 amp circut to a 15 amp circuit...Oh you can do it, trust me I have seen many fools do it (hook servers into 15 amp circuits, etc. with large UPS')...

People amaze me, jump start a car and reverse the battery cables from one car to another!

Electricity can be your friend, it can also KILL you!

RTFM RTFM RTFM

Sheesh.....

YOU CAN SAFELY STACK BATTERIES FOLKS!
