List of 5 Volt PVs

[BuzzKill]

Welcome to Battery University

This site goes over ALL battery types even weird uncommon ones and It goes over safety, longevity , precautions etc.

These guys are true scientists regarding batteries !

I have yet to find any bad or misleading info on this site.
It is My University for reference .

There's nothing more disingenuous than trying to claim a flaw is actually a feature. NiMH batteries are inconsistent. The fact that they vary widely between fully charged and empty is not something to be proud of. This simply means that the vaping experience will vary significantly during the short life of the battery. In comparison, li-ion batteries remain relatively constant between full and empty. A regulated 5V mod (whatever the method of regulation) will provide exactly 5V for the entire life of the battery. That is far preferable to "somewhere between 5.8V and 4.5V" depending on charge level.

No, I'm definitely referring to NiMH. NiHM may have a less pronounced memory effect than NiCad, but it still exists. Li-ion, in comparison, has no special charge cycle requirements.

I would gladly amend my previous statements if any of them were inaccurate, but they are not. In fact, I'll say it again - NiMH is the wrong chemistry for e-cig mods. It is inferior to li-ion in every metric. I won't say that it won't work, but I will absolutely insist that it won't work as well or for as long as li-ion. This is a fact, and as such, cannot be considered "defamatory" under the accepted definition of the word. "Criticisim" might be accurate, but factual statements are never defamatory.

At the latter end of discharge I'd far rather be vaping at a strong 4.8V than a wimpy 3.7V.... still can't see how this is disingenuous just a preference.

The statement which I found to be particularly baiting was not your preferences of li-ion over nimh, but insinuating we use dirty tactics - maybe you didn't read the original quote in my post so I'll quote again:

'Of all the "tricks" that mod manufacturers have used to get 5V out of a mod, using an inferior battery chemistry has to be the dirtiest of them all.'

So you've implied we use dirty tricks - I think thats pretty defamatory or maybe you have another evasive answer ready..... I'm all ears...

You can see in this post that someone (who actually owns the device!) has told you that they get a very good experience from our custom 5V batteries in the Maksi, but still you insist on thrusting your own self opinionated, pre determined, black and white views on anyone who's willing to listen.

I think what you are referring to is not 'memory effect' but 'voltage depletion' which only happens if you use a charger which is unsuited to the battery. The charger we use has been specially designed to keep this effect to a minimum. And lets face it even rechargeable Li-ions gradually deteriorate over time - this is just par for the course with any rechargeables.

As I stated already, I'm not doubting that li-ions have more potential over nimh, but you're comparing a technology still in its relative infancy (li-ions) vs. a technology which has been perfected and is comparatively stable. Both have their advantages, but to rule one out completely as obsolete for no reason is just nonsense.

The main point here is you haven't tried the battery and you are going by theory alone..... we spent many months testing these batteries to make sure that they were up to the job so all I'll say is: don't knock it til you've tried it.

And if you're not interested in giving it a go you could always listen for a minute and let real people who have tried it a chance to speak.

Well put smokindeuce. This was the point I was trying to make. The unit is very satisfying using this battery and once it starts to fall you just drop in the newly charged batt and you're ready to go at 5.75 again. I got 2 1/4 hours of non stop vaping out of my battery and that's as good as many 3.7v batteries can do, so I'm very happy with the performance. And for the price, I bought 2 extra sets so no problems with having one ready to go. If I go out I use either the 3.7v or 6v depending on how long I'll be gone, but at home with my charger next to me the "5v" batt is great.

PS. Is that you Tim? If so, I'm John that you've been corresponding with.

Cheers.

Hi John

Yes some people like to talk the talk before they've even tried walking the walk....

Here is a recent video from someone who has walked the walk:

Comparing a single li-ion cell to four stacked NiMH cells, that's an accurate comparison.

The statement which I found to be particularly baiting was not your preferences of li-ion over nimh, but insinuating we use dirty tactics - maybe you didn't read the original quote in my post so I'll quote again

Maybe you didn't read the inaccurate post that started it all, so I'll post it again:

The Mako is AFAIK the only TRUE 5v device in the whole list as it uses a 5v battery instead of some kind of electronic modification or resistance trick (read wasted power and lower battery life due to heat) to achieve 5v.

See what I did there? It's called a "callback". I used the same loaded term that uneverno used to point out how silly his post was. As I said earlier in the thread, "There's no such thing as a 5V battery". Every 5V mod has to create 5V with some method. If you want to call stacking batteries a "trick", then the mako is just as tricky as any other mod. Though at least with other "tricks", you're not getting an inferior battery chemistry.

The main point here is you haven't tried the battery and you are going by theory alone..... we spent many months testing these batteries to make sure that they were up to the job so all I'll say is: don't knock it til you've tried it.

And if you're not interested in giving it a go you could always listen for a minute and let real people who have tried it a chance to speak.

Theory that has been rigorously tested and repeatedly proved accurate is not "theory" - it is fact. That NiMH has low energy density, suffers from a wide discharge curve, and exhibits memory effect issues when deep-cycled is not a matter of opinion. Even the "real people" who have tried it say that the batteries need to be swapped frequently (every 2.25hrs!). Compare that to a 5V regulated 2x18350 setup (which I do have) that will easily go all day without a recharge. Even a 2xCR2 setup - which has about the same battery volume as the make 5V battery - will last most of a day. I don't need to buy a mako to know that the longer, more consistant vape of a true 5V mod is superior.

If you've already got a mako and you don't mind the poor battery life, then more power to you. But anybody considering buying a 5V mod deserves to know the differences between the options available. All 5V mods need to use some sort of "trick" (see there? I did it again) to get a 5V output, and not all methods are equal. In order of superiority, these methods are:

1. 2x3.7V li-ion batteries, PWM regulated
2. 1x3.7V li-ion battery, boosted
3. 2x3.7V li-ion batteries, linear regulated
4. 2x3.7V li-ion batteries, voltage-dropped with a resistor or zener diode
5. 4x1.2V NiMH batteries

The method used by the mako is the least desirable method. The reasons for this I have already pointed out in this thread. This is not an opinion, it is fact based on the laws of physics. Again, it's not that the mako doesn't work, it just doesn't work as well as other mods.

Well I'll leave it at that Candre....check the vid above - if you're not chaining it these batteries will offer a half decent runtime.

We could argue til the cows come home and of course I agree that li-ions have some advantages... however when it comes to stacking unprotected li-ions vs nimh to get a 5V experience I know which I'd opt for in terms of safety.

There's no such thing as a "5V battery", especially not with NiMH chemistry. It's either a 4-cell 4.8V battery or a 5-cell 6V battery with some kind of regulator built in. The very low capacity (400mAh) would certainly indicate a stack of much smaller cells. So the Maksi uses all the same "tricks" as a regular li-ion mod, they're just bundled up inside a battery pack instead of out in the open. You also have to deal with the memory effect and low discharge rate common to all NiMH batteries as well.

Hey guys, check out this electronic cigarette: Direct E-cig

It looks like it is an RN4081 but it CLAIMS to have a 5v battery.
Yet it appears to be the size of a regular RN4081 battery.

Impossible?

 

[Elendil]

It's still good to see that they believe 1 cart = 1 pack analogs.

Sure it's 5v (if you run 2 of them in series)

 

[candre23]

Impossible?

Improbable, but not impossible. They could be using two very small cells in series with a simple resistor, but the battery life would be atrocious. This site reeks of scam with their automated billing scheme, and at $30 a pop, those batteries wouldn't be worthwhile even if they do put out 5V.

You need to add "The Buzz" from not cigs.

 

[chev327fox]

You left one out

LOL.... great list for people to have though. Nice Job!!!

Buzz

I tried to add the Buzz to the list but I guess I edited the list as many times as I'm allowed to - the "edit" button is gone. I did buzz the Buzz somewhere in the thread, but you know, if the comment isn't on the first page or the last page not many people will see it.

Anyway, I started this list because I was looking for a good 5 volt device. So, funny thing with the Buzz not being on the OP list, I settled on the Buzz. It is awesome. Hands down the best PV I've ever had. And with the ability to adjust the voltage to any level I want between 3.7 and 6.0, I've found that 5 volts is actually really not the sweet spot 99% of the time. 5 volts is just as close as I've ever been able to get to the sweet spot before the Buzz. My sweet spot with most juices is usually between 4.3 and 5.2 volts - you'd be surprised how small voltage differences can impact the performance of a juice.

Anyway. The Buzz. It rocks. Highly recommended. I'll never mess with special HV or LV atomizers again - I can just tailor the voltage to whatever works. Great quality, great design, great PV. The only thing I'd change is that it is about 1/4" longer than it needs to be in order to accommodate different battery sizes. Everybody (accept somebody out there) uses protected CR123's so shave that extra 1/4" off the tube to tighten the whole package up!

Also, did I recommend the Buzz yet? THE BUZZ.

Oh, also, in my previous post about the Buzz I said I was really looking forward to seeing if it could deliver consistent voltage throughout the life of the batteries. It can. It rocks. If I set it to 4.7 volts I will get 4.7 volts the whole time. The voltage the Buzz delivers doesn't drop off as the batteries die...until they are dead. You set the voltage where you want it and go. Soooo nice.
