Extra long VK battery?

[airpowers]

How long is this battery? I was also wondering if there has been any thought on a fatter battery. I smoked camel wides, so these batteries are very thin in comparison. I have also noticed that the cartomizers are a little thicker than the battery anyway. Just pondering...

It is no wider, but it's longer. It's almost as long as a regular battery with the cartomizer attached. See picture below

Seems to be about an inch longer? By the way guys, thanks for putting one in with my order! You are awesome! I love it and am puffing away on it now and even though it is longer, it feels good in my hand! I will be interested in seeing how much longer it lasts!

JenJen, it is my new Fav, for out, and about, it is 380 Mah, and lasts me 2 full carts. I am still waiting on the auto extra longs, but, we will not have them till after the Chinese New Year

Just something else to look forward too. I was comparing to my SD, GG, Prodigy, and really prefer it to all, right now

It has a little over 5 volts of juicebut, does not burn thru the carts, like the passthru's....warm, delicious vapor, like the Kools I use to smoke.

These put me in Vapor Heaven, hope it does so for you, as well

Now I am confused. I understand the longer battery is rated at 380ma's, but are you saying it puts out 5 volts?

Mark tested the manuals, with his eq. said like 5.07 or something to that extent

I find that shocking too..lol. The only way that could be possible is if it has 2 li-ions and a regulator built in. If so that's awesome but it would also need to have a boost circuit built in for charging. Or maybe it has a single li-ion with a boost circuit which would make more sense.

The manual PT was what test above 5V. The new extra long does have a 3.7V battery, but it does kick harder than the smaller batteries. I'm not sure why, maybe a little more amperage. I think it's also maintaining it's nominal voltage for longer. When freshly recharged I get a reading of about 4.25V for one of these.

I am not an expert on voltage or anything, but I know what I like. This extra long kicks ....! Oh yeah! Very nice! Charged it up last night and was puffing away on it all night, rotating with my passthrough. Going to take it to work with me and see how long this baby lasts! But definately am loving the way it vapors. I am going to order another!

 

[airpowers]

I am so getting one of these

 

[JenJen]

I was going to get a mod to beef up my 510, even had it on order. (Luckily I was able to cancel when I saw how good the VK was.) Honestly, with this battery I don't know why anyone would need a mod for the VaporKing. It really puts out the vapor. Definately going to have to get another!

Any plans to make a pcc for these monsters? That would make it perfection!

Yeah a lot of people get confused by all those voltage ratings...here it is in the nut shell..as it relates to e-cig batteries:

mah: milliamp-hours...IE, a measure of how long it will produce 1 milliamp of current..in this case 380 hours...this is a measure of how much current the battery stores and is a function of battery quality.

Voltage: the nominal voltage rating of the battery. The VK uses a nominal voltage of 3.7 volts. Important to note that when you activate the battery, it's staring face first into a virtual dead short..3.something ohms is very nearly a dead short. The more amperage the battery has available to it, the less that voltage drops when it stares into that black hole.

Amperage: The current available at a set voltage. typically when you throw a load on a battery, the voltage drops and the amperage increases..up to the capability of the battery.

The reason most e-cig batteries are measured in "mah" is to allow the purchaser to have a single number to compare batteries of the same type. It allows you to have a number you can lay hands on to compare duration of each battery in real world usage.

A higher mah rating indicates a higher amperage battery, but the voltage is fixed at 3.7 volts. because the only way the "mah" can go up if the voltage is fixed is by increasing amperage..you're left with the reason they produce more vapor. Since more amperage is available, the voltage drops less under a load (vaping a cartomizer) and more voltage is available than normal during usage as compared to a normal battery.

Did I mention I'm an Amateur Radio Operator? Batteries are a pet of mine.

*looks confused and twirls her blonde hair thoughtfully* Mmmhmmmm!

Like I said, I don't know anything about voltage and such, but I know what I like! lol

KC you are amazing. Thanks for the explanation. You explained it better than I would have. Here's the thing about the higher voltage and the VK. Even with the PT at 5V it burns through cartomizers quicker. I have tried some 6V stuff with the VK and the cart does not last at all. To get the maximum utility from your cart, I think 3.7-5 is the best option.

Thanks for clearing that up. The reason it kicks harder is because the more current the battery can deliver the less voltage sag there will be. Batteries are not only rated in mah's, but are also rated as to how much current they can safely deliver. Some LiPo batteries are rated at 30C or more...common for LiPo's used for RC hobby things like helicopters...

What this means is a 1AMP battery rated at 30C can safely output 30 amps. They will also have surge ratings....for example are good for 50C for 5 seconds. We are dealing with much smaller batteries and they are probably rated at around 5C with a surge specification. This is why the 5 second cutoff...its for safety, and also not exceeding it will give more battery life.

You recommended 5 volts as opposed to 6 volts. While I agree, 5 volts is still a little high IMO unless you have the money to buy a lot of cartomizers. Everyone has their own vaping needs. However the ideal solution would be to use two LifePo4 batteries and regulate the current to maybe say 1.4 amps or so. LifePo4 batteries have many advantages over Li-Ions. While they do not contain as much current compared to a Li-Ion of the same size, their C ratings are much higher. So given a LiPo battery has a 5C rating, a LifePo4 battery might have a 20C rating. LifePo4 batteries are also as safe if not safer than NiMh batteries. Another huge advantage is where the typical cycle life of a Li-Ion battery is 200-500 cycles, a LifePo4 battery has a cycle life of greater than 2000....meaning it can be recharged 2000 times before it needs replacing. This assumes it is recharged before 80% of its capacity is used up. The nominal voltage of LifePo4 is 3.2 volts, the charged voltage is 3.8 volts, and the cut off voltage should be 2.5 volts. Therefore LifePo4's would require a different charger which can be made for the same price as the ones we are using.

Anyway, sorry to ramble on and I could sing more praises for LifePo4's. but if Steve ever does decide to manufacture batteries in the US, he might want to keep this in mind. It would literally kill any other battery device out there for our VK's.

That is really not what the rating means.. It means it will be capable of sustaining 380ma's for 1 hour, and we would need to know the full specifications. For example what was the load used to come up with this rating...it could have been as low as .1C or as high as 1C.

 

[dfawcett]

Very nice KC!

Now lets see if you can consumerese the reduction in voltage for each drop in temp per deg. C? LOL Sorry I was the head of Compaq notebook tech support for too many years. ROFL

Good job

+1 but now you are addressing our world, not the consumer. I didn't even notice you post. Damn server busy crap. I swear your post wasn't there when I went to post, but it is time stamped from an hour ago!

Yeah the server busy is annoying but they will be moving everything over to a new server that can handle the traffic. I know most will not understand what we are talking about with all these voltage/current ratings. But for the few of us that do we could come up with even better mods than are out there. My first one will probably be made from a flashlight..lol. Thanks for your comment..

So, I got one of these. The length isn't weird, I can still depress the button and put my pinkie on the end, so I can see the light. It seems that the cutoff is about 3 seconds. I have a question though, when I turn the battery in my hand, I can hear something loose inside. This is my first manual battery, so I don't know if it is the button or what. Is this normal?
