battery question

[Imnukingfutz]

I just ordered new batteries for my VTR, 18650's...I got the 4000 mAh Ultra Fire black & gold, the 2000 mAh I have now wont last all day.

I got the batteries via UPS yesterday from Amazon and they dont fit...they are 1/16 to 1/8 inch too long. These seem to have a nipple on the end whereas the originals have a flat top and the size of the nipple is the amount of it being too large.

Why the difference in battery size (length) for the same sized battery (18650)? Besides buying new batteries is there an adjustment screw in the VTR.

Is this what is referred to as a "protected" battery?

Hi

You really don't want to be using TrustFire batteries in e-cigs. They are ICR chemistry - the stuff that explodes and does bottle rockets if something goes wrong. And it sounds like you got protected cells. You need that for ICR chemistry - and it does lengthen the battery to get the protection in place. There are a lot of APV's that won't work with protected cells even if they do fit. Ok for flashlights, not a good choice for high drain e-cig use.

Don't cheap out on batteries - you whole vape experience it built on them, they get used and charged 24/7, and safety depends on them. (Don't even think about eBay...) Take a look at a place like RTD Vapor. We know them here, they are an ECF registered supplier, and they know what batteries to sell for e-cig gear.

I don't know the website that Rickajho mentioned, but you'll probably see that the batteries are "IMR AW". 4000mAh seems high to me (mine are also 2000), but I'm much too lazy to be an expert.

Any battery that claims 4000 mah is not a high drain or safe chemistry. The 4000 mah is an exaggeration in any case, only attainable if you are using it for a low power application.

ICR batteries that are protected have additional length for the protection circuit, so they can be too long for a number of mods. VV/VW mods need a high drain battery, which is typically an IMR or hybrid chemistry and don't use a protection circuit, so they are right around 65mm. I'd only use those protected ones in a fixed voltage mod or with higher resistance delivery devices, 2.5 ohms or higher.

Oh lord, just because a TrustFire battery says... anything you sure can't believe it. You have to check for a technical review somewhere like the candlepower forums to find out what their actual capacity is. I can pretty much guarantee their actual capacity - won't be that.

Those Ultra Fire 4000 mAh batteries are protected ICR batteries. They are a voltatile chemistry (meaning when they go into thermal runaway they vent flames and could explode, the reason they have protection circuits built-in to allow them to be anywhere near safe to be used in the first place; and the reason that they are larger than un-protected batteries). These batteries are not high drain or safe chemistry and have an amp limit less than 4 amps.

You want a safe chemistry and high drain battery for your VTR. The VTR uses PWM (pulse width modulation) to create higher voltage, so requires a high drain battery with enough amps to make higher voltage. PWM requires twice the amps of a user's set voltage/wattage because of the way the regulator makes higher voltage. Technical - Why high drain batteries?

The blog below has a large list of high drain, safe chemistry batteries more appropriate for you regulated mod:

DEEPER UNDERSTANDING OF MOD BATTERIES

* the NCR18650A 3100mah & NCR18650B 3400mah batteries made by Panasonic and Orbtronic are NOT high drain batteries and only have a 6.8 amp limit. Not enough for PWM regulation. These are best suited for flashlights.

I too have wondered about batteries on the who what and why myself when I first started using APVs and even more so on Mechanical Mods. The VTR is somewhat new and what is good about that? Well i'll tell you. There is a lot of protection built into your device, more protection than any battery that I am aware of and so what is recommended and what I have observed first hand is for most APV's the safest and best performer has been the orange aw batteries. Vape Rev has them. Actually a lot of venders list them on their sites and are out of stock on the IMR 18650 which is the one that is most recommended for the Variable Voltage/Wattage devices. NO battery is 100% safe but your chances are pretty good with the AW's. I know Vape Rev has them in stock because I just bought some IMR18650's and 18490's and I should get them today so if the site that members here recommend first are out of stock you have a good chance of getting them at Vape Rev. You do not really need protected batteries until you start in on Mechanical Mods. I have not had any trouble with the trust fire or EH brand but the do not last like the AW batteries do. Someone else in this thread said don't go cheapy on batteries and I would say that-that is good advice. As far as lasting all day the AW's should get you thru the day right off of the charger. Is it a problem to take a spare? If not then take a spare and be safe. Congratts on the VTR I just got my VTR yesterday. sighhhhhhhhhhhh I love vapemail! Happy Vaping!

Much like cigalikes are equal to two packs of cigarettes, huh? Darn - Santa Clause and Blus both shot down for me.

But Easter Buns is alive and well and right around the corner! We're having him for dinner - er - to dinner. (Crap. There goes another one...)

UltraFire is well known to drastically overstate the capacity of their batteries as witnessed in tests by the Battery Guyz.
For an APV you want:
Safe chemistry
Un/ Non Protected
Quality brand name
Bought from a proven reputable Vendor
Protected batteries sometimes don't play nice with the protection circuitry in APVs. The same as trying to run 2 anti virus progs at the same time on a PC.
Safe Chem batts are far more safe than Protected.

Thanks all for the info on the battery...I broke down and went and got a Samsung 2600 from my local B&M vapor shop...tried to save a little money by buying it on Amazon...thats what you get for reading descriptions of items...LOL

Live and learn.

Another good thing about my local B&M...he introduced me to his new igo w2...oh my, the flavors that thing gives off are amazing. A little too ahead of myself yet but now I see what I have to look forward to.

The Samsung Li-Ion 18650 3.7V 2600mAh-ICR18650-26F is again a protected ICR battery, NOT HIGH DRAIN and with a low amp limit, not that different from the 4000 mAh Ultra Fire battery.

The best batteries for your VTR will be a high-drain IMR or hybrid battery like what is listed in my blog.

I am going to get this battery thing right eventually...in the mean time I sure as heck have a lot of new flashlight batteries...LOL

This is the one I found in the Panasonic you listed.
Panasonic NCR18650PF 2900 mAh

Flat top..should fit?

I can't say from experience, as I don't own a VTR or those batteries. The VTR is known to have a low tolerance to 18650 battery sizes.

The Panasonic & Orbtronic batteries (essentially the same batteries, Orbtronics re-wraps Panny batteries) can be slightly wider in diameter and longer in length than typical batteries from other manufacturers.

Hopefully someone here who owns both a VTR and those batteries will chime in with their experience.
