I'm really confused by these two replies. Are they contradictory or is it me. Help!

Sorry about that. The battery under the carto connector drains first. If it reaches zero volts than moving it to the other slot won't work. If you put the battery under the connector in the other slot before it reaches zero volts than you will get longer life. I hope that is more clearer.

Thanks Terry//got it

Fresh Battery Readings.

Green Label Tenergy: 3.37-3.56
Blue Label Tenergy: 3.10-3.23
AW: 3.45 to 3.55

I'm not sure why we have a difference, Ufo, unless my batteries have been affected by long storage and or lack of recent use. The multimeter is a very inexpensive digital. I have two of the same kind and get virtually identical readings from both MMs. They have always give me what should be expected from fresh 3.7v and 4.8v batteries. I have other short batteries, 3.7v, Li-ion protected, UltrFire and AW, and one set of unprotected Powerizers I purchased with the Buzz Pro.

What voltage readings are others getting after pulling off charger and, also, after batteries have rested a bit?

The discussed LiFEP04 batteries are pictured below along with one of the Tenergy 3.2v chargers. BTW.... I'm charging using a 110v input to charger power brick.

Well. The Green and Blue Label Tenergy are 750mah (even if there is no written). Anyway, I suppose they are only nominal, because their effective autonomy is similar to that of the AW. which instead have 500 mah (many brands of batteries tend to write more amperage, even if the real value is indeed lower: in Italy we have conducted appropriate tests, to see precisely the difference between what is written on the battery and how much amperage is their real . Well, almost no battery respects the values ​​declared by the factory; the best are generally the AW cells that have around 96-97% of the declared amperage (not all of their models, though).
There are, instead, some brands that are even below 50% of their rated amperage (better for me not go into details, otherwise I risk annoying you:laugh:. But if you are interested I can put the link of the tests we have done)

The Tenergy about which I was talking in my previous posts, are of yellow color (I bought them as soon as came out the first batts with chemical Li-Fe-po, almost 2 years ago...... now, I believe that are no more in the market). Well, these Tenergy are exactly those who have given me more satisfaction..... even after so long are still perfect:), and measured as soon as they left the battery charger, they have almost 3.8-4v (even if, after some rest, they lose some charge, stabilizing at about 3,6-3,7 V

I hope I have made myself understood..... with my bad English it is not easy to talk about technical details:oops:

From the ECF Library:

http://www.e-cigarette-forum.com/forum/ecf-library/129569-rechargeable-batteries.html

Power rating for rechargeables

The critical factor for ecig mod use is the C rating (discharge current) in amps. The minimum possible value for safe and effective ecig use is 1 amp (= 1000mA) although ideally it needs to be higher. The ideal rating is 2.5A (2500mA) or better as an atomizer usually draws 1A to 2.5A.

Chart of C ratings vs size
Assume 1C for generic Li-ion unless otherwise noted
1.5C for ultra/sure/trust/-fire
2C for AW ICR (Li-ion)
3C for BDL 10440 IMR (Li-Mn)
5C for BDL 14500 IMR (Li-Mn)
8C for AW 14500 and 16340 IMR (Li-Mn)
10C for AW 18650 IMR (Li-Mn)
10C for AW LiFePO4
Tenergy LiFePO4 (small cells) - <0.55A (not suitable for ecig use)

Toss those Tenergy RCR123a batteries, people. Or put them in your flashlight.

No need to be sorry, Loren :) It's alarming...and something that folks should be aware of and it should be discussed. Especially for new vapers. Battery safety is very important regardless of what device or charger you use. Here are some useful links for folks to read.

While we don't know for sure the circumstances behind the recent exploding batteries....its always a good idea to exercise safety and caution when using any battery operated device, regardless of whether its a car, laptop, cell phone, flashlight, or vaping device.


+1000 on that,,,, but the feds love to advertise what happened dont they, FDA suxxxxx,,,,,,,, how come every Battery that goes into thermal runway doesn't have a news story ????

Ya...I'm waiting to see if this blows up into a bigger deal that those Chevy Volts that were randomly catching on fire....lithium ion batteries on board.

I think this incident is going to give a lot of firepower to the FDA. Since the guy used one of those commercially available 3-piece kits. Honestly, I already see the negative effects of this even in the ECF..........

I never saw any info about the 3-piece kit anywhere. The only thing that was found in the house was a charger and some CR123 batteries.
Mr. Holloway is also a photographer, so that might be why those batteries were around.
With that said, if the CR123 batts WERE used in a mod, then it would be obvious that he was stacking them to get a 6V vape. If the mod had no vent holes or protection circuitry, and the batteries were on a full charge or overcharge, and he was using a LR atty/carto, there is your recipe for a disaster.
Honestly, we need more info on this. The best thing vapers can do is educate themselves about how to use their devices and batteries correctly, and understand what the limits are. The vendors sure as hell aren't going to do it for us. Well, MOST vendors anyway. There are a few who know exactly what they are doing and sell a very good product.

Not specifically....in fact, its been reported that it was an electronic cigar. However....sensationalism tends to out do accuracy at times, so I don't really know. The one that occurred a last month was a Prodigy V3 if I remember correctly. Never saw any confirmed information on that one either.

I did see one of the reports about the current situation mention that it was an e-cigar as well, but I assumed it was a layman who did not know what a mod was, and equated the size of the mod to a cigar, hence "It was an e-cigar!"

We are all getting this information from the un/misinformed general media, and not from people who know what the heck they are talking about. On top of that, the information they are getting is second and third-hand anyway. I don't think we will ever know.

The saddest part, for me personally, and apart from Mr. Holloway's misfortune, is that I no longer want to buy a Buzz Pro. Why? Stacked batts. That's it. I know that Buzzkill@NotCigs REALLY knows what he is doing when he builds his mods and recommends batteries to go with it, but until he designs and builds a single cell model, I can't consider any of his mods. Poo!

according to a individual, that claims to be a close personal friend of the victim, on the puresmoker subforum it was a prodigy v3 using stacked cr123a batteries but nothing has been confirmed.
I heard it was an OMG mod from Vapor4Life.(last month)
