Battery Question

[Vaporologist]

The price showing on Ikenvape for the AW Blues is that per pair? Pricey if single, but you get what you pay for as mentioned.

The price is for a single battery. $7 may sound like a lot but it's really not, considering the fact that they will last you for no less than 6 months and possibly longer. After all, we used to pay that much for a pack of stinkies which would only last about 1/2 a day for some of us

Quality batteries are crucial for safety and an overall great vaping experience. IMO purchasing the best battery available is the only way to go.

So true, and for a halfway quality cigar in my case so shouldn't complain. But being I'll be starting a new supply of them it's like getting a box of of good Cubans. Guess it will have to wait until next week to make my order. Would like to try out the Mega 808's when he gets them in again.

Have a good one....

The price for vaping pales in comparison to what I use to pay for premium cigars

I couldn't believe it $75.00 a carton wow, you can buy allot of batteries for that.

 

[Iken]

The funny part is that we supply these batteries at the absolute minimum price. A quick AW16340 google search will show you 10.95-14.00 for just one.

Thats the thing Switcher, they say to stick with the same batteries and same charger, but I believe it's just a marketing ploy (I could be wrong)I see two things in a charger, amps and volts.A WF-138 has an output of 5.2V, but so does a cellphone charger. Most batteries have the same size generally has the same output as amperage.This could be ignorance talking. It just doesn't make sense on Why does a specific 16340 charger has to be used on specific 16340.

After reading thru Charging lithium-ion batteries

Stage 1 involves applying a Constant Current (CC) to the battery, followed by a Constant Voltage (CV) in stage 2. The CV is applied until the current needed to maintain that voltage drops below a certain threshold. This CC/CV charging algorithm implies a "max current" that should be applied to the batt, the page says 0.5C. How many amps that actually is depends on the battery capacity/size. Seems like it would be "safe" to charge a high capacity battery with a charger designed for a lower capacity battery (would just take longer). But the inverse is probably not a good idea.

Anyway... I think you have to be a little careful about matching the charger to the battery capacity. Putting a 10440 in a charger designed to work with 18650s is a bad idea. The CC applied in stage 1 will be toooo high.

Also from looking at the specs on IMR batteries, they support higher charging currents (as well as discharging rates). The 16340 and 14500 IMRs say 1.5amp as the max charging rate. So I think it would be possible to shorten stage 1 time for IMRs given a charger that applied a higher CC. I haven't seen any hi-rate IMR specific chargers, but it seems like there could be such a thing. Personally, i think the 16340 IMRs charge quickly enough in the WF138 (which is designed for ICRs). And given the CC much below the "max charging rate" for that IMR batt... i think thats a super safe combo.

Which I did do! But since you are now out of the WF-138 chargers I'll hold off on the bat's until you get them back in. Any idea as when you will have more of them in? Anyway, just to keep you busy, finished an order for some Mega 808's and a few other items. Sheeet.... had to buy something to tend to the let down of no charger and batteries.

I can't believe how the school kids can afford to be smoking when the prices are so high. Can remember when they were like 35 a pack.

No fooling hu Switched! But there are times I truly miss them. I've got a couple special ones tucked away in a well maintained humidor for when my daughter gets married. Didn't think they were going to see that day a few times over the past couple months, but fought off the urge with a good heavy 6V vape.

I totally agree Madness, a designated charger for a certain type of battery to an extreme such as 18650 to 10440 should not be used. Because in order to accomplish a feat like that would need a modification for the article to fit. The topic at hand is Tenergy's claims of 16340/123a in general requiring different types of chargers that I have to disagree with. I believe that a WF-138 will charge any 3.0-3.7V 16340 sufficiently with the appropriate flick of the switch.

Aww I'm sorry Greg! They'll be coming soon. I'm just waiting on my electronics gal.

I have a question for battery experts here. I have recently purchased a glv2 mini and I'm using the black aw 16340 in it, with ikenvape's 510 lr atty. I don't notice any difference from using a standard atty on an ego. Do I need to use the high drain battery aw imr 16340.

I also purchased the glv2 5v mod that uses 2 aw 16340 protected batteries. Will performace improve with aw imr 16340 batteries?

The IMR for LR will definitely show an improvement on the mini. The aws for 5V are good as that is what I use for 5V myself. There at their limit using HV and XHV attys.

 

[badmemory]

Thankyou Switched as much as I guessed, you just confirmed it for me. I will have to order a couple of aw imr's from ikenvape as soon as I can.

I have the WF-188 charger, and ordered the Tenergy RCR123A 3.0V 900mAh batteries from the sale @ IkenVape.

I tested 4 of the batteries as they were BEFORE putting them in any charger with a Craftsman digital MM. The voltage on 4 3.0V batteries before charge came out to:

3.962V
3.845V
3.820V
3.845V

From what I read, 3.6V is supposed to be the fully charged voltage for these batteries. I have another set of 2 that I have been using @ 6V on a PV. The charged voltage fresh-off the WF-188 set @ 3.2V / 300mA, unplugging the charger with the batteries loaded, and then, plugging it in with the batteries in, and allowing them to charge came out to:

3.747V
3.769V

Personally, due to the readings on these, and the other batteries, I see nothing wrong with using the WF-188 charger. I have touched the batteries throughout a charge cycle, and I have yet to feel a hot or even very warm battery.

Not saying it's proper.... Just seems to be working for me...

I have been advised that both, the WF-138 charger set at 3V and Tenergy charger (the one for LifePO4 batts), can be used for charging both Tenergy LifePO4 and AW LifePO4 batts.

Edit: Also, here is something interesting I read earlier today that I was not aware of:

"The WF-188 can auto-sense a battery's voltage and charge rate and adjust to that battery, thus you can charge two different size batteries at the same time, but the batteries must be in the charger before you plug it in for the auto-sensing to work. This instruction is in the documentation that comes with the charger."

Hey Techonut, I don't own the WF-188 charger since I use the WF-138 for my LiFePO4 3V batteries. The Tenergy batteries you are describing are not the LiFePO4 chemistry and will charge differently. LiFePO4 batts do get warm during charging...

I suggest you read the techno information for the Tenergy site. These batteries charge to 4.1-4.2 when fully charged, using the appropriate charger. I wasn't too fussy about acquiring another charger when I got these. I've been using mine well over 6 months without problems.

When searching for batteries, it is also important to not only look at the overall mAh and voltage of batteries, but some actually mention their MAX discharge and charging rates. I believe the latter to be more important than the charger used.
