Okay thanks. Just got an email back from ikenvape confirming they measure at 3.3. What do the tenergy batteries measure at after you take them off the charger? The same? Just curious.
How many hours does your prodigy V3 last?

Actually, when AW LifePO4 batts come off the charger, they are around 3.6V. Within seconds the voltage starts dropping pretty quickly and within just a few minutes they settle at 3.37V-3.38V.
I'm a little afraid to blow an atomizer with that high of voltage. My guess is that the tenergy rcr123a batteries come off the charger around 3.2 or 3.4 also. But Cant confirm it.
It's important to understand that this is the unloaded voltage. I use these batts on my V3 and P18 and the voltage under load is close to 5.5V. You really don't have anything to worry about. I never use these batts when they come off the charger because they last me 7-8 hrs but only take about 1.5 hrs to charge. If you ask most experienced HV vapers, most likely they will advise you that AW LiFePO4 batts are the only way to go.
I just measured my aw lifePO4 batteries right off the charger all 3 that say LifePO4 500 Mah 3.2 measure at 3.33. The one that just says LifePO4 500mah Measures at 3.80 and started dropping fast when testing to 3.79.

Tenergy LiFEPOs will measure the same as AW, they are very similar to the AW (although not quite as good quality).
I've been using the Tenergys for many months now with no issues at all. Just like the AWs, they come off the charger at around 3.4-3.6 and after the first couple of uses, tend to go down to 3.4. They are excellent batteries.
Main thing to do is to keep them in pairs. If one of the batteries in the pair starts misbehaving (overcharging, discharging faster than the other) - discard it.
I would discard your one that is measuring 3.8 too.
You will not pop atomisers with LiFEPOs if you use the correctly rated atomisers and keep them wet but not flooded.

Ya I am going to get a new one. I dont want anything that is measuring at 3.8 off the charger. Thanks
what charger are you using? i've seen 3.8V coming from the Tenergy charger before, but not from the Ultrafire WF-138A that Ikenvape carries. if you are using this charger, which you should be, are you making certain that the charger is set to 3V and not 3.6V. at the 3.6V setting the charger wants to charge the cell like a conventional lithium cobalt chemistry, 4.2V. because the chemistry of LiFePO4 batteries give mixed signals to a voltage detecting charger like that, it likely won't end up at 4.2, but could come off the charger at 3.8V or higher. all lifepo4 batteries have a nominal voltage of 3.2V and all of them should be charged up to 3.6V but never higher, most coming off the charger between 3.4 and 3.6. the only "3V" cell in that size (16340) is the Tenergy protected battery, that claims 900 mAh. that battery requires a special charger altogether to account for the diodes restricting the output voltage from a conventional lithium cobalt battery down to a 3V battery. wasted space in the circuitry and wasted energy as heat means even lower runtimes, which along questionable discharge specs amounts to a less than desirable battery for vaping. as others have suggested, if one of your cells is reading 3.8V throw it out. the chemistry of the battery is not suitable for charges that high, and exceeding the the maximum voltage like that can create more problems than simply blowing an atomizer.
stick with the AW LifePO4 batteries, use the Ultrafire WF-138A charger at the 3V setting, and continue to check voltages before and after charging. i think you'll be pleasantly surprised at their performance over time, and with attys at around 3.2Ω and slightly higher, you'll get a great vape and will seriously decrease the likelihood of popping atomizers that might not have fared as well otherwise at 6.4V off the charger and approximately 5.5V under load.

Yep, I agree with ya buGG. I love my AW LifePO4s with a 901 at about 5Ω though. They seem to last me forever with that high of a resistance too. I have been simply using my Tenergy LifePO4 charger. I keep my WF138 set on 3.7 for my AW IMR 16340s. I know AW suggests that charger for the LifePO battery but I wonder if it actually charges them enough.
