E-Power 14650 down-regulates the voltage too far!

[Maast]

I just bought a 14650 direct from Smoketech the one with the 5-click on/off switch that can take LR attys (4th gen switch?).
No-load on my shops Fluke the AW 14670 battery reads 4.18V, when going through the switch it's reading 3.61V. I get similar results using the generic batteries it came with and other AW 14670 batts. Its dropping it a full 5 volts.

I've ohmed the case and spring and I'm getting good contact, I've also put noalox conductive anti-seize/oxidation grease on the threads to ensure good conduction. It has to be the switch.

God knows whats happening under load, I need to get an 510 extender and make something with contacts I can clip to. BTW (to my disappointment) the AW 14670 batteries are NOT high drain batteries. Dammit. Anybody know where I can find high drain batts in the 14650 formfactor?

At any rate its not an absolute show stopper, I can switch from the 2.0 ohm dual coil XL cartomizers I get from Nhaler to 1.7 or even 1.5 for equivalent wattage heat production but I'm quite disappointed.

Is there any way I can adjust the regulation? For that matter how about modifying the switch to just connect the battery with the atty without any regulation at all?

How do you figure it's dropping 5 volts? The batteries arnt even 5V to begin with.

Why would you even want to make it unregulated? All that would do is put out around 4.0-4.2V right off the charger, and then performance would just decrease as the battery drains, and toward the end it would be putting out closer to 3.0-3.2V.
That's what the Riva does, starts at 3.7v off the charger and then slowly drops to about 3.0-3.2V, and it's def a very noticeable difference in vape between a fully charged battery and a battery that's almost dead.
At least with the Epower being regulated it gives a pretty consistant vape as the battery drains.

Yes the AW 14670 batteries are not high-drain batteries. They are just regular protected batteries. Regardless they are a good battery though. If your looking for high-drain batteries, you need to get ones that say IMR, they are the high-drains.
AW does not make a 14650/14670 high-drain battery.

I also use an Epower, and have both the regular protected batteries, and also a 14650 high-drain battery.
A 14650 IMR high-drain is a pretty uncommon battery, and very few places sell them.
The only 2 places I know that sell 14650 high-drains are AvidVaper and Electronicstix
Heres the links:
IMR 14650 HIGH DRAIN BATTERY
AV IMR14650 3.7v High Drain Li-MN Battery - Avid Vaper
AvidVaper sells theirs for $7.99, and Electronicstix sells theirs for $8.99.

IMR batteries are not an as high mah as a regular protected battery, and both 14650 High-Drain batteries are 950mah.
I have the one from AV. It does work well in my E-Power, but keep in mind that they are a few mm shorter than the protected 14650 batteries. They do still work, but you might need to stretch the spring a tad bit (unless your E-power has the gold-plated spring in it).
What are you expecting the IMR High-Drain battery to do though? Bc its not going to put out a higher voltage compared to the protected batteries. What a high-drain battery does is just put out a more consistant voltage as the battery drains.
Like I said, the High-Drain battery I have does work well, but honestly I really dont notice a huge difference compared to the protected stock batteries.
I find that using High-Drain batteries is a lot more noticeable when used in a unregulated PV bc theres such a noticable drop in performance when using regular protected batteries. And using a High-drain battery in an unregulated PV gives a much more consistant vape.
But on a regulated PV like the E-power, there really isnt a huge difference. Honestly I find that the regular stock batteries pretty much work just as well as the high-Drain battery I have

I am pretty sure that Maast meant not 5 volts drop but 0.5 volts drop from 4.18 to 3.61 under load.

 

[Maast]

.5 volts is what I meant - the decimal point is missing.

At any rate I rather like the 1100 mah Rivas - its what I use now, I like the hotter vape they give because of the lack of regulation.

I want the high drain batteries because their voltage will not sag under load below the regulation value giving me even lower voltages.

If you try to discharge a battery faster than its design limits you get voltage sag, and from what I've read they'll sag to 3.4V or even lower. You dont see it with standard 3.0 ohm attys, but I like to use dual coil LR attys and they really hammer batteries. I go through a lot of batteries - both ego and riva, its getting expensive.

Furthermore IMR batteries will last a lot longer because they can take the higher discharge rates without being damaged. Standard Li-ion 14650 formfactor batteries shouldnt be discharged faster than 1.3 amps (ish), high drain IMR batteries can be discharged up to 4 or 5 amps without damage to the battery or voltage sag.

Thanks to the link to the AV IMR batteries, I bought 4 of them.

I still want to eliminate the regulation to give me a hotter vape using my stock of 2.0 dual coils. I'm going to order another switch and take it apart.

The reason for this is probably the switch in the E-power. It's probably a MOSFET switch with a 0.5V threshold or something. That thing limits the amount of current that can be put out, so having a high drain battery in an electrical switch which is really conservative probably doesnt do the batt justice. Thats why I abandoned the Epower, because any atty/carto under 2.0 ohms completely refuses to fire, which completely sucks since it kinda makes having a bigger battery mod pointless. 2.0 ohms is fine for higher voltages, but for the pretty meh atomizers and cartos out there, it just doesnt pull as much power as I want. So I got a mechanical mod instead, but basically I dont think high drains are really going to have much of an improvement in the e power system.

Yeah... those cheaper (less expensive) self-contained mods probably use cheaper batteries internally, not to mention all the other parts. I used to use Egos, Hello16, and epower until I realized that I was buying new batteries every few months 9which are like 20 bucks). So I just made an investment on a mechanical mod (the v3.1) and havent looked back. If the battery should die, I am only out 8 bucks, and they don't die, because the batteries are good quality. Also, it let me try 6v vaping, which is way better IMO. So much more power and versatility. The lower voltage (3.7V, 3.2V, whatever) means you need so much more current to get the same amount of power. Having a higher voltage supply solves this, so that you get less voltage sag, can run higher resistance parts (to get the same effective power), meaning everything lasts longer and doesnt get stressed as badly. just my 2 cents. Plus, if you compute it, you can get 12 watts of good clean power using a 3ohm load at 6v, whereas 3.7V with 1.5ohms, you can get 9.12W max (usually less because you're almost shorting the batteries and stressing them out). 12W on a 3 ohm coil, which has basically much more surface area due to the same material being used. The wire has a unit length resistance, 3ohms= more wire and more windings=more surface area=way more vapor and negligible heat increase, since the power is getting dissipated over a larger area. Btw, power=(voltage)^2/(resistance) or current*voltage. That should be the metric for vaping, because it's basically quantifying how much heat you are producing to vaporize the fluid
