Found a Hybrid Dripper!

[MaNurse]

Mine is out for delivery... But gotta wait till after I get off work to play with it... Did you guys try any other 14xxx besides 14500s?

Found some 14250s haha but I doubt they'll fit.

 

[tatsuko]

I haven't. I don't have a multimeter and there is no other way to test the coil so I winged it, I'm not sure if that is really foolish :/

Yep, the hottie got me intrigued indeed!

Please get a meter. You don't need anything fancy, and I wouldn't want to call you foolish, but consider it important.

I have this mod and I really like it. It's the tiniest mod I own. I love the airflow on it, to the point that I now want to mod everything else I own to match the draw. Build quality's pretty good, though there were a couple of rough edges on mine. The button has a little too much play in it for my taste so I'll probably take it apart and see if I can tighten it up somehow. I use AW IMR 14500s in mine since that's what I've got for some of my other mods. I'm happy to answer any questions!

Looking forward to comparing it to the Precise Simplicity when mine gets here later this week.

Thanks, what meter would your recommend? I normally use my Provari to test coils. Also this is the first time I have used 14500 batteries, what ohm should the coil be for it to be safe? Thanks in advance.

I've got a Fluke 87V multimeter, but that's because I play with electronics - it's definitely overkill for e-cigs. Really anything you can get from your local electronics or hardware store will be fine, and shouldn't cost an arm and a leg.

Regarding batteries, not all batteries are created equal, so we can really only speak of them in terms of specifics. I use (and would recommend) AW IMR 14500s. As you can see from the description of those batteries, they charge up to 4.2V, shouldn't be discharged below 2.5V (I charge mine far sooner), have a 600mAH capacity and a maximum discharge rate of 4A.

Your batteries will come off the charger at 4.2V, so we'll use these two variables to calculate the lowest safe resistance to use via Ohm's law:
4.2V / 4.0A = 1.05 ohms at 16.8W

In other words: No sub-ohm setup for you on these batteries! Don't go below 1.05 ohms and make sure to leave yourself and your equipment a safe margin of error. At 1.2 ohms, you'd be drawing 3.5A @ 4.2V and wouldn't be brushing the limits of your battery. I personally enjoy the feel and flavor of anywhere between 1.2 - 1.4 ohms.

As you can see from the description of those batteries, they charge up to 4.2V, shouldn't be discharged below 2.5V (I charge mine far sooner), have a 600mAH capacity and a maximum discharge rate of 8C.

Given those specs, we can crunch some numbers to find out a few other things:
600mAH = 0.6A, and 0.6A * 8C = 4.8A maximum current draw
Your batteries will come off the charger at 4.2V, so we'll use these two variables to calculate the lowest safe resistance to use via Ohm's law:
4.2V / 4.8A = 0.875 ohms

In other words: You can push a sub-ohm setup with these batteries, but don't go below 0.875 ohms. At 1 ohm, you'd be drawing 4.2A @ 4.2V and wouldn't be brushing the limits of your battery. I personally prefer the feel and flavor of anywhere between 1.2 - 1.4 ohms.

Thanks for the info, you have a lot of knowledge. I have 14500 trustfire batteries which are 3.7V and 900MAH. Normally my coils come out at 1.9, can you tell me a bit about that set up thanks

Hey, It seems we might have conflicting information about the max continuous discharge rate of the AW IMR 14500 cells. I've seen 4A listed in a few places:

http://www.e-cigarette-forum.com/fo...ers-exporters-america-shipping-worldwide.html

Batteries & Ratings

Test of AW IMR 14500 600mAh (Red)

but in other places I've seen 8C.

I think it's something we should try to clear up - I'm not at all claiming to know which one is correct.

I agree wholeheartedly! I linked those specs from lighthound because that's where I've bought a bunch of these, so I'll shoot them an e-mail and ask for doc. I'm a paying customer, so seems reasonable enough to me.

 

[unloaded]

MaNurse, soooo what do you think?

 

[MaNurse]

Concaved deck and airy draw. I'm a over dripper... but it's a great little guy. Wasn't too hard to build. Id rather have a stiffer draw but it's actually not bad. Could make clouds with my lower nic juices. I've been doing lung hits since I got it haha. I haven't had any problems with mine not firing yet. But well see. Great little mod overall though.

Update: I sent the following email earlier today requesting more info:

Hi there,

I've bought several of these AW IMR 14500 batteries from you and I have a question about them:
AW IMR 14500 LiMN Rechargeable Lithium Battery

Your posted specs list the discharge rate at 8C, which would be 4.8A for this particular battery. I have been made aware that others who sell the AW IMR 14500 batteries list the max discharge rate at 4A. Do you know which of these is correct, and could you possibly provide me with manufacturer's documentation of that?

Thank you!

Will report back in with reply (or lack thereof).

Regarding the non-standard battery direction in this mod, I find it helpful to think of the shape of the airhole/battery vent hole: they look like the minus sign. So I put the negative end of the battery towards the minus signs. (Stupid mental tricks ....)

I also like to coil the atomizer on the side of the vent hole for the battery, so that when I put the drip shield on the airholes line up. Obviously it doesn't affect performance, but it does make it easier to notice if I've knocked it off-kilter and I think it looks a little better.

I received the following response from lighthound:

Thank you for bringing this to our attention. Our information was copied from another battery, and this error was not caught. We have made the correct changes to the site. It should have read " Max. continuous discharge rate : 4A."

Lighthound, Inc. Sales

I verified that they have changed the information on their website.

Thank you so much for your post, manglepup! I have edited my previous post to reflect the correct discharge rate and resistance calculations.

Awesome, that's really really good to know! I should have you guys know I also managed to find out that it would seem the Efest 14500 IMR batteries have a slightly better max continuous discharge and total capacity than AW IMR; the first time I've ever seen Efest IMR's out spec/perform AW IMR's. Here's the manufacturers page (I believe) - so I hope these specs are correct:

Efest IMR 14500 700mah Limn battery with Nipple (2pcs)

As noted, the max continuous discharge is 8C - which for a 700mAH capacity battery equals 5.6A max continuous discharge (.7 x 8 = 5.6). Now, I am not an expert in batteries - so if I have this wrong I would greatly appreciate anyone pointing out my error. Anyhow, here's a link to some tests which do seem to indicate some better performance as well!

IMR 14500 Batteries: Efest v AW

Of note is that the 0.5A discharge test indicated a capacity of about 640 mAH for the Efest (listed at 700) and about 560 for the AW IMR (listed at 600); which like other tests I've seen does indicate that the AW IMR's are closer to their listed specs.

The implied C rating of the AW IMR is approx. 6.6666~; against the capacity measured in that test of 560; the max continuous discharge rate is 3.73A. (6.6666 x .560 = 3.7333)

Still if we are conservative and run the C of the Efests at this total capacity rating of 625mAh; we still end up with a higher max continuous discharge rate of 5A. (.640 x 8 = 5.12A).

Thus; if we take my numbers as correct:

AW IMR 14500's are technically safe down to 1.13 OHMs (I know I'd round up to 1.2 ohms to ensure I'm not too close to the line)

Efest IMR 14500's are technically safe down to .82 OHMs (Again, I'd round up to .9 ohms to ensure I'm not too close to the line)

Now; in absolutely no way am I endorsing pushing these batteries to their line of safety - I'm only putting this out there as theoretical. Also, If any of this is wrong - PLEASE POINT IT OUT - and I will correct my post and try to stop the spread of incorrect information. I've been conservative in two places; using a measured battery test which implies a lower than listed mAh for each battery and also providing the figures that I would round up to for safety.

How's everyone getting on with theirs? I'm loving mine, it's great to take out and about.

 

[manglepup]

Loving it!

I put in a small oring on top of the one already on the switch in order to make the throw a bit longer. This thing is a beast with a micro coil.

 

[MaNurse]

Loving mine too... I'll probably try to shine up the outer parts and keep the inner tube the top cap brushed
