Where do I get a HV atty for a 510

[beerstud]

Hello All,

I'm building a 5v mod for my 510 and it is suggested that I use a high volt atty. I can't find one and I'm not sure what I should be ordering. I'm guessing if I use my reg 510 atty at $9 buck a pop, that could get expensive.

Suggestions very much appreciated.

You don't really need HV attys for 5V though. 5V is a good voltage for standard 510s

The HV attys come in a couple different resistances. (I think) 4.2ohm and 5.2 ohm (i could be off on that) 4.2ohm is just not going to be very good at 5V (IMO). The HV attys are really for running 6V (4.x ohms) and 7.4V (5.x ohms)

Thanks, That's some good info...On a side note...Im gussing you may own a Weimaraner as myself. Zeus is 3 years old and at the rate he's going it will be another 5 years until he calms down. My 3 mile a day walks and playing ball seems to have no effect.8-o

Mine's a Dane (he just looks like a wiemar), so I have no problem with 'calm'. He's content laying around on the couch all day. He does get that occasional 'burst' (like when he comes in from being out in the rain) and then it is complete havoc for about 5 minutes.

You can see my profile pic for an idea of his size

Eastmall will not be shipping until after the 24th (Chinese New Year).

highping, I was under the impression that regular 510 attys will burn up faster with HV. I've not tried HV yet, but I do find that mine perform far better on a 14500 box mod, which is a bit higher voltage on the coil than a regular 510 batt. I have been leery of HV since I am worried about VG burning with a much higher temp, but if they are wet, this shouldn't be a problem?

Kurt, 510 attys will blow at 6V if you don't take care (keep wet, short hits, etc), but at 5V they are a lot less 'on the edge'. 5V is a really nice vape on a 510. The BB mods that use 18650's and the like are all running 4.2V anyway so 5V is not a huge leap up.

The biggest problem with 5V is that there are no 5V batteries, so the only way t get it is to use a regulator, step up DC converter, or inline resistor. All of these methods 'waste' a little of the precious batt capacity and add expense to the mod. That is why most HV mods are 6V.

I tried to send a PM with a picture of my dog, but can't figure out how to add a attachment. Looks like I can add one one this thread, apologize to all for getting off the subject.

 

[highping]

he's a cool looking dog

As far as getting off topic...it's your thread, I think you can take it OT if you want

 

[beerstud]

I order a 5V regulator for my mod, so I gather from what I'm hearing, I should be good to go with my regular 510 atty.

Cool Beans, anyway to save cost with what I have is what I'm looking for.

thxs.

the nhaler ones are 4.5 ohm

when he can keep em in stock Isaac at ikenvape also carries them

I think if you look around real hard you can also find some of the lower resistance 510s (2.2 ohm) I think standard ones are 3.2

 

[highping]

Standard 510 should be 2.5 ohm. I have been seeing some lately that are running 3.2, but they don't hit very well at all on 3.7V. The 3.2ohm attys will be a lot safer to run at 6V though. The 801, 901 and cartos all run in the high 3ohm range which is why they are all good at 6V and not so much at 3.7V.

Not true. They are probably hitting at about 3.8V tops, and that's right off the charger. A mod with a regulator should provide a consistent 5V from start to finish, something a resister cannot do. The difference in power (watts/heat) is almost double, a substantial leap up.

Umm. 'tis true. You might want to check your meter or get some new batts if you are getting 3.8 right off the charger. I re-charge mine when they get down to 3.8V (and that's after a couple days in my Chuck)

Although I do agree with you on the consistency of using a regulator. I would never suggest or recommend using a resistor, that was just one of the ways I listed that it would be possible to get 5V from the 3V and 3.7V batts that exist.
And I can say from experience, that it is not a huge step up between a 510 running 3.7V(err 4.2V) on an 18650 in my Chuck and a 510 running 5V on my 50Watt variable voltage desktop power supply.

I guess I wasn't clear enough. I meant vaping (under load) right off the charger. Yes they come off the charger at 4.2V (not under load) but as soon as you attach an atty and vape they are down to 3.8V ish.

On another forum I asked someone with a fancy, expensive meter to do some tests.

Ok, couldn't wait had to do a couple of voltage checks.
The meter is a 5 1/2 digit HP3478A, still in calibration, and it checks in spec on my 10 volt and 10 ohm standards.

The following batteries were charged then allowed to sit for about an hour off the charger before testing: a 3000mah 18650, a 900mah 14500, and the battery cell removed from a disposable 510. A Titan labeled gold band 510 atty was used for a load test. The resistance of the atty, cold was 2.1748 ohms. I think this is the lowest resistance atty I have right now.

- 18650 unloaded voltage 4.211 V, loaded (3 seconds) 3.889 V

- 14500 unloaded voltage 4.208 V, loaded (3 seconds) 3.831 V

- disposable 510 cell 4.113 V, loaded (3 seconds) 3.701 V

Only one 3 second load test per battery and the atty was allowed to cool between tests
I'll test some more this weekend (for real) but I have to get up early.

I'm not trying to nitpic, but plunking in the values to determine WATTs based on a 2.2 ohm atty:

3.8V (18650) = 6.6W
5V = 11.3W

That's a big jump.

Gotcha. Thanks, that's great info. Makes total sense.
