Lets go sub ohm !!!!!

[Willf145]

Hey guys i am ready to go subohm the only thing i dont have is a multi meter , and even if i had one i wouldnt wanna carry it around all the time , is there really that much if a dropoff in preformance when using a mech? I am using vtc5s with a k101 and igo w , 1/8 air holes any help is apreciated thanks

Sorry, but with what you have said in this post you are not ready for sub-ohm.

Not ready for igo-W let alone sub ohm.

Mr.145,
Get the equipment you need and start out slowly.

Get a multimeter. You don't have to carry it around, but you do have to check the build before firing, and check the batteries before and after charging.

 

[Micchi]

Why would you need to carry a multimeter around? You need it to check resistance before you fire a new build for the first time.

Are you planning to randomly build new coils while hanging out at the park?

With a sony vtc5 on a 1.5ohm macro coil setup I am going through about 6 ml of ejuice before the battery hits 3.5 volts. Yes there is a noticeable drop off in production.

My question is , is there a noticable drop of in quality with the vtc5s and if not how am i supposed to know they are low?

And all i have asked is if there is a noticable dropoff and if not how do i tell if i am out and about

There is a noticable drop off, but, until you get the feel for it you won't know for sure if you are over discharging (possibly damaging) the battery without a way to check voltage.
You need a ohm/multi meter to test coils & monitor/measure battery condition/voltage.

1: is there a noticeable dropoff with the vtc5.
Not any different from another battery.

Got it , this is why i am asking i dont want to be one of the ignorant people who just hopes it works out i wanna do this right and safe

I think you should spend some time rebuilding on a regulated mod .
Then some time using a mech with your build.
Then try subohm.

 

[JMarca]

You know what else could cause a noticeable drop off in battery performance? A short.

Did you know that if you left a sub ohm mechanical mod in in your jeans pocket and it accidentally got stuck with the firing pin down you could lose your manhood? Building coils especially sub-ohm coils should be treated with a little respect, before you bought that mod or the atty you should have bought a multimeter or at the very least a little 20 dollar ohm reader.

Did you know that just because you build a .5 ohm coil that resistance could change over time? How would you know without an ohm reader?

Battery drop off happens very gradually while the battery discharges during use in a mechanical mod. It is so gradual that you wouldn't notice it unless you put in a fully charged battery for comparison. Over time, most of us learn from experience what a low voltage battery performs like. Until then, to prevent over-discharge of the battery during use, you should use an inline voltage indicator or digital multimeter to periodically check your battery's voltage while in use.



Discharging a battery below 3.2 volts is bad for the battery. Most batteries can not recover if allowed to drain past 2.5 volts, and will require special chargers which can revive an over-discharged battery. Investing in a top notch charger is worth the investment. Also, unless you have money to invest in a new battery every couple of days, avoid over-discharging your batteries.

All coils, especially sub-ohm coils can change resistance over time. Minute changes in tenths of an ohm can become critical to your safety with sub-ohm coils. A small ohm reader such as this one is simple to check the resistance and is also handy to make your builds on.



If you are going to be rebuilding coils, do it right & safely with the basic tools required. The above are absolutely required.

Sub-ohm coils and a battery failure is nothing to take lightly. http://www.e-cigarette-forum.com/forum/general-e-smoking-discussion/573973-what-do-case-failure.html

Honestly you need to take the time and work into mechanicals a bit slower. The questions you're asking show you have no experience with mechanicals, and no business sub-ohming.
Look man, get a mech, stop watching cloud chasing videos and learn how to use it safely building coils in the 1.0-1.4 range.
Learn what it feels like when your battery goes low. Learn how to use it safely.
Then after you've gained some experience you can start going lower on your coils.

 

[Maurice Pudlo]

As the folks above have mentioned, sure there is a noticeable point where you know its time to swap out your battery, learning that point comes from taking a vape and checking the battery, taking a vape and checking the battery, taking a vape and checking the battery, and so on till you train yourself to notice the point where a battery needs yo be changed.

Take it slow, start with coils around .8 - .6 ohms until you get then hang of it. watch some youtube videos, and meter your coils, and have fun with it!

Baditude,

Is the link you posted to the RTD digital a decent meter?

I have both the inline and an ohm reader but want a decent multimeter. I don't want to pull a second mortgage to buy one. Can you offer up a suggestion on a good modestly priced meter that will give me accurate reading....... please.

 

[Baditude]

If you have both the 510 inline voltmeter and a box ohm reader, you already have what you need to measure battery voltage and measure coil resistance. A digital multimeter will do both and more, but is not as convenient to use.

Someone more knowledgeable than I should give their opinion on digital multimeters. I know the Fluke brand is well respected as an accurate/precise DMM, but they are quite expensive.
