Mech Mod help please...

[Thevapourtrail]

Hello,

Been vaping a while on my MVP v2, various tanks an magma rda.
brought a mech (see pic below) with an efest 18650 2500mah. First of all is this battery unprotected like it says which iv read never to use on a mech? Or does this not matter because its "safer chemistry" whatever that means?. So i Charged it up an it went to 4.29v? Is this normal? Then my bad didnt realise how fast a dual coil .6 build used it so few hours later im at 3.2v, charged it up on fast charge (1A) an went back to 4.29v in around 40mins?
And finally i want to go back to single coil, can i run a mech on 1.2ohm or say even 1.8ohm build/tank or is it just going to blow the coil or taste burnt at 4.2v? I suppose i want to know if they are best kept to just sub ohm builds?

I know there are alot of questions and i have read thru quite alot of contradicting text, im still learning and reading new things every night now. If someone in the know could take time to answer these id feel alot safer as the internet does a good job of making me fear for my life! Cigarettes seem alot less life threatening at the moment!

I can't open the image so I can't really comment on the battery(sounds like its a 20 amp efest which I would feel safe with unless I was doing super sub ohm)
As for single vs dual coil, it's just preference. I like .3 - .5 ohm dual coils but I build 1.6 ohm singles for my wife. You shouldn't run into any trouble with it at all. However, your batteries charging up to 4.29 volts seems a little high to me. Maybe someone else has more info about efest batteries

There might be something wrong with your charger. 4.29 volts is too high. It should never be above 4.25 V, preferably closer to 4.20 V. Overcharging is not good for the battery.

A 1.8 ohm coil should be fine on a mech.

Yes, IMR batteries are "safer chemistry", and you can use them in a mech.

If you are new to mech mods and/or rebuildables I highly recommend you spend some time with Baditude (our resident battery expert) and visit his blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.

Baditudes Blogs. The blogs regarding mods and rebuildables are listed below:

Hello,

Been vaping a while on my MVP v2, various tanks an magma rda.
brought a mech (see pic below) with an efest 18650 2500mah. First of all is this battery unprotected like it says which iv read never to use on a mech? Or does this not matter because its "safer chemistry" whatever that means?.

I think that's the purple battery rated 20 amps continuous like this one, correct? If so, it's an unprotected hybrid lithium ion battery and it's pretty safe. Safer than a protected ICR lithium ion battery. If you go to Baditude's blogs from Susan's link and read about batteries you'll find out all about the different types.

BTW, I would not go less than 0.3 ohms with that battery.

So i Charged it up an it went to 4.29v? Is this normal?

No. As Dampmaskin said, 4.25v is the most a battery should ever charge to and even that will reduce batt life compared to the 4.2v it should be going up to. Charge to 4.3v all the time and their life will be quite a bit shorter.

Then my bad didnt realise how fast a dual coil .6 build used it so few hours later im at 3.2v, charged it up on fast charge (1A) an went back to 4.29v in around 40mins?

Hmm, a 0.6 ohm build taking your fully charged battery down to 3.2v in three hours means you chain vaped really heavily. At 3.2v your battery was pretty close to empty so it would take at least 2 hours to charge it at 1A and probably closer to 3 hours. Something is wrong here and I suspect it's your charger. What charger is it? Do you have a DMM or are you using something else to check battery volts?

And finally i want to go back to single coil, can i run a mech on 1.2ohm or say even 1.8ohm build/tank or is it just going to blow the coil or taste burnt at 4.2v? I suppose i want to know if they are best kept to just sub ohm builds?

With the Magma on a mech mod, a full size RDA, a 1.2 ohm single coil build will probably not make much vapor. I would suggest you take it down to around 0.8 ohms to start with and see how that goes. That will be more in line with what you've been getting with the 0.6 ohm dual coil build. A 1.8 ohm single coil build is not going to vape well at all.

I don't suggest you use a single coil tank (a clearo) on a mech mod. You'll do better with dual coil tanks. Carto tanks at around 1.5 ohms will be much better IMO. They have a greater range of power they vape well at than clearos so they will handle the voltage drop much better. OTOH, if you experiment with it and find something that works for you, that's all that matters.

Honestly, if you're going to be vaping above 1Ω you're better off using your MVP. It's regulated, so you'll get a consistent vape from full charge to about dead... Plus you're not running any of the risks that come with mechs (accidental firing, over-discharging battery, etc.) and you'll have more power available for your single coil RBA's that can handle it.

You're gonna want to get a new charger ASAP. Overcharging your batteries like that (even by .09v) can cause major issues. Aside from degrading your batteries' life and integrity, you're also running the risk of it venting or catching fire while charging or discharging.

Also, you should not be using a mechanical mod at all if you don't understand battery safety & ohms law as it pertains to vaping. Doing so is a major safety risk, especially if you don't know the amp rating on the batteries you're using. Not trying to sound condescending, it's really not complicated, but it can be potentially dangerous and is something anyone using mechanical mods should know. Kinda like you don't drive a car until you know the rules of road safety... You don't vape with a mech until you know the rules for battery safety

 

[Quick1]

I've been out of touch for a couple of years here. My 4 year old genesis prototypes have sort of given up (like the 510 connector threads wore out but the connector is set in the base in a block of epoxy... stuff like that) so I'm back.

Why are some advising that you need a mech for sub-ohm? I just looked at the provari and it appears they have it limited at 20A? I'm probably going to be trying out dual coils at 1.6ohm each for about .8ohm total. At 4.2V that's going to be about 5.25A and well within the provari's limits? Wouldn't the provari work until you start getting down to 0.3 ohms or less? I must be missing something.

[Edit] whoops, guess I did miss something.

Version 2 now has a higher amperage limit of 3.5amp for low resistance atomizers and cartomizers.

....never mind
