Stepping up to mech?

Hello, long time no see!

A couple of months back I purchased my first vv/vw mod and RDA and I am pretty satisfied with it. But I feel like I want to step it all up.
I'm really curious about increasing the wattage beyond my SVDs max 15W and perhaps even lower my coils resistance below 0,9 ohms.
However I'm not sure if I'm ready to jump into the mechanical mods and the variable ones that can handle low resistance and high wattage such as the eVic Supreme is a bit above my budget.

I have been looking on mechanical clones by Hcigar such as King and Nemesis SS and also a Chi You clone which from what I have read keeps a high quality.
If I decide to go with one of those mechanical mods will me and my build be safe if I make sure that the ampere is below my batteries maximum of 10A (AW IMR 18650 2000mAh)?
And also I haven't quiet understood how the wattage of a mech mod is determined. I mean I can easily figure out my coils resistance by reading it off my SVD but from there I would be kind of lost.
Lets say I have my battery fully loaded and is at 4.2V and I build a coil at 1 ohm. 4,2^2=17,64watt, is that it and if so how would I keep track of the batteries voltage while using it in a mech?


Appreciate any help and opinions.:)

First off, if you do make the jump, try to get a little better versed by reading more info on the forums... This is a good start though... At least you asked!

Second off, don't rely on your SVD to get your resistance.... Get a good meter to do so...

As for wattage... That's easy.... Your battery freshly charged will be 4.2 volt.... Voltage ^2 / Resistance = wattage... So 4.2^2 = 17.64... Let's say you have a .9 ohm coil... 17.64 / .9 = 19.6 watts.... As for amp draw on the battery... Voltage / Resistance = amps... so 4.2 / .9 = 4.67 Amps which is within a 10A limit...

Does that make sense?

I will certainly make sure to learn more about mechs and safety before I purchase one.
So the wattage will just lower as you use the mod? Getting more complicated without that little LED screen telling you all the info..

Also, are those "safety bricks" necessary? For example one I'm looking at is labeled at 7A. So basicly if I would miscalculate something and the circuit exceeds 7A it will cut the circuit and protect the equipment from.. melting?

Thanks a lot!

there are some really important factors that come into play and required items

required items
Ohm meter
volt meter
quality batteries
quality charger

The reason for a dedicated ohm meter is you will have a much more reliable read out to the second decimal place. The reason for a volt meter is so you can check your batteries voltage.

You seem to be on the right track by looking for information first so keep doing that and never stop learning.

Your calculation of watts is correct but the more important calculation is amp draw (voltage / resistance) = amps so 4.2/1=4.2 amps or 4.2/0.5 =8.4 amps
As you can see you will quickly reach amp limits of a 10 amp battery. You should look into the higher amp limit batteries for a bigger safety window in my opinion.

Never go near the amp limit of the battery always leave room for cushion in my opinion. ( I tend to stick around 50% of the limit )

As far as checking the voltage of the battery pull it out and check often in the beginning. After a few days you will know how much liquid you will go through in a full charge.

There will be much better information than what I wrote coming shortly from people that know more than me so read that also

The most important thing is safety In my opinion you should not do this until you are 100% sure that you are going to be safe.


Good luck and be safe

You keep track of the battery voltage by using a multimeter (or volt meter). You can also get an idea by the change in the performance of your coil (vapour production).
It is recommended that you recharge your battery when it gets to around 3.6V.

The best way to be safe if to get a decent ohm meter (one with two decimal places), along with this it is helpful to have an ohms law calculator (so that you don't have to calculate by hand), a good one is Vaper's toolbox on android.

A better battery to get is the sony VTC5 (or 4, but 4 has less mAh), it will allow you to go lower ohms if/when you need to.

I am using a 10A limit battery on my mech and it is stopping me from experimenting with builds and lower AWG wire.

Thanks for all the helpfull information. I will most likely start off with my current battery and pick up the mentioned VTC5 if I feel that I'm in need of it later on. I will not overextend on my battery, safety comes first.

I will make sure to pick up a reliable volt and ohm reader as it seems way more flexible than using my multimeter.

I have to say that I'm really tempted to order a Hcigar Nemesis SS along with a RBA as the only rebuildable atomizer I got now is an RDA.

Mechs are small and pretty, but if you don't mind boxes, try the ipv2 I read somewhere there's a coupon code to get it for about 65 bucks, not sure the site. A google search could tell you though. Regulated 50 watts, with protection built in. Pretty wild sauce my friend, wild sauce.

It is the best vape you will ever have( idk about the vv/vw boxes, because I dont have one, they dont appeal to me)
I use the sony vtc4 30a 18560s.

I like agamers battery safety policy( 50% of the batterys rated amps) I follow the same rule and never go below a .3 coil build.
actually .3 @ 4.2v is 14amps and 58watts.

I see no need to ever go below .3, the vapor production is phenominal, and your batteries wont get mad, even at lesser voltage( 3.7-4.1) it is still an excellent vape
I can guage my voltage pretty well now without using my meter on my batteries, I take them out and they are 3.6 to 3.7 every time now

It is easy to do correctly, you just need to be more aware and pay more attention.
