First mech mod

[GingerNinja]

I've recently picked up my first mech mod, a Coilart Mage Mech. Stunning looking mod, and feels very weighty in the hand.

I've only taken around 10 puffs on it since I've got it though, as I've got a couple of questions regarding mech mods, despite doing what I thought was plenty of research before hand.

I've currently got - 2x Samsung 25R (green) batteries - 3.6v, 20amp, 2500mAh & 2x LG HG2 (brown) batteries - 3.6v 20amp, 3000mAh.

With the Samsung & LG batteries am I right in my calculations (steam engine website) that the coils I should be using should be no lower than 0.3ohms? And if I changed over to Sony VCT5 (3.6v, 30amp, 2500mAh) the coils should be no lower than 0.2ohms?

If the above is true (unless I've got it all completely wrong, that would roughly equate to the following coils;

Samsung & LG -Ni80 28awg with 6/7 wraps
Sony - Ni80 26awg with 6/7 wraps

The main reason for all the questions is that the mod came with some handmade coils, made with Flatwire FlatSixy 22g wire. And these are reading 0.13ohms on my Vaporesso Revenger mod, which I think means they are to low to use in the mech mod with the batteries I have at present. At least if I want to stay on the safe side of things.

Is the general rule of thumb with mech mods, at least from a safety perspective, to go no lower than 0.2ohms on the coils?

Any help and advice would be greatly appreciated.

This is why I'm avoiding mech mods thus far. I've read that rules are different for regulated and unregulated mods.

Tell me about it! That's why I'm making sure I go about things the right way, and trying to stay on the safe side of things. Although I do understand that there's always a certain level of risk with mech mods if you aren't careful.

But yes you're pretty much bang on

Spot on with the calculations so nice one. If only more folk took that kindae time I'd no need to go to the brown trousers every time I saw a thread with the title 'first mech'.

With VTC5a's or the pink LG HB6's yes you can build a bit lower res coils. And, generally aye, 0.2 is about the bare minimum to build to.

However.....

And I'd not recommend this with your current cells!!
You can go lower.
AS LONG as you know the resistance of the build AND you have the right batteries. Again, VTC5A or the LG HB6's.
When/if you go for better cells, then the flatwire will be fine enough to go in the atty. Again, check the resistance before firing and don't do any fiddling/adjusting of the coils on the mech, use a regulated gadget to get them glowing all nicely.

Oh, one last thing that I'm sure you know fine well, make sure you are regularly checking the switch, 510 threads and pins and the tube for any signs of iffiness and keeping all the threads shipshape and shiny.

I'll order some of the Sony VTC5A's then just to be on the safer side of things

Check Fogstar & 18650uk, both recommended vendors on here & very helpful if you have any queries.

Went with 18650uk in the end, cheers for the heads up

Other than batteries and resistance, which was covered above, about the only other thing I can think of is to keep the coils simple on a mech, whether it's SS, Nichrome or whatever, flatwire roundwire etc, the meatier the coil the longer the ramp up, leading to batteries heating up.

With @EmbraSewerRat guidance I changed from SS to Nichrome, giving me more wraps to play with to adjust resistance, quick ramp up times and cooler batteries.

Jeez don't tell @Ben fogstar he'll be crying in his next coffee bought to him by his minnions
