Agree with everyone else's comments though. A mech is a pipe bomb in your pocket if you don't build correctly or you use the wrong batteries. I strongly recommend doing a few builds using the drippers on a regulated mod before putting them on the mech.
I've never built below .15 on my drippers/mech. I know I could push the batteries further but I just don't think it's worth the risk.

I'm really looking forward to giving them both a go. Just watching some YouTube vids on building now. I have 6 x Sammy 30q 30A batteries which I will probably add 2 more of to use solely in the mechs. 30Q's are 15A continuous discharge, 30A will be the pulse rating. Always build to the continuous rating to be sure of being safe. So that being said, in a mech using these 30Q's which are 3.7V, with a 0.25ohm build I'd just be under the 15A discharge rate? Used steam engine for the first time ????

Don't 2 x 0.5ohm coils = 1ohm? I'll happily keep the rdas on my vw mods but I'm just going on what this chap had the other evening. Glad you came on here and asked the question first alexthebear , miscalculations like that can be dangerous to your health. Exactly why I am here, I've had so much support from so many people on here since I started vaping it's always my first point of call (smiles)

While i very much disagree with catface26 - i run a kayfun on a mech at high ohms - the thing you need to get to grips with is ohms, watts, volts & amps. For mechs, basically your build will directly affect the power you are going to get. You need to know the safety limits of your battery and make sure you stay within the limits. www.steam-engine.org/ is a great site for this. With the ohms law tab you can have a play with the numbers and work out what power you will be drawing on your battery. When you build your coils in your dripper, make sure you test the ohms on an ohm reader or on a regulated device to make sure you haven't got a short. The petri rda is a great rda to start with, if you are going to get some prebuilt claptons, they should fit right between the post without too much fuss. For wicking - Japanese cotton has always served me well but cotton bacon is also very good. I'd be worried if no one disagreed. Anything higher than .25 is pointless with a mech IMO. Apart from looking nice. With the amount of voltage drop you get then taking puny hits with a mech just defeats the object. 0.25 - 3.8v (assuming fully charged with heavy v drop) - just less than 60w. So what you are basically saying is that anything less than 60w is pointless? This build also exceeds our mans current batteries. Whilst I kind of get what you mean... i can't agree that you have to build super low to get a great vape, and that mechs are only for low builds, thats just plain daft to me. im not some kind of mad, high ohms preacher, i vape MTL at 14w and i have one of favourite setups built at 0.09... mechs are great at any wattage, not just super sub-ohm

So I really want to be looking for a higher capacity battery than the current ones I'm using? Any suggestions please? I don't want to be used as propaganda for the mainstream media by burning my hand on a venting battery if possible

All good opinion's guys, but the main object of the post has been achieved. The OP is now armed with the information to help make his foray into mech land a safe and pleasurable experience. Hope your gear turns up soon alexthebear.

Here is a list of recommended batteries with real tested amp limits from a wonderful chap called mooch

apologies to catface26 if you think I'm being funny... i vape mechs most of the time, most of the time at higher ohms - have done for the best part of 5 years. its just when i saw you write that 'that' was pointless... kinda got my back up a bit. cheers to different strokes for different folks

Or Sony VTC4's/5's(if genuine). Whichever you choose, if the mod feels quite warm, even after using all the calculations (Steam-Engine or your own), the build is too low, and you should stop vaping it, and recoil at a higher resistance. Mechs need to be kept scrupulously clean on all the contact points to work well. That includes the battery(s), battery contacts, 510 connection, switch, rba/atty-base, coil connections etc. Any dirty contacts cause trouble. Get some isopropyl alcohol for cleaning. They are lovely to use once set up, but take your time. Good luck.

Reading through this is quite amusing, thinking back a couple of years when I started vaping mechs were the most common thing around, vv/vw were the next stage up, my mechs were used with an Aerotank running 1.5ohm using Sammy 26F batteries, I stopped using them when I got my Vamo V5

For me, mechs are the big hitters. I usually put .25ohm builds (dual coil) in all my tanks and then if I want some bigger hits I go to my drippers. Which I build at .2 usually or a little lower if I'm feeling brave. I find mechs a bit inconvenient compared to regulated so if I'm not getting a big hit then why bother faffing around with dripping and swapping out batteries every 5 minutes.

I use mechs and regulated interchangeably. I tend to build so that the atties work well in both. Just something about a mech

norm have it running between 0.8 and 1 ohms And smaller still And me being silly 0.2 ohms I love mechs because of the size but building a set up that works well at 4 ish volts can be tricky
