mech mod dummy question

[clivealive1]

right i have only used varable mods vamo and MVP2 and dont quite get the mech mods.
 I understand that they are not varable but dont get how it works.
 I also understand that i need to use a protected battery.

what iam looking for:

I want around 7.5 - 8 watts (generally what i vape at on varables)
I want or assume I want a 18650 battery or at least one that will last an age.
must take iclear30 and iclear30s 's.

so what do i need?
how does it work


cheers

Hi there @clivealive1i also asked this question earlier on today and got some very informative answers,look for a thread on the first page called hmmm mech mods as this is what I asked,hope it helps

Maybe take a peek at the innokin coolfire1 &2 they run at a constant 8.5watt and are pretty snazzy bits of kit by the looks of them. A mech mod runs at 3.0 or 3.2 volts I think always, to get them vw summink like a nemesis clome and a kick module which you can put into the mech mod to turn it to vw, you can then set it to run at the voltage you like pretty easy, goto fasttech for both a bargain and youtube to understand what the kick module is all about, just type in sigelei kick or evolve kick and if will click after watching a video

clivealive1 here's aaront903's thread allaboute-cigarettes.proboards.com/thread/34527/hmmm-mech-mods?page=1&scrollTo=606009

thanks both of u

Thanks Phoenixflame (Julie) I didn't know how to link it lol

scaffman69 and clivealive1 , a mech runs at what the battery outputs at the time. A fully charged battery will be about 4.2v but drop to about 3.7 for most of its discharge. Once it goes below that you should feel a drop off in performance and get the battery back on charge.

You might not get that voltage under load due to conductivity of the mod and the battery's ability to keep up with the load. It is unregulated.

Didn't read the other thread, but you can work out the wattage you will get by using this ohms law calculator - theecigstop.com/ecal.htm - assume the battery is 3.7v, you just need to put in the resistance of the iclears coil, which wouldn't be less than 1.6 ohms i imagine - as it happens, a 1.6 ohm coil at 3.7v is about 8.5W but if the coil is 2.4 ohms, you get only 5.7W. Mechs are great, but need lower ohm atty's to make the most of them, otherwise a regulated mod is better - or you can use a kick as mentioned (but I'm a purist - couldn't kick a mod)

If you do fancy a mech, it's good to spend a while with regulated mods and experimenting with different voltages or wattages so you can recognise how they feel before going to a mech as you don't have any protection against over discharging your battery too far. You don't use protected batteries in a mech. It is up to you to protect yourself and your kit.

Really?

That's right the consensus is to use safer chemistry batteries rather than protected lithium ion. Because IIRC the protection is not perfect and the consequences of a battery going bad are worse for lithium ion than for safer IMR + Hybrid batteries: the former are more likely to explode, vent at a much higher rate and once they start they go into a vicious cycle. No manufactures bother to put protection on safer chemistry batteries as they don't feel its required.

You have no reason to buy a mech mod other than the look of the thing. Your electronic mods will deliver 7.5 - 8 watts more consistently and more safely.

[clivealive1]

thanks all
brilliant details, i wrongly assumes u use protected batteries as they said that u can get shocks etc. now i get it. I think lol (so IMR it is)
couldnt get the link - theecigstop.com/ecal.htm to work, looked on site and got some good info, but couldnt find calculator.

found one here very useful
ohm law

I know all of that and only use IMR batteries myself as they are indeed reckoned to be safer than ICR batteries ...  however it is wrong to tell someone not use protected batteries in a mech mod  ...  if anything he should have advised not to use unprotected ICR batteries  ... his statement might lead someone (like the OP clivealive1 ), who wasn't aware of IMR safe chemistry batteries, to use unprotected ICR batteries which offer no protection at all. If you don't have or can't afford IMR batteries then protected ICR is the next best choice.

You can get higher wattages with mech mods though by using lower ohms coils, thats where the real advantages come in, along with more dangers though so read up!

Mines currently running a single coil at 1.1 ohms which gives about 16 watts when battery running full charge.
But had dual coil giving 0.7 ohms which gave 26 watts (providing battery giving out 4.3v, but reading about maybe they only give 4.2v)

For this you need a good battery, mine has 10amps discharge limit so 0.7 ohms is approaching its limt, can't find link to work this out now though.
You can get batteries which allow 30amp discharge to allow for lower ohms too.

[clivealive1]

doesnt 16 or 26 watts fry the juice then.

A 0.7 ohm coil at 4.2 volts will draw 6 amps (current = volts/resistance)
