Im looking at a few sorted mechs and i have a protank 3 with .8 ohm coils. Do ohms matter on a mech? I know a regulated box only is stable through certain ohms. Is this the same on a mechanical?
Does ohm resistance matter on a mech?

If anything, ohms matter far more on a mech than on a regulated mod. On a regulated mod, you'll likely burn out the chip before you do damage to your battery -- in most scenarios the device simply won't fire any resistance that it isn't capable of handling. Additionally, a regulated mod will be much more suited to run a ProTank. With a mech mod, as the battery voltage drops, that's less voltage applied to the atomizer. The max voltage 18650's output is 4.2V, so that's the most you'll be getting out of your mech mod + your ProTank. If you use a regulated mod and know you prefer a higher voltage (4.2+) for a specific atomizer, you're pretty much SOOL, and you'll never be able to attain that same experience on a mech mod.
On a mech, there is no chip. The voltage of your battery is the voltage you output. If you abuse your battery to the point of thermal runway in a mech, congratulations! You've made a crude pipe bomb. This can be done by creating a short in the top cap, or building too low of a resistance, or having your mod auto-fire, etc... You need to be aware of quite a few safety precautions before you begin using mech mods. With most regulated mods, there are safety features in place to prevent you from creating a pipe bomb scenario. Whether that's displaying a "LOW ATOMIZER" message on the display, or "ATTY SHORT", or even "CHECK ATOMIZER" -- it can save a LOT of time, and potentially, some physical harm.
Read up on battery safety before you even think of picking up a mechanical mod, whether you're using pre-built coils or building your own.

Please
Read up on battery safety before you even think of picking up a mechanical mod, whether you're using pre-built coils or building your own. You really should understand this before getting into mechs!

Yes they do. Determines the amps being drawn from the battery and the watts the battery will put out to the coil.
Ohms pretty much ONLY matter much on a mech. With a regulated mod it either works or don't. On a mech it can work but blow up in yer face if things are not right.
.8 ohms on a mech...
What size batteries are you running? .8 ohms won't be a problem on a mech as long as the CDR of the battery is 10 amps or higher. NOT THE MAX PULSE RATING, but the CDR (Continuous discharge rate).
At .8 ohms, you'll be drawing 5.25 amps at full charge, and less as it drains.
For 18350, the only batts I would consider safe are the NEW AW IMR 18350 800 mAh 12amp CDR. The older ones are only 6 amp, and thats not enough safety margin
For 18500, there are quite a few rated 10amp CDR or better.
For 18650, most of those are rated 10amp or higher, but make sure.
.8 ohms is not extreme by any measure, but you DO want to verify that your battery isn't being taxed by it.

Why can't I get big clouds with my mechanical mod?

There are a lot of 18650's on the market. Some have very low amp limits.
Specifically what brand/model battery is it, and where did you buy it?
@Mooch is our resident battery expert and he has a TREMENDOUS guide to 18650 battery capabilities here:
18650 Safety Grades -- Picking a Safe Battery to Vape With | E-Cigarette Forum
If you scroll to the top, there is a list of mfg's & models. EVERY 18650 on that list is safe down to .4 ohms. As long as your battery is on that list, you're good to go my man!

safety will depend on what 18650 you are running in the mech cant say for sure if .8 is safe with your battery if we dont know what battery you are using pics of the battery will help if possible and ohms will affect flavor and vapor production for sure.
Crude pipe bomb? Please, 18650 batteries are nothing compared to pipe bombs. LIPO setups are pipe bombs. The amount of gasses produced during a lipo failure is ridiculously large w/o a protective covering ( just aluminum pouch showing ).. Bought myself a smoke detector for my room so i don't die, haha.
All I can say is I ran an old sony sf us18650gr with a .8-.9 coil for almost a year no issues and that is after taking it out of a ibook g4 its only rated for 5amps. Don't ever go lower than 1ohm if you don't know your specific battery. There are other batteries that are poorly made that can vent, blow up is kind of extreme but get hot, burn you, and really freak you out that's more realistic. I was a marine from 2003 until 2012 and I can say I've felt with fuses that are far scarier. I have also vented quite a few 18650s for the fun of watching and have been diy engineering my own vaping stuff for 3 years. I have just now bought my first mod I didn't make so best advice BE CAREFULL and have fun.
Don't do it Bro! It says "replacement for Sony VTC3 VTC4", and they are slyly not showing any branding on that wrapper. Those sony's are some of the most often counterfeited (and by that I mean buying reject batteries and wrapping them in the same color wrapper) and from the looks of that ad, those would seem likely counterfeit. At that price, they're not much of a deal anyway.
on the page linked below, it clearly states "If the label says ICR, TrustFire, UltraFire or doesn't really say anything identifiable, don't use it. The risk isn't worth it."

Here is where i recently bought mine. Genuine LG HE4 2500mAh 20a CDR. 4 for $20 shipped, and they come with protective cases:
Ebay Trusted Seller
If you HAVE to have the extra 5amps protection of a VTC4, for the cost of 400mAh (shorter life before recharge) you can get them here:

@Thunderagevapekid Please, do not get a mechanical device just quite yet.
There are many viable options out there concerning regulated mods, where you can learn from watching the screen, it really helps the entire process. What you see the screen showing you , can then be cross referenced on ECF by reading, and discussing options.
Were working with powers that have the ability to change our lives, for the better if we choose. This, we cannot afford to make the mistake of jumping in early.

YES... most definately... before you even want to think about messin with a mech, at least try to understand Ohms law or else use some type of app to design coils properly.... and GET an Ohm meter to test your builds before even letting them near your mod....
