question regarding mod design.

[bullet08]

most mods i have seen on the FT has no insulation around the bottom contact. how does it prevent the battery from shorting out? i see top cap has contact that can be adjusted for battery rattle, and bottom can has contact that can be adjusted for the button throw.. but what's to prevent from the bottom contact making contact with the battery to shot the whole setup? are they counting on the battery wrapper to hold the battery in place until the button is pressed to make contact?

I've never bought a FT mod clone, but there can't be any contact until the switch is pressed or it won't work. So the battery must be sitting in the open area.

An authentic mod with insulation on the switch wouldn't work if the battery had no wrapper either... it would probably short just by the sides of it touching the tube.

Yes, there are numerous mechanical mods both clone and authentic that rely on the battery wrapper to insulate the negative connection, this isn't really an unsafe practice it just necessitates checking the battery wrapper before you insert it into said mod. One of my most used mods is the SMPL by Epic Design Studio and it does not have a negative insulator, it has never auto fired and never will because I check my batteries every time I put one in.

i can see where this can turn into daily routine.. checking battery, cleaning atty, checking wick.. reloading the juice.. wiping out the setup so it won't look too grungy.. and keep looking for new toys to play with..

 

[Peter Veneziano]

Disagree. It can become unsafe. The outside case of any good mechanical should be negative. Even if the batt wrap was damaged, or was destroyed in thermal run away, there would be no more chance of shorts, as the outside of the batt is negative.

If mods are being built with the case as positive, I wouldn't buy it, much less go near someone even using it. I tend to stay away from people using lith ion's as it is for that matter. I wouldn't roll the dice on a thin piece of plastic wrap, even if you did look at it good before inserting.

Imho, you build things that physically cannot become a problem. On top of that, there is zero reason not to use the proper fuse in these. Then you don't worry about it if all the other variables happen, like wrap damage or thermal run away. You don't bet on those things not happening, because they can.

No wonder 100+ years later planes still crash. People.

so the idea is battery holder is negative, and insulated from positive contact. if that's the case, putting on the atty with resistor will fire them up. so, how is the battery in suspended without rattle and not in contact with switch? how is it being suspended with out rattle?

Well my first recommendation is just.. Don't buy anything from FT. It's really hit and miss, it takes forever to ship, and on the whole, you're potentially sacrificing your safety for a small amount of $$.

Quality clones exist, and they're not being sold on FT.

 

[bullet08]

from what i have seen, China seems to have few mass manufacturing facilities. each brand will get their product from there and put brand boxes on them. FT is just a reseller. if you know what you are looking for, and bit with luck, good mod clone can be had for less than half the price that is going for here. of course, if you are in hurry, that might not work.

it's not just clones that i have seen, some authentic mods do not have insulation between bottom of the battery and the negative contact. i'm just curios how that works.

How many times have you ordered from FT and what did you order?

Because 80% of your above statement is wildly inaccurate.

Once. My order took TWO MONTHS to arrive, and when it did, I wasn't happy with my product. As it is, my FT Nimbus still goes unused. Also, the top cap doesn't fit on my other Nimbus clone! And yes, they're both "XL" clones.

I realize they're a reseller, so they can't necessarily "be blamed", but their low price point is there for a reason. None of these products are quality controlled, and "you get what you paid for" doesn't even apply, because other vendors QC their stuff and still manage to keep the price point low.

I am not a fan, in case you couldn't tell.

Also, worth mentioning, by the time my order had arrived, I had purchased entirely new vape gear and was banking on the notion that my FT order would NEVER arrive. When it finally did, I was surprised (and disappointed) when comparing the FT gear to the gear I had gotten in the meantime.

What was in the order, did it contain batteries?

If your order was under $15, did you pay the extra few pennies to upgrade the shipping(a must do ALWAYS)?

In 11 personal orders, i've never waited longer than 16 days from when it left FT's hands, the long ship times are almost always batteries or non-upgraded 'slow boat' shipping.

There are basically zero quality controls on any clones, and most domestic vendors are buying from the exact same factories/distributors as FT, its always a crapshoot.

I wouldn't ever expect clones parts to be interchangeable unless it has already been confirmed, but again that has nothing to do with FT itself.

Minus the idiots and crazy people, the FT discussions are a good way to get insight into a product/build quality/possible issues when trying to determine what to buy.

I dont know of any mech mod that has the interior side walls insulated. They might make them though.... It all comes down to the user checking their batteries for damage. Too many people want plug and play devices which mechs are not. They require a lot of battery knowledge. I have been using mechs for quite awhile and always check my batteries. A fuse is a good idea but is not necessary to use mech. A fuse wont help you out, if its a sidewall short anyway.

...what are you even talking about because NOBODY here even mentioned the outside case being positive. Fuses are junk as well, anyone who is using a fuse in a mechanical mod should seriously consider never owning a mech if they're that paranoid about safety.

so the idea is battery holder is negative, and insulated from positive contact. if that's the case, putting on the atty with resistor will fire them up. so, how is the battery in suspended without rattle and not in contact with switch? how is it being suspended with out rattle?

No, the battery holder is in fact negative but the battery wrap would be insulating it from negative contact along the outside edges until the button is pushed which touches the unprotected center of the negative and completes the circuit.

Well my first recommendation is just.. Don't buy anything from FT. It's really hit and miss, it takes forever to ship, and on the whole, you're potentially sacrificing your safety for a small amount of $$.

This is entirely wrong, I have FT clones that outperform the originals. Read the reviews and buy things that are in stock and you'll be happier, but feel free to not buy from FT anyway...all the more for me!

it's not just clones that i have seen, some authentic mods do not have insulation between bottom of the battery and the negative contact. i'm just curios how that works.

The battery wrapper outer edge is what insulates the negative contact around the rim where there is no insulator, when the button is pushed it completes the circuit to the center of the battery negative. There isn't much to understand here, you either get it or you don't.

 

[bullet08]

that answers my question. it seems bottom cap catches the battery along with top pin to hold the battery in place. the negative pin doesn't come in contact until it's fired. seems like there can be a better design.

 

[Peter Veneziano]

Fuses are junk

 

[Froth]

Have you seen a fuse melt and hard short a mod? I have. These "foolproof" fuses are made in mass quantities and not every single one of them is quality checked, only a few of each batch is. I push over 100W on five mechanical devices EVERY day, I've never used a fuse and have never had a single issue.

It takes a little bit of "smart" to use a mech mod safely...If you rely on something else(Like a $5 fuse) to be smart for you then you're not actually being cautious at all, you're letting your guard down because you think the fuse will be the "end all be all" failsafe. But what do I know, I just work with high amp electrical loads every single day of the week for a living...

Mechs are nothing fancy just a battery,510 connection, and switch. They are a simple design and some are easily repairable with a trip to a hardware store. Maintenance is vital to any mech because there is no safety features. Its doesnt take an engineering degree to use a mech but you have to understand your batteries,ohms law and use a digital multi-meter.

Dont I see any mech mod maker really changing the design from what we have present day. Some will make fancier switches or hybrid connections for attys' but the tube will stay the same.

As for fuses....Froth is right!!! Most are junk i wouldnt waste my money on a fuse, BUT i would buy a Kick2 by Elvolv. I use a Kick2 for carto tanks and when I loan one of mechs to friends when their gear goes down.

 

[cammelspit]

I'm new to mechs in general but there are MANY smart ppl here on ECF that are MORE than willing to help out. I now know more about battery chemistry then most ever will and more that I ever thought anyone really should and now I know I can vape safely. Even with the boom to the E-cig/vaping industry world wide the whole thing is still kind of new. Tobacco was used be Europeans as far back as mid 1400s and even earlier in the Americas by the indigenous peoples. So, being only what, a few decades old? You are pretty much responsible for your own safety.

Just thought i'd chime in
