Today I went out and got new Clapton coils for my ar15 mechanical mod. And some cotton, when I got home I put it all together and it would not hit like it did before I got the Clapton coils. It produces very little vapor like it's not heating it up enough. I was thinking maybe the batteries were weak or bad. I'm using ultralite 18650 4200maH 4.7V li-ion batteries. They worked fine before with just a normal 22 gauge build but the second I switched to Clapton it's not firing hard enough. I' just wondering what the problem could be and what batteries to use to make it hit like it should. Thanks for everyone' input

What Ohms reading are you getting for your clapton build?

I'm sceptical that your batteries are 4200mah as I've never heard of a vape safe 18650 that has more than 3000mah. What's the CDR of those batteries?

If the CDR is less than 20amps they are probably not safe for use in a Mech Mod. Even then it depends on the resistance of your build (Ohms).

If you can't answer any of the above I'd advise you stop using your Mech mod.

Edit : also I've never heard of a 4.7v 18650. All in all this is not adding up.

What are you using to measure the resistance of the coil(s)?

Where did you buy the batteries and why did you choose them?

Have you calculated the amp draw of your atomizer build?

What was it?

If you can't answer these questions, you need to put down that pipe bomb.

You've got two problems:

Firstly those batteries are garbage rewraps totally unsuited to vaping, let alone low resistance mechanical builds
I've never heard of Ultralite but based on the name and the claimed mAh they are capable of 4-8 amps at best, probably far less.
You are over stressing them beyond their capability and they are sagging and failing to deliver the power requirements you are making of them. Until I know what the resistance is of both the 22G and the Clapton builds I cannot advise you of what batteries to use that will do the job.

Secondly 22G is pretty heavy wire that will take a lot of power to heat up. If the claptons have a greater mass (more wire) which seems to be the case, then they will require even more power to heat them up. If you understand how mechs work you will realise this means using an even lower resistance, which means greater load on the batteries exponentially increasing the importance of them being suitable in terms of quality and amp limit.

Single battery mechs are not really suited to high wattage vaping on large high mass coils. It can be done, but it's ill-advised even if you really know what you are doing.

I know it sounds dramatic, but do not use that setup until we have you sorted out. Your battery may explode and injure you.

I am in agreement with what has been stated above. You should check this out for battery recommendations and suppliers in order to find a new, safer set of batteries: Mooch's blog | E-Cigarette Forum Check out the newest chart for batteries that will be safe for you, and approved suppliers are listed at the bottom.

Likely, your build is unsuited to your batteries but before you do ANYTHING you need to also let us know the resistance of your build (from an Ohm's reader, since it's a mech) and it could be the resistance is too low, or there is too much metal in your build.

With that said, you really are going to need to do your homework if you want to build successfully. There is some good information in the Coil Builds and some of the threads are really helpful, but you can also ask questions there.

I am not certain you are ready for a mechanical mod (yet). You can certainly get there but you really need to understand safe battery practices, how to build coils safely for your mech, Ohms law and a host of other things. Please don't use your mech until you have fully informed yourself. Please don't think anyone is patronizing you either, mechs are difficult to work with and understanding the safety BEHIND mechs is really necessary to vape one safely under ALL circumstances, not just happening on an build and battery that "work." If your battery gets overstressed (and it will) it could vent catastrophically.

Good luck,

Ever seen someone plug in like Four 3-Way Converters to wall outlet, and then like 12 power cords? What Happens?

You Trip a Breaker, Right? Because you are Drawing Too Many Amps.

Now say there is No Breaker. What Happens? The Outlet Gets Hot and you might Burn your House Down. Think of your Mech Mod just like that Wall Outlet without a Breaker.

Only when you Draw Too Many Amps on a Mech Mod, it Doesn't Burn your house down. It causes the Battery in your Mech to Fail. Which just might Cause you Mech Mod to Explode. And there is a Very Good Chance that you will be Sucking On one end of it when it does.

Put that Mech in a Drawer and buy yourself a nice Regulated Mod until you Know and have the Ability to...

Measure the Ohms of an Atomizer.
Calculate what the Amp Draw will be on your Battery for any given Build using Ohms Law.
Understand what a Battery CDR is.
Use only Batteries purchased from Reputable Battery Sellers.
Use CDR's that have been Verified or Calculated independently by someone like Mooch.

18650 e-cigarette battery (3000mAh ) should do the trick.

No. That is the Problem.

You Can't just use Any 18650 sized battery in a 18650 e-Cigarette.

And the Choice of 18650 Battery is CRITICAL in a Mechanical Mod.

:danger: Too simple and vague of an answer.

We still need to know the overall resistance of the coil(s) to make an educated answer. If the original posters' resistance measures 0.2 ohm or lower, a 3000mah battery won't be safe because the continuous discharge rate will be 20 amps or less and he will be over the safe limit. In vaping, the amp rating (continuous discharge rate) is much more important than the mAh capacity.

Battery identification can be one of the most difficult aspects of battery purchasing. All batteries are not created equal and just because two batteries are labeled 18650, does not mean they have the same capabilities, characteristics and safety features.

How do you know what OHM to use then?

It's Simple for a Single Battery Mech Mod.

You Divide 4.2 Volts by the Constant Discharge Rate (CDR) of your Battery minus a small Safety Margin. This is when the Ohms of your Build will draw the CDR Amps with a Freshly Charged Battery.

Example.

You have a 20A CDR 18650 Battery. So you subtract a Small Amount as a Safety Margin. Say 2 Amps.

=> 4.2/18 = .23

So the Lowest Build you can use with a 20A CDR Battery is .23 Ohms.

You can Run Higher Ohms if you like. But you Can't Go Below .23 Ohms for a 20A Battery
