Great idea. What kind of box? ANd if you have a box, you can get a tank and a dripper and switch off.
I don't know anything about the box other than I think perhaps and I could be wrong 100watt? Or maybe that's for something else I'm truly trying to figure this and everything out.
You are using a 20A CDR battery. If your battery is labeled 35A it is not the CDR. It's the pulse. A 30A CDR battery is the highest that exists today. Many "rewrappers" label their battery with the pulse to lure uninformed into buying their batteries often at inflated prices.

Regarding CDR & Amps: Everyone is free to set their own parameters, and I can only say what mine are.

I try to never exceed 50% of the CDR (continuous discharge rating) of a fully charged battery (4.2v). So with a 20A battery, that would be 10A. This Ohm's Law Calculator tells me that a .4 ohm build is as low as I would want to use.

The reason that I place a 50% limit is because as a battery ages the mAh of the battery degrades, as the mAh degrades so does the batteries c rating (amp limit). So down the road, a 20A battery may only be a 10A battery.

Since you are new to mech mods and/or rebuildables I highly recommend you spend some time with @Baditude & @Mooch (two of our resident battery/safety experts) and visit their blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.

Mooch's blog on his bench tested batteries: 18650 Safety Grades -- Picking a Safe Battery to Vape With

Baditude's Blog - Table of Contents: The blogs that address battery safety, Ohm's Law, CDR (continuous discharge rating/Amps) and how they all work together are detailed below:

BATTERIES

Battery Basics for Mods: IMR or Protected ICR?
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.

Purple Efest Batteries not as Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.

OHM'S LAW

Ohm's Law for Dummies (Vapers)
* My attempt at explaining Ohm's Law in layman terms and how it relates to vaping.

Explain it to the Dumb Noob: Ohm's Law Calculations
* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.

BATTERIES - WHERE TO BUY

Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.

* RTD Vapor
* Illumination Supply
* Lighthound
* Orbtronics
* Battery Junction**

Note: **Ships to Canada
Thanks for the info in at work so I have plenty of time to read up now! My batteries are what I said in my first post but I left out the they are 35a.

Welcome Joe (Jock/Sandwich)! Congrats on getting away from the cigarettes. Took me 25 years to do.

Listen to the others - and read ALL of Susan's links. You *REALLY* want to be well-versed on Ohm's and Watt's Laws when you start using unregulated mods (and even with regulated mods - can't throw just any ol' coil on any ol' battery/device.) We just don't want you to be a statistic!

There's absolutely NOTHING wrong with using those kinds of devices, as long as you understand how and why they work. (So, don't get rid of it - just get a little more "edumacated" to use them safely.)
Thanks I will not get rid of it but I will look more into the safety factors in play for sure. It's a giant learning process right now and I'm still learning to crawl. :)

Why don't you figure out what kind of box before you spend the money, and then come ask what people who have one like and dislike about them before you do? Your money, you make the call. But it's a thought. And no offense, but your batteries "say" 35 amps, they aren't actually. Or more accurately, as @Susan~S says, that's the pulse rating, not the continuous rating.

I'm trying to use the same setup as my buddy I'm getting same box as him I used his for about a week and enjoyed it. My battery says max continuous discharge current : 35a
Pulse discharge current :80a
300ty cycle > 60% of first capacity

If that means more, I'm am trying to learn it's a little over whelming ATM so forgive my ignorance. :)

Ok, guy, you make the call on the box. No offense, I-- we-- are just trying to help. As to the battery, what I am telling you is it may well say that on the label, but it probably doesn't have that under the hood. There simply are no IMR batteries available on the market with those kind of specs, no matter what the label says. 30 amps is a good as it gets.

I got the rig and got some 3 and 6nic juices and I haven't looked back since I love the clouds the inhale/exhale the building and information of all of it like learning a new interesting hobby.

Welcome! Now that we have you on the vape side, beware of Shinyitis! Vaping can become more than a hobby when this kicks in :cool: You'll see ;)

I'm feeling like this is getting more aggressive than any of this is supposed to I'm not saying your wrong anything of that nature and I certainly am taking everything your saying into consideration for all my choice in the future concerning all my vaping needs that's why I'm here. I only posted what was on my battery for more clarity I had read about these purple efest batteries not being labeled appropriately.

The stuff I saying I'm getting is only based on what tiny fraction of information I know. I can't pick what I want until I know more about it that's why I'm here and looking to make a better educated buy.
All of that being said I will bow out until I find out the precise equipment I want I will read more over the site on my own to figure out the pieces I'll get.

My battery says max continuous discharge current : 35a
Pulse discharge current :80a

Manufacturer's listed Specifications:
  • Rated Capacity: 2800mAh
  • Nominal Voltage: 3.6V
  • Voltage at end of Discharge: 2.5V
  • Max Charging Current: 4A
  • Standard Charge: 2A
  • Max. continuous discharge current: 35A -- who knows what this really is or what it means.
  • Continuous discharge current: 20A
  • Pulse discharging current: 80A -- we can know what this means either. Not an industry standard

This is one thing about typing on message boards/forums. One never gets the true "voice inflections" and "underlying intent". There are a LOT of batteries out there that claim they can run a lot higher than they really can.

Mooch's blogs have a great reference for various batteries and their capabilities. Like Susan, I also treat my batteries at no more than half their advertised rating. If a battery claims to be a 20A battery, I treat it like a 10A battery and even then, build to something that pulls no more than 50-75% of that value. I'm just paranoid :)

Your battery is fine, as long as you don't try to overdrive it (i.e. too low of a build.) Quick Ohm's/Watt's Law (if you're interested)

Battery, when fresh off the charger is about 4.1-4.2 Volts. We'll use that as a starting point.

Ohm's Law: Voltage = Current * Resistance
Watt's Law: Watts = Volts^2 / Resistance (or Watts = Current^2 * Resistance)

So, if you're sporting a 1 ohm coil, Ohm's Law says that Current = Volts / Resistance = 4.2V / 1ohm = 4.2A

This is not terrible at all. Very well within the limits of almost any 18650 battery out there. (For giggles, the Watts are just a shade over 16 - 4.2^2 / 1)

Now, drop the resistance of the coil and we're starting to put the pedal to the metal....

Current = Volts / Resistance: 4.2 / 0.5 = 8.4 Amps. That's starting to get up in the world (Watts = 4.2^2 / 0.5 = a little over 35W.

Drop the resistance a little more, say to 0.25 ohms, and we're going to get the following:

Current = 4.2 / 0.25 = 16.8 Amps. NOW, we're starting to push a LOT of batteries pretty hard.
Watts = 4.2^2 / 0.25 = about 70 Watts. Not a lot of devices have the capability of driving that (without jumping into dual-battery configuration)

I think what all are saying is some batteries are not as advertised, so simply take care in their use. I have a number of efest batteries, but I don't build anything lower than 0.5 ohms on any of them (again, just because I'm paranoid.)

I'm reading Mooch's blogs diligently, as I'm in the market for new batteries, and I am going to "up my game" and get some better-rated batteries for my collection. I have a few that don't have a very high CDR, but they have a higher maH rating, so I use those with my Protanks and Kayfuns.

It's a process, Jock. I'm thrilled you're coming here to ask questions and to try to learn....

Good to have you, and good to hear you've quit.

All of the above is great advice. I'll tell you, I've been vaping for 5 years, 4 of them exclusively on mechanicals, and I'm wary of the hybrid top cap. Be extra super special careful.

And getcha one of these lil' things right here:

$5.86 Atomizer Resistance Tester (Ohm Meter) - eGo/510 connector / 2*AA / black at FastTech - Worldwide Free Shipping

$5.86 Ohm tester, shipping included.
Thanks I'll look into that.

Could you give me some insight on how to figure out what they are, also what would I remove that would be dangerous? The smpl mod is only a tube with a bottom button to engage the battery. If you or someone could help that would be awesome.
Hi Jock,

Well me too didn't have an ohm meter (and still don't have one, but have a couple regulated mods which tell me the ohmmage)

I relied solely on this website, which i advise for every vaper that deserves respect :)

Steam Engine | free vaping calculators

you can have a pretty good guess on what you are building there.

I recommend buying a cheap multimeter though, if you don't want to shed money on a dedicated 510 threaded device to check your coils.

Hey Jock, welcome! I was in your shoes as a new vape guy not too long ago myself! Congrats on making a good decision to quit ciggies!!

The replies you have gotten are ones of concern, not meant to be mean or judgemental!

Everyone here wants you to first and foremost, vape safely so in order do just that, it's all about doing your homework! Several folks here have gone above and beyond and to make all the info you need to vape safely with just a point and a click. Please take advantage of their generosity!!
