Need something small for work...

[bogeyjim]

I've done a lot of reading on this. I've been gone for a bit. Happily vaping away with my MVP and my eGo twist at work.

Well the eGo .... the bed yet again, this is my third one.

I think it's time to try something different as I'll need to buy 2 eGo twists again to be good a whole 8-10 hour day at work.

What mod do you recommend that is small? I was going to purchase the SVD tonight but that thing is a monster, and I can't really use something like that at work lol.

Any ideas? I looked at the Zmax mini, it looks nice but a tad too big.

Any small telescoping mech mods that are a reasonable price?

If you're not looking for something flashy, a K100 mod might be good for you telescopic, and small-ish in 18350 mode. If you're looking for small, 18350/18500 is the way to go, depending on the mod. Might wanna keep an extra battery on hand for an 18350 though.

Yeah, the K100 or K101, though a bit heavy with the battery. That is what I use at work along with my Ego-C.

 

[Paul.K]

For work I use a Provari mini with 18490 mode. It's tough enough for for harshest work environment and gets me through a 10 hour work day. I do carry a backup battery and some juice tho. Not sure if it's in your price range but probably one of the best regulated mods around with great build quality and warranty.

Reo mini.....................

 

[bogeyjim]

That K100 is looking really nice and the price seems right. 2 new eGo twists will put me at 50 bucks..... this and a couple batteries will be right in that price range as well.... how long does an 18350 last usually?

 

[bogeyjim]

OK, just purchased the K100 with a couple batteries and a charger!

Thanks everyone, excited to get this in!

I went with the mech mod for when I start messing with sub ohm stuff, this will be good to have

Next purchase is the SVD at some point, for home use only

Do your homework on RBA's; battery chemistries, specifications, and limitations. An 18350 battery won't be able to power sub-ohm due to it's 6 amp limit. You'll also find even a 1.0 ohm coil on an RBA will drain an 18350 battery in half the time it takes a normal juice attachment.

You really need to use the 18650 size "high drain" IMR or hybrid batteries to do sub ohms safely. And sub ohms less than 0.8 ohm need special IMR/hybrids that have over 10 amp continuous discharge rate. See the first link below.

Isn't that why he got telescoping?

I'm running an Ithaka @2.5ohm on top of a Nemi with Kick @ 8 watts in 18500 mode(18350+kick) - use at Breaks/Lunch only

Gets me Nicely through my 12hr. shift + commute.

Since OP is new to or hasn't gotten into RBA's yet, his focus appeared to me to be using primarily a smaller mod and using sub-ohm using a couple of 18350 batteries. He didn't mention which size of a "couple of batteries" he purchased.

I was only pointing out that the 18350 size battery won't do much good for a sub ohm RBA. That is why I included those links so he could research what would be required.

 

[bogeyjim]

Nope, I've definitely done my research and figured telescoping would be best for me.

I can use the 18350 when out and about or at work, etc...

When I get home, rock the 18650 when I start doing that sub ohm stuff I do appreciate the links. I still have more to read, but I do have a good grip on discharge rates etc..

Thanks!

A .8 ohm coil with a full battery assuming that all 4.2 volts will get to the coil (which they will not) is pulling 5.25 amps. That is no where near a 10 amp continuous limit.

How about a .6 ohm coil? 7 amps. Still quite a bit of headroom to the limit of a 10 amp battery.

I know that you are all about being safe and promoting safe use of batteries Bads, but I respectfully think your .8 ohm limit on a 10 amp battery is very conservative. My biggest issue is that once you step up over 10 amps on a safer chem battery, the mAh rating drops real quick. That's a pain in the .... to carry more batteries and be changing them more often.

Anyway, I'm curious why you have been using the .8 ohm at 10 amp cutoff lately. Is that a recommendation that you are passing on to others or is that your personal limit?

 

[23skidoo]

Bogeyjim, what are you using as an atomizer at work?

The reason I ask, is because higher resistance atomizers may be problematic with a mechanical mod. So you may need to change that up a bit to compensate for the lack of adjustment you twists had.

the smoktech e-pipe mech mod is a very small, simple and durable device that fits a 18350 protected 1200mAh.

I agree... Built like tanks and very well made. Can't wait until after the holidays to get mine!!

You are looking for something that doesn't exist. You can get small battery that won't last all day or a large battery that will. My suggestion is if you want small get two or three of them to make it through the day.

At home I use a rather large provari and when I go out I carry two three twist.

I use a 2.0 boge in carto tank usually.

For the k100 I ordered 2 1.8ohm Evod's to try out. Not sure which way I'll go but I want something semi compact. I think the evod with the k100 would be a perfect size. I'll just have to see how it vapes. I ordered 2 18350 batteries. That should get me through a workday. I have the MVP for home use.

The 0.8 ohm cutoff for the easily available IMR/hybrid 10 amp limit batteries is one that I and PBusardo recommend. Research this info on his battery recommendations from his Taste Your Juice website. If you happen to have a better authority on safe battery use, then let me know.

" tasteyourjuice.com/wordpress/battery-information "

This leaves a acceptable amount of safe headroom. It is considered wise to not push a battery over 80% of its specifications. It is also widely accepted that a larger battery is a safer battery, hence my recommendation to use a larger battery than an 18350 battery for sub ohm applications.

An 18350 battery has a 6 amp CDR. A 0.7 ohm coil will pull 6 amps, its limit. Pushing this small battery at that rate will drain it quickly requiring the use of several batteries. Also consider as any battery ages it looses its previous specifications. You may not notice any trouble at the start, but as the battery ages with use the problem will become more severe. Push the batteries a bit further and now you've entered the realm of thermal runaway.

Pain in the .... inconvenience (lower mAh but higher amps) vs the higher potential of thermal runaway (higher mAh but lower amps)? Which is your choice?

Thanks for the reply.

I fully understand the issue with 18350 batteries and was speaking about 10 amp 18650 batteries, which I see I didn't make clear in my previous post. I should have made that more clear.

You say you and Pbusardo don't recommend pushing a battery over 80% it's capacity, and with that I agree, regardless of it's size. Know your discharge ratings and stay within that 80% range. Makes sense to me. However, the recommendation to stay at .8ohms or higher on a 10 amp battery is closer to a 50% range when talking about maintaining a safe headroom. That's what I was not understanding.

I understand erring on the cautious side when making recommendations, but if I can run a .6 ohm coil that is drawing 7 amps max on a 10 amp battery that is considered safer chemistry, I'm still within the 80% recommendation and actually only at 70%. My panasonic 10amp batteries give me roughly another 600mAh over the higher discharge rated AW 1600mHa and are still within the safe range.

Could I end up like your picture? Maybe. Have I carelessly put myself in an unsafe situation with my setup? I believe not.

Am I missing something with my math?

Those 2.0 cartos should work fine with the K100. Sounds like you are set with what you have now to see how you like the mod. Those Evods are nice clearos, and a lot of people love them. The heads on those are easily rebuilt as well, and are a great step into seeing if you like rebuilding or not.

I have a K100 and with the 18350 it is tiny. Almost too small for me. Please be careful when you tighten the telescoping part of the mod to fit your battery. The way the K100 is designed, if you tighten it too much it can continuously fire. I think with 18350's the tubes bottom out before that happens, but with the bigger batteries it can definitely happen. Check your switch throw before you screw on an atty to make sure it's not bottomed out and have a decent amount of throw and you should be good to go.
