Discontinued The RBT Milaana (unregulated single 18650)

[Krazzykid]

I think in order for a battery to drain that fast somthing had to be getting hot as hell. There had to be somewhere for that much energy to go. I've just been thinking about it ever since I read about it. Sorry about the troubles @Vape Dr. One things for sure its not working up to par. Not from what I've witnessed.

I would generally agree here about the heat, if it were a properly working cell. If the battery had the amp capacity it should have, something would have had to heat up real quick for that kind of voltage loss (hot battery, hot contacts, wires burning themselves out, etc.) If any of these happened it probably would have been pretty obvious due to their proximity to the wooden body. If the battery took the brunt of heat in this scenario it would most likely have vented.


If the battery has an extremely diminished capacity (DOA cell, it happens), then it will basically just drop below usable voltage extremely fast. Since it won't have the amperage capacity there really won't be any extreme heat generated where it shouldn't. Obviously I think it's this scenario we are experiencing. My

Edit: I could be wrong though. I'm just working with the evidence made available and my experience/knowledge.

The only other factor i can think of would be screen depth. Obviously the closer the screen pushed to the tip the hotter the vapor will be

 

[HD Springer]

@Krazzykid spot on I think. And @IAmKrazy2 crazy how a little distance can make a HUGE difference.

 

[nosmoking]

Do you think @nosmoking ypul be able to see any international orders when they show up on your system, think it's great you'll able to predict the future by telling us where the Milaana will be seen next, in my hands eventually

Suppose it depends if he's using the same company to sort the international orders as the domestic?

Unfortunately, my vision is restriced to domestic shipping. I also have not seen any new shipping labels added since the 4 I saw added yesterday. I hope to see some tomorrow but we must remember he is batch building so that he can get a bunch out each shipment.

I am loving the reviews, keep them up guys!

Yeah, but not necessarily as its still possible to scorch a small load thats far away too, i dont think thats the issue here (though i generally agree)

I just had an amazing concentrate experience with Milaana.
I placed one strand of the provided stainless steel mesh shreds into the short stem bowl (shallow screen dome side). I proceeded to load a dab large enough that I was sure the mesh couldn't possibly hold it all. Spoiler, it did.

I began with a 5-10 second hit with no preheat, just to get the goods melted and absorbed into the mesh.
I followed that immediately with a 3 second preheat and a somewhat fast inhale speed. I was met with copious amounts of tasty vapor. I'm almost positive vapor was pouring from every hole on my head .
I began with a fresh battery. I will try to replicate with a battery depleted to 3.7V later on, for .

That's all the info you get from me right now. Time for video games.

Hello All!
I got a sony vtc-5 and an R25. that's all they had at my shitty vape shop and they were $17 a piece!
They are fully charged now I want to let them sit a bit longer, eat and I will try all 3 fully charged back to back with a short stem and my stem screen 3/8" from the edge.

Thank you @Shit Snacks and @AJS I hope it's a bad battery as well.

How much spring is in the positive terminal? Are you getting a good complete connection at both ends of the battery?

@MrPeanut The spring inside is perfect, makes a great connection. That was the first thing I checked.

Sorry about the troubles @Vape Dr. One things for sure its not working up to par. Not from what I've witnessed

Thank you @HD Springer I hope it's the battery, if not no big deal. I will just send er back and have er checked out. No worries.

This is funny you say this @IAmKrazy2. I have the screen in the mouthpiece in about as far as an UD and it almost seems that my long and short stem both make contact with the oven screen. I stuck an extreme Q elbow adapter in the Mi and it felt way more snug, like a lot. I don't think the heat escaping would cause my unit to run that cool, but yes, the oven screen actually seems up rather high but I have nothing to compare it to.

Yeah, but not necessarily as its still possible to scorch a small load thats far away too, i dont think thats the issue here (though i generally agree)

Yes @Shit Snacks I thought so as well, I moved the stem screen UD close and pretty much had to hold the button full throttle for 5 seconds and throughout a super slow 10-15 second draw and my battery would die before all the ABV turned brown.

I don't want to get ahead of myself or jump to conclusions. I am very happy with everything about the Milaana and plan on ordering a back up that I can stain and make look super sexy.

I may have a problem, I may not. If so, no big deal. Shit happens. I fully understand the heater technology RBT uses and I am a fan. I'm not goin anywhere.

Sorry about the long post I hate them, my bad. I'm going to go eat and hopefully I'll be back with excellent news!

Good luck! To me UD close is actually rather far though, I'd suggest giving close bowl basket style (or even close stock style) a try as well just because. EQ screens aren't supposed to be used, but you can put an RBT screen in the stem lile that, right close to the heater screen but with an inner glass rim vs the EQ's metal outer rim

To some extent, I think less may be more when using concentrates in the Milaana. I overpacked a few times in the name of science. Whoops.

 

[little maggie]

I went back to your original question and noticed while I was on mobile that I hadn't previously seen that you had identified your charger at the very end of the post as the eFest LUC v2......the eFest 2-bay charger with the digital screen. It is the other eFest LUC v2 BIO that can charge at 2A. I had considered the 4-bay eFest charger at one time because of its ability to charge at 2A which is where the confusion on my end came from......I hadn't realized that the 2-bay LUC v2 could only charge at 1A.

So that being the case, then your charger should only be capable of charging at 1A max .....which is not going to cause any real stressing on your batteries at all since the standard charge rating for both of the RBT batteries (Samsung & LG) is 1.25A and the max rating is 4A.

It is the LUC v4 (4 bay charger) that can charge 2 slots at the same time at 2A. You should see the current amperage that the charger is utilizing in its charge right on the display......if it says 0.5A then you want to change to read 1A.

However if you are in no hurry and are charging overnight rather than during the day then charging at 0.5A is entirely OK if you want to baby your batteries. The rest of my prior post still applies......let them charge fully and even sit at 4.2v until the charger indicates the charge is complete

No. I do have the LUC V4. I must have written it down wrong.
I'm off to visit my yet unnamed Milaana for the first time.

 

[Vape Dr.]

Thanks @Shit Snacks I took your advice before trying and I pushed the screen half way down the stem, about 1/2"

I then did what @KeroZen suggested before and filled it up with 1/3 the way and gently tamped it.

ITS ALIVE!!! I received a bad battery. That's it. Problem solved.

I absolutely love the simplicity of the Milaana.

I ran the SONY VTC-5 through 4 chambers I think a lot of vaping just occurred. I got 4 nice hits stirring after 2 hits and i could have taken another one on each chamber but I was trying to hurry up and test the battery longevity. It was night and day.

The 25R seemed IMO to actually run a bit hotter from a fresh charge as the sony stayed consistent the whole time. The 25R was great, still is. I'm on my 5th stem.

So my unit works as intended and I couldn't be happier. I actually had a feeling it was the battery not the unit because it discharged so fast. Gotta have faith.

That being said, I do believe my unit runs a bit cooler as was discussed at .5 ohms. It just happens that being a low temp guy I feel like I have a built in potentiometer just for me.

With the sony which I perfered because it felt more consistent throughout worked great.
I never came close to combusting and I hit the button and drew 5 sec let off 2 sec button 3 seconds.

I didn't get EVO clouds but very nice clouds (I'm not a cloud chaser so it doesn't bother me).
The 25R works very well, seems hotter faster at first then a bit more consistent. I didn't run either battery all the way down and was enjoying tasty instant convection hits before swapping.

AND! I just saw the Milaana stem @Alan made on th HI thread! Amazing! I need one!
Thanks guys!

A completely satisfied customer!

 

[killick]

@Vape Dr. Yay! Now, I don't have my Milly yet, but if it's anything like the Zion you should spend a couple of stems trying to overpower the heater. Beware tho, as this is where combustion can sneak up suddenly

 

[little maggie]

Another couple of battery questions. First how do you know what brand battery came from RBT? I don't see it written on it. Second I found some batteries I got somewhere and wonder if these will work. Not sure of the brand unless it's mainfire which is written on it: 2900mAH, ICR 18650- is this ok for the milaana?

 

[Vape Dr.]

@little maggie the RBT batteries are LG HE4 batteries. I don't know how well they work, but I can tell you SONY vtc-5 and LG 25R batteries work very well.

I just did research and you don't want to use IRC batteries because they can explode I read.

I believe the stock batteries are 2600 mAh, at least mine are.

I once heard from wise battery gurus: "never buy batteries that have "fire" in their name"...
I know, it's a bit general - but you will be rather good sticking to this

 

[anasrzi]

Does everyone get a free battery with there Milaana? I have a couple of 18650 already both I use in my Dabbie, ones an efest think it is 2600 one sound right? The other looks unbranded but swear it says lg and it's a off yellow colour.

 

[cannabis.pro]

You definitely want IMR (or INR even better), especially for a non-regulated device. ICR batts are less predictable and more volatile.

A good general explanation.


Edit: Another good source with more in-depth explanations.

@little maggie see the first link up there from @TheDudeNextDoor
I think due to the unregulated nature of the Milaana, you want to steer clear of the ICR type.

 

[KeroZen]

Yes as said above, anything with fire written on it is asking for trouble. Those are crap cells for weak flashlights in general. Not high drain cells suitable for vaping.

ones an efest think it is 2600 one sound right?

Efest are rewraps but it could work. Try taking a couple of hits with it, then remove the cells immediatly and check if its temperature rose. If it gets warm quickly, don't insist, it's probably not up to the task.

If it says LGDBHE41865 you're set.

 

[dac13]

So has anyone attempted staining their Milaana yet? I am interested to try it, maybe I will give it a go and see what happens

 

[MrPeanut]

In early adaptations of the Zion (2x4 units) an all natural soy based stain was used (TimberSoy sp.?). Not many people that tried it enjoyed it as even after curing it had an odor. I am assuming regular stains would be even worse? Try it? Maybe it can be sanded off if you don't like it. Also not sure what, if any mods would impact the warranty.

 

[ragnorokk]

I stained my Zion. Difference between oil stained (well, home made wood butter) Maple and stock finish:

 

[TeeJay1952]

@MrPeanut are you saying the qualities of Mercy are not Stained?
@ragnorokk I hate everyone with 2 zions.
